chi The process of a complete mobile phone

plastic decorative surface effects can be done, casting, metal sense of the advantage of strong, high quality, good wear resistance, plastic decorations direct hot glue or buckle in the shell, the thickness 0.9 ~ 1.0mm, IML piece is a silk screen pattern FILM has been placed in plastic molds for injection molding, this FILM can be divided into three layers: the substrate (usually PET) , INK (inks), wear-resistant materials, injection molding is completed, FILM and plastic integrated, wear-resistant material in the external wafer of plastic material which mostly PC, PMMA, there is the role of wear and resistance to scratching, the surface hardness up to 3H. IML hot glue or deduction items directly in the shell, the thickness of at least 1.2mm.
Nickel-metal decorative pieces in the film is the maximum commonly used, beautiful appearance, svelte tweezers thickness 0.1 ~ 0.15mm, mold can not do better lace diameter as small as 0.3mm. If steps are necessary to mold the system to do curving, the overall thickness of no more than 3mm, the side pull level mode is greater than 10 degrees.
aluminum trim thickness 0.4 ~ 0.5mm, because the soft, brushed surface made of ruled, chaotic pattern, ripple, swirl marks and so on. Anodizing is also called corrosion treatment, is the current role of the metal surface formed by a layer of oxide film, wealthy colors, beautiful color, good electrical insulation and hard wear, corrosion resistance is very high. Sand blasting is to be decorative or fine film optical reflector surface to meet the soft gloss, and other special design needs. After the processing of optical processing are high in aluminum ramp brim milling out a sunny side, the same shape as lead C angle. thickness of stainless steel decorative pieces
0.2 ~ 0.3mm, high hardness than aluminum neat, the previous single color, but with the technology now color has been gradually enriched. Other pieces of stainless steel decorative effect of the main drawing surface dispose, high light (mechanical polishing), Ma surface (dirt), matt, etc..
17.
the structural design of the battery box cell phone battery stamina warehouse place, requiring the battery easy to load, good contact, do not rotate dropped out, easy to take, the structure of the battery carton must meet these requirements,
a. battery box as the basic material thickness 1.0mm, the bottom of the battery case as closed, there are components to dodge component, no component plastic shell covered with as many as possible, to dodge exposing large areas of the PCB.
b. gap, pick and place the direction of unilateral gap 0.2mm, Taper 3 to 5 degrees, the direction of the unilateral loosen of non-access gap 0.1mm, Taper 1 to 2 degrees. battery and battery box at the bottom of the gap is 0.1mm. Battery Cut the bottom of plastic containers and plastic shell gap chip components remain 0.2mm, the bottom of the battery box rubber and plastic shell excavate the gap left SIM card connector 0.5mm.
; c. the instruction of 2 pick and location the battery needs to be done with the buckle and the battery, to prevent detaching of knitting the quantity of the battery can take location according to the simulation to assess the period of circulation. pull the hand position to set alongside slightly wider than the nails pits, simple finger mowing out the battery
d. battery box to protect the battery connector, battery into the battery box that can only touch above shrapnel to the battery connector, and not allowed way to the battery connector body, so as not to drop test the impact of causing mar to the battery connector.
18. motor
motor design is a weak mechanical vibration on the mobile phone electronic components, when the user mute, through the motor's vibration sensor allows the user to call the motor is divided into cylindrical and flat shapes, connections are wire-type, shrapnel-type, there are SMT type and plug-in.
wire type, shrapnel-and plug-like cylindrical body outside of the motor is usually set in a rubber sleeve, we just played around in the shell of bone wrap rubber sleeve on it, bone and rubber sleeve around the gap between the zero Bone conduction angle around the top keep to facilitate the motor mount. careful to quit enough for the eccentric rotation space, an vacant shell to avoid eccentric rotation range of at least 0.5mm.
smooth rubber sleeve with no motor, side pressure on the board, the other side of the direct use of double-sided adhesive on the housing, from around 2 / 3 of the bone can circle around, you might ask Why bone to reside around 1 / 3 of the gap? the original structural design not only to consider the assembly and authentic, also easy to remove should also be considered. With 1 / 3 of the gap, the removal of a pry the tweezers when the motor can, incidentally one, flip phone magnet positioning sensor on the bone to linger around 1 / 3 of the gap, but also the same cause. flat motors can also be fixed on the antenna bracket on the side of the bracket with double-sided adhesive on the antenna, antenna stand around from 2 / 3 laps around bone, the other side of the bone with a shell length of rubber hold him down, pay attention to inhibit bone glue can not be head-on motor, rubber bone and a 0.3 motor climate gap between, affixed to a layer of foam about buffer to protect the motor.
19.
the structural design of the stylus pen only in the mobile phone with touch screen only used in general fixed in the next shell, use pull out the stylus into the cap, the pen tube and pen, hanging pen cap on the need to do, to do with a pen hanging points to pull the hand of the turntable to facilitate the pumping out pen, pen tube is hollow stainless steel or copper, can be made as needed with one or more segment of the elongated section. nib with a round groove, the groove by inserting after the positioning under the shell,
; 20.
the structural design of the battery cover the battery, SIM card and T-FLASH card should be designed to be replaced, hid them in the next shell of the battery box, and then design an easy to open and close the battery cover protected them, the battery cover material can be plastic parts, the surface can be affixed to decorative parts such as lenses or metal films and so on can also use stainless steel sheet bending shape, the structure including the battery cover pull the hand position, buckle, side buttons, call points, pull the battery cover hand positions when the force is to take place, buckle, side buckle is the battery cover, insert the retinue shell structure when the bite, shriek point is inserted under the battery cover to prevent the exit after the lock shell structure.
21. wear Design
rope hole is a hole through the phone rope to the structure of fixed ropes, lightweight phone that can wear a chest belt hanging before, but now with the surface of metal decorative pieces of mobile phones additional, and long standby battery resulting increase in volume, have made the gradual increase in the weight of the phone itself, there are also no longer require customers to do a lanyard hole. Anyway, I do not recommend all the phone hung on the chest, in addition to the security context does not allow here, the mobile phone battery insecurity gradually speed up people are cared about, or hides it in his pocket!
chasm through the structure of rope generally do in the next shell, use the breach at the antenna bracket see every pin, row position is indispensable, but also pitfall the lanyard to ensure adequate strength of bone bits.
one program to determine
motherboard design company in the phone, ordinarily divided into the sale ministry (hereinafter referred to MKT), Department of shape design (hereinafter referred to as ID) , Structural Design Department (hereinafter referred to as MD). A mobile phone project is a piece of embark from the appointed beginning, the needs of our customers choose the right according to the mall the motherboard, where to get a motherboard from a solutions company, 3D map, find a style of design company Design the shape and structure. Customers also find the design company to design directly fashionable motherboard design, which requires phone companies to structural engineers and program to do according to customer requirements stack new motherboard, and then do follow-up, not to introduce here. When designing the company signed one concert MKT and customers, to get customers to the motherboard, 3D map, the project was officially launched, MD's work began.

Fourth, structural modeling
1. data collection
MD start modeling need ID to provide frames of is beneath the process ID delineate the outlines of the map, and be skillful to liken a true reflection of ID's design intent, the output file can be DXF and IGS format, DXF format whether it is, MD take a another perspective in the frame at six in the CAD view of the rank gracefully, so that the scanning lines PROE transferred (instantly in the PROE rotating frame, yet a differ view of the difficulty.) ID is likewise responsible in the rhino different outlooks to help MD to wireframe view of the position by six planned the format saved as IGS, MD just described in the ROE in line on it. One might query, everything actually is to scan lines, ID frame provided surface is not directly used to draw easier access? No, ID is not accessible parameters of the frame can not be modified and amended, limited follow-up structural adjustment, so I do not suggest MD to provide the frame instantly by ID . merely also directly to the ID does not scan lines JPG picture, so to depict his line of MD, it is extra chaotic, picture zoom ratio among the width and breadth may change, MD detailing of the line may have a larger ID of the design ambitious different, and so is not recommended ID does not scan lines directly to JPG images.
rhinoceros if there is to do with the phone ID reference surface the better, in fact, ID also can be modeled, and the degrees of freedom than the PROE large rhinoceros, so ID MD faster than the speed of modeling, only ID on the pull mode and dismantled touch absence of perception may be out of the surface and the actual construction is slightly different, the structural design of the follow-up of little help, only used for reference.
Also, if there is a copy version of the prototype to provide a reference, or can be base online ready-made images, which can provide expedience for the MD modeling. motherboard yet has the 3D is the MD, to be used directly to find out, but, with the best and the ID before the check again to see if there is no get wrong, there did not receive the updated version, or other structure, may not finish the plate only to find afflict.
2. the idea of ​​dismantling
MD hands well before the first phone to how the demolition of parts, make phone has an essential idea,timberland bonus 日相菅直人与美驻日大使协商美军机, that is, the phone must have one of the main shell, the main strength is the best thickness is thick, the whole strength of thanks to him, to pay the other parts are attached to him, so that the structure was mighty and mobile, is relying on the fixed board in the main, if appropriate for the thick shell body, usually the motherboard installed in the shell, thick shell suitable if the next body, usually the motherboard installed in the next shell,
dismantled seek simple, too massive too spread intensity will reduce mobile phone, the assembly will mushroom the trouble of Great, if not, argue the equilibrium and structure of some colleagues, and aspire to find the best program of dismantling. dismantled the program after setting, we must consider the Draft between each shell, and up and down forward the mold shell to 3 degrees upon, metal decorative pieces around the mold to pull more than 5 degrees.
3. the appearance of surface rendering
appearance side is the outline of the phone side, a good bend of a good surface, when the scan line have to be close to the ID of the frame, and adore the inspired ID is a structural engineer basic exercising. At the same time also to attempt to smooth lines, curvature as even as possible, to be taken into account Taper angle, if the ID of the line of Draft angle and structural requirements are incongruous, you can and ID consultation, and if mini impact on the appearance can be described by the structure contour line directly to the Draft amendments angle, if the plastic shell to retain Taper Angle on the ID of the creative havoc of large, may wish to think the four sides of the plastic mold line position to do, once and for all, is a high-end user phone, this investment is worth.
phone digit namely symmetrical fashion, exterior merely absence to do half of the face, the additional half to the back of the mirror to do repeatedly when dismantling the quondam, the achieved appearance of the surface before their retard and chart to flat the location, and then build the convergence diagram, the Omo and the motherboard together, look at the basic size namely adequate, and eventually you come and see encounter ID does not meet the chart requirements, ID validation the complete dismantling of the tin.
4. prefatory dismantled
This time the split pieces is made to the customer look and confirmed by the appearance of palm, and can not do hollowing, but the appearance of the parts can be seen to be drawn into a unattached, easy look to do different surfaces Push, the appearance of the surface of a rounded turn on the place to lead, the hand, can not be neglected. common assembly drawings of parts are named and distribution requirements, such as button is for button factory to do, can converge on one makeup, the purchase and investment in the fashion of a component prototype can be sent out, it is convenient.
5 . modeling data output
MD modeling is completed, the machine PROE six drawings in the making of view, dump the document back to DXF wireframe correction process ID label, complete construction of six-view mode with the incipient skeleton may be catered to the MD of the border ID are modified, ID needs to do the suitable update, and beyond complete the process diagram indicating the manifold components of the material and visual appearance of the surface process, shade printing alternatively laser engraving is even a membrane information, updated message on the process Tufei Lin, together with MD modeling 3D map can be issued to make the appearance of a palm.

Second, the design guidelines to get the motherboard production
3D map, ID and can not be called directly, but also the 3D map MD to turn into a motherboard six-view, and count the basic size of machine, which is MD of
basic skills, I put it as the company hiring interview questions, there is no neutral test done a cell phone will understand, even now the wrong respond To be more seasoned resume is useless, in truth, the answer is quite simple, to send touch screen mobile phone, for example, such as the length of the motherboard 99, the whole of the length measurement is joined 2.5 to each end of the motherboard, the machine length can be achieved 99 +2.5 +2.5 = 104, for instance, the width of 37.6 board, the whole width of the size that each side of the motherboard with 2.5, the whole width can be 37.6 +2.5 +2.5 = 42.6, such as board thickness of 13.3, the whole the thickness of the size is above the motherboard with 1.2 (including 0.9 and 0.3 on the thickness of the foam shell thickness), coupled with the motherboard below 1.1 (including 1.0 and 0.1 the thickness of the battery cover on the battery assembly gap), whole thickness can be 13.3 +1.2 +1.1 = 15.6, the answer is not the only, at all times that means of calculation on the line
ID design appearance also highlighted the need to pay attention when the issue, this is a complete design guidelines .


VII. offer map data compilation
do here , mobile phone design a temporary close, do first important entity --- to offer plans to provide plastic mold, plastic mold making needs 18 days all but, this is the top priority of the entire mobile phone project, Prior to this, the customer chose model plants need a few days, first the structure initially completed to the customer to contact the supplier, the process can shrink the time of the project, the use of customer contact the vendor a few days, we can optimization of the product, evaluation and revision, and other customers selecting the suppliers, we also completed the structural design, just into the mold and mold supplier evaluation stage.
; should be noted that the plastic mold plastic parts offer plans include 3D map, BOM and ID tagging process. In order to data security, do not offer a do not give plastic parts, plastic parts need to purchase one less and converted into STP format is best, only offer convenience, inconvenient,mbt walking shoe, for other intentions. BOM chart only to the plastic part in order to avoid mistake rates. The above information only to the customer, the customer to contact the supplier, usually design company Business customers are not involved in this one.

eight, structural design optimization
Well, now we can settle down on their own to optimize the structural design, and design to chance a product, there are many issues that we need to muse and prevention, the need for hardware such as ground surface; board and Shell How to match between the body; how to increase the strength of the shell; shell how to improve the system to do and so easy to die.




IX, the structure of each structural engineer review
design made out of , the total can not have their own problems that need to check other engineers, then, in which the different positions,jordan shoes shoes, different angles of observation, there will be got to resolve distinctions in wrong on the change, took out a discussion question can make the class of drawings to a higher class. the reiterate are the other design engineers first by drawing the 1st trial, the trial took approximately half a day to day, the need for drawings in mandate of appearance, procedure appraisal, components of the upper shell and lower shell components, surface technology, the possibility of the mold, to generate 1 by one the order of assembly of a comprehensive inspection, and trouble smudges recorded. and then the second stage --- a collective review, the Department of the collective appraisal of the building is full and relevant ID designer to partake in the conference, the issue will be listed first instance, we express their views, mutual understanding, both to assure the drawings issued to the maximum level on benefit of the corporation, but also as structural design engineers a chance to study and correction, in Shenzhen, the more is a large design firm, the more care to the role of the collective appraisal.




Fifth, the appearance of palm production and appearance of the Hand of the system to accommodate the appearance
do have a special hand-mill, and production a candy bar handset 3 to 4 days, the appearance of the panel is solid. can not be removed, mainly used to confirm the appearance to the purchaser, and now look at the bottom Push the button pad can be litter-chip, with the feel, the same as the real machine. customers receive after the assessment, given modifications, MD is responsible for improvement, you can start the internal structure.

; six
structure refinement design the overall layout ought start start, I recommend that the structure of the first to do the overall maneuvering, which is to do up and down shell only lines, columns and chief buckle screw structure, finish this trilogy, the phone to establish up the framework. then emulate from top to bottom, and place the order from top to complete details of the structure and so, by on to the next is done on the first shell components, shell components do next, from the top and to the housing assembly is in the order they do according to the handset from the bottom of the top of the MIC, which is the whole fancy , characteristic to the local order can also do some adjustments to list for the location of such relatively large screen, I can do first screen, the other in order to do down. Please memorandum that each elaborate of the structure of a complete do it as many as the next detail, not to the back of the check and optimize the increased workload.
1.
Mouth of the production line ; internal structure began with the pumping of the upper and lower crust shell, generally take the basic wall thickness 1.5 ~ 1.8mm. zero clearance between the upper and lower case, as I said before how to determine the subject, suitable as the main petticoat thick only the jaws, the other is made public only a mouth, only I should not be too deep, and generally 0.6mm enough, for the convenience of assembly, may be appropriate to make public only the mouth or lead Taper Angle C angle.
; 2. screw screw columns
column is to determine the structure of the strength of the key machine,coloured ghd, usually on the motherboard will Column reserved for the six screws holes, do not consume as much as possible make use of them. screw column is also an important role in the fixed motherboard, motherboard installed in which case, a corresponding screw column some changes in train, not only screw column and the board to match pipe holes on the live board, screw the side column caught the motherboard to be done to reinforce tendons, so that the structure was solid.
3. the main button layout
4. decorative metal piece on the shell structure of
fixed decorative metal piece on the shell usually made of stainless steel sheet or aluminum, the thickness of 0.4mm or 0.5mm, with a thermal plastic, double-sided tape or buckle-bit fixed, the surface can be brushed, electroplating and laser engraving. which can be surface rusted aluminum into a kind of different colors, you can cut out the edge of the bright side.
5.
fixed structure screen screen as if the phone's face, to take good attention of them, build the wall? right, is to use a surround around a long bone on the shell up, hang on until the board has (left 0.1mm gap ), the LCD closed, even now the subject is the impact of external pressure on the shell around the bone, because bone around screen higher than the Well. screen positive can not be in direct contact with the shell, head-on screen will be crushed, must screen 0.5mm thick glue around the front of the foam, the foam is compressed thickness of 0.3mm, so the screen on the front and put the gap between the upper shell of 0.3mm. in front of the measurement of the thickness of said machine, where you We look at the front part of the thickness of the screen how the calculation.
order to facilitate the loading screen, we will add lead around the top of the bone angle, of course, if there are factors around the screen or to avoid the prejudiced abatement glue, put the gap at least 0.2mm, if it is chained with the motherboard screen avoidance FPC, FPC bone and the gap is around 1.0 or more to do.
6. handset
fixed structure is a mobile phone handset sound appliance, usually the top of the screen Department, in addition to positioning, it also needs to have good sound chamber sealed, the structure surrounded by a circle on the shell of bone surrounded the handset from the outside, and the bone around screen similar to bone but do not prop the handset to the main board around, wrap handset thickness of 2 / 3 would be ample. and then renewed on the shell of bone surrounded by a circle around the sound hole handset, built around a positive bone compression of the foam earpiece, surrounded by a relatively closed sound chamber, and finally in the final shell out the sound hole on the line,法国核专家抵达日本 德愿向日提供机器人助救援, a sound hole on the shell should be in the range of the handset within the sound hole.
From the appearance, location of the handset the sound hole will do some simple decoration, such as the cover sheet of a nickel mesh, can also be a decorative piece of plastic plated with dust network use, attention to decorative pieces of plastic commonly used iron plastic column means fixed, dust screen is attached to the earpiece sound chamber inside,
7. before the camera fixed structure
; before the board at the front of the camera, the use of PFC, connector and motherboard. by positioning the camera from the upper shell of bone around coat around cameras to positioning. the eyes of the camera like a mobile phone in order to ensure good shooting, the camera lens front part of the structure need to have a good stamp to prevent dust or alien stuff into the blocked line of sight, and we help of the lens and case foam separates the internal part of the outside is stamped with a transparent lens, in order to ensure good representation and wear light, camera lens glass material, the bottom of the screen printing, screen typography is planned to cover the lens with the shell double-sided adhesive tape between the body,
is worth saying that the camera lens assembly is in the final stages of assembly machine do the , co-shell locking machine screws after completion, use a clean wind blowing gun shots carefully, before the lens connected to the housing through the double-sided adhesive, and cover the lens.
8. power-saving mode
fixed structure of the lens with the lens than the less power-saving mode, power saving mode on some phones set, need to open a skylight on the compartment phone shell, so there's photographic ID to sense the brightness of the outside earth, which requires opening the case and stamped on the lenses, the lens page can be cut with a PC additional to the chassis directly to the outside can also be made of a light beam navigated injection molded plastic hot inside the enclosure fixed.
9.MIC
fixed structure ; MIC in the bottom of the phone, wanted, like the ear phones is to transform the sound into electrical signals external components, so let the voice of the outside world pass without hindrance MIC while also preventing the voice of the cavity inside the case affects the MIC, the structure is indispensable from the circumference of the bone, while MIC itself to be wrapped packets, only reveal a small hole in front of the sound sensor, front must also be a good eligible with the shell, the shell usually opens on the guide hole on the hole 1.0mm.
MIC linkage with the motherboard can be a wire, welding welding FPC or wear on the motherboard.
; 10.
the structural design of the main key mobile phone keypad according to the thickness of the main points can be divided into thin buttons and accustomed buttons, flip done before machines, when the slide machine because the thickness of constraints of space with the thickness of 2mm key is not to directly use silicone sheet plus the structure of thin sheet steel or PC can be a film, in order to ensure between the keys are not interlocked, sheet between the different function keys will be separated with a through-hole (such as the V3 mobile phone is the basic key to do so), the role of silica in order to get the keys feel good.
straight pedal on the market today to the bulk, I P + R keys as an example to speak about the structural design of the main keys to the structural design of the candy bar machine volume is divided into 100, I think that the structural design of key components accounted for 30%, 30% on the shell components, shell components under 40%, showing the importance of keys. P + R keys, including Caps Group parts, brackets and silica gel of three parts, and some key components and support in Cap adds a piece of shading between the paper to prevent light displacement between the keys.
; scaffold material thickness is determined under the keys, you can use PC or ABS plastic injection molding, thickness 0.8-2.0mm; can also use the PC directly punching sheet thickness of 0.5,0.6 or 0.7mm; key thick ample, the bracket materials 0.15mm thick stainless steel sheet, but considering the ESD (static test) when the impact of steel on board, we need to bend the sides of a steel cantilever, and DOME-chip network on-the ground, and buttons or PCB bronze foil on the ground conduction, silicon film thickness of 0.3mm, positive long-boss and the Caps with the glue water. on the back extend film DOME with columns and litter.
; 11.
the structural design of the side buttons buttons in the phone left and right side of the side or top side, function is usually the volume keys, camera opener, power opener, or lock key, etc. structure is relatively simple basic keys, side button on the motherboard to do with the position usually means wearing a fixed number of lateral welding mechanical key is pressed, a mechanical key corresponds to a function. mechanical side of the key advantages of simple structure , feel good. also must do FPC buttons, pad locations on the motherboard set aside by way of soldering face key board fixed a FPC, FPC, after bending toward the side of the key board, key board piece can sense the touch litter pressure. FPC board side-key convenience is that under the same side of the center keys can require some adjustment.
side button is usually part of the structural design P + R in the form used, and the main buttons do not compare side button key frame, silicone part of the indispensable help to improve the feel Buzhi Yu stiff, Cap with a skirt to prevent more drop out, keycap surface treatment can be a primary color , oil injection, or plating, the absence of LED lights, side buttons do not require light, and seldom do Crystal Cap, usually with concave features characters sculptured on the way to do in Cap.
; side button is a fixed enhancement in the side of the button in one ear and out the side, and then use the shell enhancement bone caught, mainly in the overall assembly process to prevent loose buttons, once after co-shell , the gripping part of the side buttons can not supply anybody achieve on the basic, the clamping portion with the gap is naught.
12.USB
the structural design of rubber plug USB rubber plug is used to protect the USB connector cover, to assist the opening and closing, usually the soft TPE or TPU material, USB stopper is structured into the body , pull the hand position, tongue, positioning col four parts, the color is dark or close to the color of the shell used, USB concave function of temperaments engraved on the body, pull the hand positions can be made out of style or cut a concave type. the tongue part is inserted into USB connector USB lid to prevent the loose rubber bone, positioning pins USB stopper is fixed to the shell upside down on, can be made outdoor the plug-type or direct pressure (direct card in the shell between the body).
similar structures on the cell phone also T-FLASH card or SD card in the stopper, the stopper can be longer make P + R structure, that body, pull the hand-some with hard plastic material, while the inside of the spousing, fixed part with soft material, hard plastic material and soft material bonded together with glue between.
; 13. screw hole rubber stopper of the structural design of the exposed surface of the phone
screw crown will influence the appearance, must be screw holes covered with rubber plugs. the battery cover screw crown, can do within the shelter. screw hole rubber stopper of the relatively simple structure, mold can be a USB stopper in the same mold, the mold factory by the making, plastic screw holes similar cylindrical plug for convenient and easy to take, you can hollow interior of the screw hole rubber plug and the shell outer surface contour surface to be consistent, as a small diameter (1.0mm diameter than the screw hat can be), if so two screw holes rubber stopper not the same as the external surface, are not interchangeable, you must screw hole rubber stopper of the foolproof groove on the cylindrical surface to discriminate between make. screw hole rubber stopper structure according to the different needs can and screw axis made eccentric, as long as they cover the screw cap on the line.
screws must be used because the machine apart, so in order to verify the phone has not been removed without approval opened, some contractors in the battery cover on top of the screw hole to dig out a platform affixed to a fragmenting, if you absence to loosen the screw hole of the screw, you must devastate the brittle paper. posted easy shredding of platform must be based on brittle paper size to design, platform shape slightly larger than the fragile paper, position, lower down than the level of the shell to prevent the fingers accidentally touch the fragile paper.
14.
fixed structure of the speaker phone volume is a strong selling point, which is made more sound chamber speaker high demand. In addition to the program requires a company to horn its best pitch to the outside speakers need to pay attention to the sound crater points:
; a. speaker must be closed before the sound chamber. speakers directly with the shell, the speaker must be affixed between the ring and the case closed foam, speakers must use the side of a long circulate around the shell of bone among, gap left side 0.1mm. If the horn antenna between the bracket and the shell separated, then the speaker and the antenna bracket foam ring must be affixed between the closed and the antenna bracket and the case must be affixed between the bubble ring Cotton closed, in short, the sound of the speakers on a sound hole through the shell scatter out.
b. the first sound chamber speaker shall be greater than 1.5mm. horn speaker sound chamber altitude is positive to the housing wall of the perpendicular distance, in order to ensure a high enough speaker sound chamber, or even the sound chamber inside the shell thin plastic to dig 0.6mm thick .
c. necessary to achieve the speaker out of the sound hole area of ​​15% of the sound area, the sound hole area is out of the total area of ​​the sound hole and. speaker is the speaker that sounds positive area after the removal of foam the size of the navel part of the speaker's sound chamber height of the higher requirements of the sound hole area of ​​the speaker the greater the proportion of the sound area, when the speaker's sound chamber height 20 above, the sound hole area can be a sound and speakers and other large area that is 100%. on most cell phones, speakers and sound chamber in the 1.5 ~ 4mm, the sound hole area of ​​the speaker sound out of an area of ​​15% to 20% , sound effects better.
d. the sound hole of the structure of the most simple way is directly in the shell hole can be round hole series, it can be a actuator strip the holes. To prevent dust and foreign matter into the sound chamber, can be affixed to the inside of the shell dust network, to beautiful, the sound hole on the outside can be affixed to nickel plate, PC pieces and other decorative pieces, nickel mesh sheet can be small in diameter to 0.3mm, the situation in the use of nickel plate, the shell can not affixed to the inside of dust network.
; e. tune afterward spokesman chiefly affects the cheap frequency portion of the ring, a smaller shock on the lofty frequency part, you can not do request. In order to get agreeable bass, components on the motherboard does not interfere with the case and the motherboard can be used with the antenna advocate, via the bubble affixed to the speaker later the formation of closed up behind the tune sound compartment. Now in order to get more awesome bass effects, speaker kin, there have been shaking speakers, according to the size of the sound speakers can produce different vibration strength of the vibration of the shell passed directly via the user's hands.
; 15. under the shell structure of
nailed camera camera under the shell on the shell structure and the nailed camera fixed structure alike to the use of PFC or connectors are interlocked to the motherboard, situate the bone need Wai, sealing foam and lens are necessitated, but the difference is the positioning of the camera under the shell by means of antenna brackets, antenna support under the shell surrounded by camera firm the sides and bottom of the camera. To ensure the Centre under the shell and the next camera shot shell hole centre discrepancy does not happen, the next shell or to the bone nigh positioning. The next shell is ended loading the camera lens neat and mirror after blowing machine dust, and finally fraught.
16. under the structural design of shell decorations
; next to the plastic shell decorations, IML parts, metal pieces, etc..
three mobile phone to obtain the shape of design guidelines to determine
ID, the first will limn the idea, the next focus culling program to determine the next two-three sketch, it is necessary to meet customer requirements of creativity, but also between the two three sketches vary in style, and then purified on the machine, drawing a complete machine renderings, as distant as possible for the ID during the MD to provide technical the support, such as art can fulfill,ghd dark straighteners, the structure can do a little thin, ID to complete the whole effect of adjustment by the customer and screening plans to finalize the program can begin to make structural modeling was transferred to MD.
X. Push the structure in front of the structure of the validation done then
Well, just on periodical, needs the help of physical design verification, structural Push to verify the structure played a role, so the structure of information, including ID Technology Push mark, BOM and 3D picture (of course, be referred to as STP format) , the structure needs Shouban making about 4 days, the appearance and size are loyal with the requirements and drawings,wholesale jordans shoes 一段电话录音，讲述一段某公, which is close to the last model, coupled with the motherboard and get the structure of palm battery, which is a real phone, do not be also merry early, carefully check the part size, look at the overall assembly has no problem, there is no improvement can make production more effective and convenient, and now more thoughtful in the future to a smooth point of the mold.
XI review
structure Shouban mold making is not required 4 days you, this time we can mark the ID process, BOM and 3D drawings to the customer, the program companies and the assessment of selected model plants, the review usually takes 1 `2 days, customers have their own technology if you can re- to check the program the company can accept the antenna signal to assess potential problems, mold making plant will be possible to mold the views put along a number of improvements, and improved feedback to the design. If necessary, the customer in conjunction with design firm and model plant with the meeting to discuss the views improve plant model, a model problems that need attention can be put amenable, design and mold factory controversial issues a final decision by the client to discuss the results in triplicate to pay clients, design firms and Save left end of each module plant, design drawings based on updated results of the discussions, plans to issue a formal mold, mold technology plans, including the final ID mark, BOM and 3D drawings.


second, investment projects during the follow-up
mold plastic parts mold takes 18 days just about, is not the time to do nothing? Of way not, the mobile phone in addition to plastic parts supplier, there are buttons, metal, mirror, nickel film, batteries, pen, accessories, etc. As long as this phone used, the same can not be less. because these parts of the evolution cycle shorter than the plastic pieces, plastic chips we can use this time of mold beginning quote, proofing and mold. as keys, hardware die around 14 days time also, some companies have put the plastic pieces, buttons, metal project timetable collateral reach. materials cheaper, you can work to the acquisition compact to the mold plant, mold factory before shipping the materials (such as foam, double-sided tape) accompanied to pay the specified position on the shell, thus greatly simplifying the process after the whole assembly.


thirteen, test mode and change the mode
or plastic parts as an sample, test mode and change mode is that suppliers after completion of the mold making plastic parts and molds try trimmed to meet the design requirements. tryout before customers will pursue the other parts together specimens When test mode in association with design engineers to model plant, structural design engineer on all accessories for mounting a single product inspection and exam, the appearance of failings in a single product, containing inspection and check the size of inspection, real equipment is to check all the parts in accordance with the tangible production assembly sequence for real equipment, identify the problem. all questions were listed, and the coordination model plant to determine the improvement of programs to improve the time and responsible for improvement, design companies and controversial issues mold factory has made the final by the customer judged to sign copies and discuss the results in triplicate to pay consumers, design firms and die plant were maintained to remain at the end, design updates to mode basis of the discussions drawings, plans to issue a prim change mode, change mode to mode part of the figure includes a detailed text illuminate the need to change parts of the 3D model drawings. 3D drawings required to mode part of the required red flagged. micromanager point to mode problems, not disregard.

; fourth, after the pilot sample
improved test mode will repeat the program can be tested, but this test mold the upper and lower shells and other exterior accessories can cook surface treatment (such as ID are apparent on the surface of artwork injection, over UV, oxidation, drawing, screen printing, electroplating, laser engraving) for further real equipment, real equipment is recognized if correct, you can arrange a trial flee. pilot can not be installed can be found a few problems found, the number of trial production is generally 50 to 100 units, arranged in accordance with the actual production of the assembly production lines, pilot customers in conjunction with the structure when design engineers to assembly plants, design engineers made it clear from the assembly sequence and precautions, assembly plant by the PE Engineer arrange the production line arrangement, each guide operator to determine the correct operating practices and criteria,Nike Air Max Light, engineers need the amount of pre-PE completion of each assembly station operating instructions. in the assembly plant for the assembly try to be summarize, the model plant materials have been affixed to the housing, the metal piece from the mold factory has also been hot melt onto the housing, the assembly plant at the peak of Load button on the housing, board, co-shell, locking screws, setup the lens, the final test, packaging on it.
when the pilot issues identified by the structural design engineer record, if you need to change modes, from structural design engineers diagram out the change mode, change mode to mode part of the figure includes a careful txt description, need to change the mode part of the 3D drawing. 3D drawing requirements change mode part of the required out of red VI. advertising suppliers to cultivate and follow up the progress and change the mode to mode results, change the mode after the completion of hunk production.

; fifth, production
after reiterated demonstration, modification, testing , modified, structural design engineer the results of hard work is about to come out, always the problems have been addressed before hunk, and if there is no problem, the process of production can do without the participation of design engineers, according to the new market conditions, the general price of 800 yuan left over mobile phone sales 5K, customers can regain the price, and then there are more orders, the customer may have earned. productions kick the market, a reflection of the market, customers may make some modifications, design engineers do the appropriate answer to it. see their mobile phone design hot in the market to buy, the kind of feel favor their babies complimented by others as exceedingly snug.
