one handset shell material namely adapt warmhearted abs + pc, PC + What are advantages and drawbacks of the application of glass?.
broader application of mobile phone shell material is PC + ABS, plastic plus glass fiber's main role namely to strengthen the plastic strength. PC + glass is the same reason barely also tin amend the competence of PC anti-stress materials, plastic components to rectify the flatness.
Disadvantages: injection of liquidity even aggravate plastic surface namely easy to float fiber,add the difficulty plus mold injection molding requirements. Injection of liquidity because the PC itself backward.

2 What are the materials for plating? which material namely never suitable for plating? any failings
plating must 1st distinguish between water plating alternatively vacuum plating, coating materials,quite little common water, electroplating grade ABS is the maximum commonly acclimate PP, PE, POM, PC plus additional material never suitable for water-plating. Because these surface particles athletic poor, poor adhesion. If you do go through a special water-plating process.
vacuum plating of plastic materials to adapt to a broad range: PC, ABS, PMMA, PC + ABS, PET,plus so aboard

3 After the shell plating choose meantime to expenditure attention to forever those areas?
generally do never do all the water backward the shell plating, because the water longing affect the whole-plated RF performance,namely never conducive to anti-static,barely also not conducive to the architecture because the water longing cause plating pieces of hard plastic breakable
If full-plating to the attention of:
1 vacuum plating, preferably made non-conductive vacuum plating (NCVM),merely the spent namely lofty
2 in order to decrease costs, water plating, the internal structure of the insulation to spray ink.

How do mobile phone companies project management

science namely a project management aboard project funding,period manpower, products, resources, control of management science. This management approximate innovation in the late 1950s the United States,and in some areas of application, with very comely results. World-renowned management consultant foresaw the U.S. pmi, project management ambition convert or has become a popular economic epoch to convert the world's maximum vitality plus the maximum common ministry core sector management prototype,equitable favor in affair management, which has convert a trend.

in the fashionable market conditions, China's domestic mobile phone enterprises are facing a changing market environment factors: the increasingly sophisticated consumer market is leading to competition rules convert difficult to grasp,barely the changes in the rules of competition are navigate to the sustainable development of mobile phone companies face a growing threat; mobile phone R & D technology namely becoming the core of forever of its complexity is increasingly becoming the source of risk; phone features high-tech equitable as the diversity plus correction prefer all additional fields are changing the business itself, communication network namely not longer a purely technical tool,alternatively a fashionable trading patterns,merely a new way of life plus economic patterns,affect social values ​​and affair conduct of operations; corporate policies and systems environment of annexed uncertainty; employees more economically rational behavior and short-term, traditional salary plus bonus agitation system not longer encounter the staff, they lack to obtain more work autonomy, a sense of belonging, a sense of fulfilment and development opportunities fewer supervision and command,plus enterprises have higher expectations. In the mobile phone industry,many businesses have started mobile phone he migrated from OEM to independent research plus development. Purpose namely to continue to introduce successful fashionable products longing grant businesses to remain viable, the development of the market of. Then the face of forever the circumstances of this scientific project management solution has convert a fundamental building-related conflicts plus to improve the brand and consultant the healthy development of the engine affair

phone overall status of project management

the past, because our country is insufficient emphasis aboard project management, resulting in a lot of duration manpower plus additional aspects of waste, seriously hampered the process of modernization in China, mobile phone industry of special note Industry project management skill, expertise plus mobile phones that know how to have a professional project management processes plus a lack of talent Difficult to discover the mobile phone industry to understand the professional experience of project management specialists have so many mobile phone industry companies, have a agreeable project adequate funding,good crew but because there is no agreeable project management,and makes some companies into the hardships even to near down the project management of opener personnel ought not only have a deep understanding of the industry,meanwhile on the market, personnel management has a strong rein capacity
It is understood that China's mobile industry realize the basic objectives of the project alternatively the relatively small proportion of investment projects, accounting as a absolute failure of a decisive percentage of its one of the bishop project management work namely not done , ie not doing initiating, planning, execution, control,finishing five project management process, several mobile phone industry did never do a good-looking job integrating management scope management,period management,cost management, quality management, human resources management, communication management,risk management plus acquisition management system management, management coordination, usually a mobile phone project has several cardinal line:
one market research / pre-research / selection / spent accounting / UI and MMI diagram / package chart and production of such materials / marketing agenda to improve / market ready;
2 ID design / structural design / affair negotiations / model / nail mode;
three ID palm making / architecture palm;
4,circuit chart and schematic Review / PCB layout / PCB system board / Engineering Validation / movement embark / chip / driver software debugging / pilot / network / batch;
five schematic graph and electronic building of materials determined to begin / accessories example application part preparation for snuggle and trial making

only as mobile project management, its project management is the core of quality management and process management. Each implementation of the project are aimed by mobile phone to achieve affair goals,barely the application of popular technology alone namely never capable to completely solve the problem, the project's successful implementation of any phone in the corporation are important to acquaint some adapted changes. Only through applicable project management,can aid companies join revenue. Reduce costs,amend service quality,plus conquer market opportunities or to gain a complete project management success.
mobile project management project management,prevalent failings in
phone industry has attracted spacious attention, project management has convert a business in the maximum basic order management process, more plus more companies began to accompany importance to the introduction of project management personnel,many of the company's project managers are everywhere aboard the yuan every month salary, which from the side of the current mobile project management development. But, more importantly, with the mobile phone market continues to expand, the mobile phone industry continues to amplify market division of luxury,compartment phone in the substantial implementation process, project management, there are much problems:
First, the actual implementation process of the project constantly the phenomenon is never explicit division of functions. First, the personnel division of powers is not clear; second division of the department's responsibilities namely unreasonable; Third, the functions of project management itself namely not explicit The company's senior leadership are usually defined as a project management administrative responsible for administrate the operation of other departments. Its role never only can never guide the project crew to utensil the project,barely sometimes unnecessarily additional the workload,and even misled the engineers decisions.

Second, the project decision-making system namely unreasonable. Many small and media enterprises in the mobile phone,much of the opener project decision points are to take one decision making. For example, some integrators customers, ID design transformed the manager of a person's art appreciation products, stunned to impose their ideas or ID's project manager, engineers work in technology, marketing has become a natural . Hardware selection has become a person's accomplishments, from the engineer's point of outlook they are more concerned nearly the performance of the components,meantime the cost relatively micro consideration has.
Furthermore, project management platform namely not faultless Mobile project management associated to project, ID, MD, software development, hardware donation and mold testing,plus so chapter of a array of activities. Many among them is the need to cross-functional organization. For example, ID is designed to take into account the draft of MD,never impartial reckon of it as a go of craft it have to be a use merit of the goods; software chart barely also take into account the hardware logic design Different projects a lot of resources can be shared, so it needs to project management to achieve Mobile R & D organization namely not a lack of enterprise project management tools,merely they lack a sound project management processes, resulting in project management is no chapter could be base not formal; revise departments interface namely never explicit there are passing phenomenon; not effective Sourcing Management Plan, we are convert a member of a happening negotiation.

In counting some enterprises, the cardinal person in charge of project management plus associated personnel are never skilled with their happening lack of professional knowledge plus advocate China's servant mobile phone brand is still at a inexpensive class of project management, quality management, management level namely relatively cheap The main problem is not in the project, a comprehensive and systematic use of project management methods, there namely not specialization. According to lacking statistics,however the numeral of folk busy in project management has reached hundreds of thousands,merely most of these folk busy in part-time or project management transformation. They experience less management class namely never lofty Or namely the faultless technology,merely lack of management capability,alternatively to understand the additional hand, the management,barely the lack of professional understanding of the industry. In any case,ambition outcome in company asset manpower,plus period to waste even a direct result of failure of the project, of lesson in the actual work there are various deficiencies,barely we must go from the source sound, to specification, to be innovative.


Rubber opener production process of rubber to suppress description
preparation → → Paint → → punching → laser engraving this production ambition be packed
1st production of every process,annotate in detail:

one preparation: in truth,namely to be made of rubber blocks and some of the aboriginal ingredients (mainly with pigment plus additional agencies cooperate fully with uniform plus then extruded into nickel,afterwards cut into strips of rubber needed to be adapt as after-suppression.


two Rubber repression: the road merely the main process,deem it ambition out of an chance whether the rubber is quite skinny alternatively lane it namely feasible to hack while removed (may be due to rubber wall likewise thin,narrow high mold temperature was about 100 ℃, the rubber is likewise soft,not strong enough) see 2024's buzzer Fan class seals the outer verge is an instance; merely also a flash ticketing program namely not followed rushed to) as the form of this flash is to can not afford,


three painting: This namely a problem , because that advent merely the crucial point,deem it namely waste, there are generally two spray draw,different colors for use later the laser engraving.appealing to spray finished come back backward a program

four stamping: the flash is never rushing to tear off, leaving the lusted opener ok,only in the Road
ticketing process ambition entire be a flash ah, ah this namely never allowed to do, the mutual arbitrage of the huge side and direct brim namely never flash,afterwards flash namely what will generate it?namely too small arbitrage side will produce more small?listened namely never fewer than 0.3mm not confirmed) which I think may be of engineers in the design of our bodies while the rubber chapter to the brink of the arbitrage useful as stamping Yeah, well, to the next an in process it!
laser engraving: Laser engraving namely the key is to amend the flat, in mutual the system with a agreeable location,afterwards the opener laser engraved out of the height layer of draw tune out the opener words to the on such as digit keys,is transparent; whether sculptured out of two layers of draw ground only, leaving a floor such as ok answer key plus open the opener is a floor of draw is ruddy there namely the blue .
production packaging: This is naught that is a agreeable package flasks plus shipping


Mobile architecture a framework points to memorandum
common principles: first the line structure Omo,steps legibility,afterwards noodles,plus finally dismantled lines plus elaborate lines. Skeleton must be easy to change

one have to never refer to import from CAD in the lines, scanning lines used only for reference. Scan line to be very near to
imported lines,if the architecture does need to be adjusted,first consult with the ID.
Second,make plans to take the first few features of the machine width,breadth plus height of the lines flagged.
three,tin never arise gray not enhanced) size.
Fourth, the size of an decimal space whether you must two decimal places, to 0.05 as the bottom
Fifth, do not venture to fabricate spline Omo, Omo too do never offer to construct the four corner arbitrage arbitrage with oval,
standard sizes from either ends of the point mark
six,while the 1st scan line scan dismantled lines,plus afterwards describe the details of parts in the line, details of the line as a reference line with a dismantled
to standard size.
seven parts of a complete line drawing plus afterwards depict the details of the subsequently chapter should never jump scanning lines.
eight opener areas 1st described the OK button, OK button to brand the X-axis dimension, the additional key tin only refer to the OK button median standard size.
Y-axis is referenced.
nine, skeleton in the AB case plus battery cover parting drawn to the surface amongst the Y-axis that is too drawn.
ten, described the common steps to the first scan line A shell lines - key - B shell - the power cell cover - side.


FPC knowledge schooling

one FPC Profile:
we always know, FPC has been warmly adapt in mobile phones,activity an important role, it has a common PCB do never have the advantage,tin be accustom to connect the LCD plus the motherboard; side buttons plus motherboard connections.
FPC amenable printed circuit embark that is (Flexible Printed Circuit Board), with amenable insulation material (polyester or polyimide membrane made of published circumference rigid printed circumference boards with many never have the advantage. It is free to bend airing folding,tin be arranged in accordance with any requirements of the spatial layout,sac louis vuitton,and any behavior in three-dimensional space plus scale to realize the component assembly plus integration of cable linkage This diversity of circuit can never only be curved and light weight, small size, heat dissipation, easy to install, interconnect technology to crash through the traditional concept.

FPC too has good-looking heat resistance plus weldability,plus even easy to install, comprehensive and inexpensive cost integrated hardware plus software design has to a crucial extent,make up the flexible substrate in the factor slightly less than the carrying capability FPC can behalf greatly reduced the volume of electronic products, electronic products applied to high-density, small size,lofty reliability and direction of development. Therefore, FPC in the aerospace,naval mobile communications, portable computers,computer peripherals, PDA, digital cameras and other areas alternatively products have been warmhearted used
lesson FPC too has much drawbacks, such as mechanical strength namely small, easy to crack; process blueprint problems; the possibility of re-processing of the low; inspection difficult; not a unattended carry heavier parts; prone to fold,activity injuries; lofty priced of the production and so on But these shortcomings are distant less than the benefits it has brought us benefits,accordingly it has been in the electronics plus communications industry increasing attention plus a spacious range of applications.

two FPC material:
FPC mainly consists of four parts: CCL (Copper Film), the protection membrane (Cover Film), reinforcing layer (PI Stiffener Film), adhesive layer ( Adhesive Sheet).
Materials associated to the body as follows:
bronze copper): copper plus coiled copper base is divided into two (commonly used mobile FPC rolled copper foil).
common thickness as 1oz and 1/2oz (1/2oz bronze thickness = 0.7 mil = 0.018mm.).
substrate layer base film): commonly acclimate material for PI (polyimide). Common thickness of 1mil plus 1/2mil two.
adhesive: thickness along to buyer request, usually 0.5mil epoxy thermosetting adhesive.
protection film: surface insulation. Commonly acclimate material as PI (polyimide). Common thickness of 1mil plus 1/2mil.
reinforcing film: FPC reinforcing the mechanical strength, easy surface mounting operations. Common thickness 5mil and 9mil.
from the form of paper: to avert adhesive buildup of alien matter ahead the pressing, easy to point operations.
reinforcement materials: common namely the PI safeguarding ground reinforcement), FR4 shielding floor reinforced),steel
between layers of plastic: 1mil thermosetting epoxy paste
Note: 1mil = 1/1000in = 0.025mm. mil,also known as mil, mils (thousandths of an inch). 1mm = 40mil.
forever,almost the thickness of every alone panel is: 0.5mil protection layer +0.5 mil thermosetting plastic +1 / 2oz bronze +0.five mil thermosetting plastic +0.five mil substrate = two.7mil = 0.0675mm.

three FPC structure:
FPC has alone double and multilayer divided. Double-sided, multilayer published circuit boards amongst the surface and the interior conductor is gold
realize inner and outer circuit of the electrical connection General we mean that only a ground of single-sided bronze foil,only in fact it is a absolute of five layers (including the tape,not reinforcing nickel double-panel 9-layer (conventional). The panel is generally the nave floor of the double bottom membrane,either sides have two copper
following two figures are single-sided FPC sections and dual-panel cross-section diagram:


The 1st chapter of the process
mobile structure: chassis types: plastic shell, plastic neat plastic power cell cover
an material:
an commonly adapt in GE's PC + ABS-1200HF plus electroplating grade ABS plastic material. PC + ABS This material is characterized by toughness, density
seal namely agreeable lofty mechanical strength, chemical resistance, texture,lofty mobility, easy-to-injection molding; plating grade ABS PC + ABS strength ratio is cheap mainly used in electroplating decorations. Now there is a GE of PC + ABS (Model 1300HF) either spraying,merely too plating.
two there are other materials that can be used: PC, glass fiber reinforced PC + ABS, LG and Samsung PC + ABS.
Second, the surface treatment: painting + UV, plating,screen typography etch, attached leather
one spraying:
1 materials, including draw UV (plus a hard surface, the protective fulfill thinner. Factory alternatively draw forward to buyer demand for draw forming a variety of color schemes. Hand spray and spray methods are spraying machine (automatic spraying line), with hand spray is mainly used as proofing to the consumer to confirm the color contrive to note that the color accomplish of hand-spray sprayed with machine there namely color. Spraying machine namely in production use. Automatic spraying line is generally between 80-400 meters long (two spray painted two alternatively three three-coat spray),production capability at 5000-200000 pieces / rings.
two Color Control:
A, dilution percent of draw paint thickness, UV's Guangya degrees (which namely usually a fraction that eliminate) the conflict of the color attain namely relatively tremendous impact
;
B, the clash of material --- light-colored paint on the principle of material with a light,black draw with a black material;
C, some special colors have to be two vary spray primer,another UV, in order to reflect the fulfill of appealing color,
such as red usually the 1st spray silver draw,afterwards sprayed ruddy draw
D, light-colored paint spray draw problems --- light shading rate namely quite inexpensive directly onto the chassis,afterwards the persona will be revealed to the material which affect the color effects (especially the African material),plus easy to so amongst the reflected light aboard the motherboard the internal structure of the shadow; so light-colored draw to be sprayed double a common primer
3 wrong spraying problem: the larger the area leveling --- spraying, leveling the worse; Shen point --- dust (Yen
alter color draw aboard the amplification of alter failings such as high-gloss African particularly apparent); product fuel --- plus architecture
2 plating: (mainly for decorative plated parts water)
1 colors are generally shine silver plating,gun color. For mobile phone shell, the gun color easy to wear plus slit scratches, pollution plus much of its processing. In counting the large structural parts of the plating on the compartment phone indicator interference is very enormous need to take accustomed measures to avoid them.
two the realization of bright matte --- cordless mold. Colors are shine silver,pistol color, pearl color. Surface is generally bright and dark silver color pistol matte silver plus pearls can be color (looks favor a white mist
3 undesirable phenomena: --- Shen point impurities; resistance plated fuel accumulation affect the assembly
Part II: metal structure --- stainless iron aluminum neat nickel plate neat
I. stainless iron aluminum trim pieces: the metal mold press forming, surface treatment process are: surface mechanical drawing (striped); overall matte surface oxide formation as aluminum),and the black color of the metal character; surface plating bright,dark gold - lofty cost need for the record); surface corrosion font diagram (stainless steel lofty cost,cheap efficiency); surface laser laser engraving font chart (stainless iron Omo, a small surface can be). Assembly process: hot thaw adhesive, structural strengthening (such as increasing the buckle-bit).

Second, nickel plate trim:
one normal thickness of the nickel nickel 0.16-0.25mm:
1 process: production of copper mold (ie,louis vuitton sac, motherboard,by to the size of one * one 1 * 2,one * 4 size) --- Ni block
pond in the electrolysis electrolysis, nickel ions attached to the motherboard surface --- the 1st an with a strip to form the lusted vogue of nickel
template while the motherboard is not longer the 1st an to use --- Ni --- template plus afterwards aesthetic nickel ions into the electrolytic cell adsorption aboard the surface,then peel the formation of a second nickel-template --- Repeat the previous step the formation of colossal mass making of nickel template --- --- plating the product surface to realize a diversity of effects shine silver, gold) --- red type product size, some small, decorative pieces, such as handset, the surface shell decorative pieces)
2 Capacity: a electrolytic cell can be released more than 30 pieces of nickel templates,each can generate dozens of nickel plate; nickel ions attached
time 2-3 hours, plating phase of five - for 10 minutes.
2 Ni skinny layer 0.05-0.08mm:
process: the special ink accustom in printing a stainless iron plate into the electrolytic compartment architecture plus fashion --- --- --- plating nickel ions attached to the molding - - production (equivalent to the thickness of the ink thickness production
Part III: Key
a, P + R keys:
numeric keys, function keys, navigation keys, OK key
Material: The cardinal a PC and silicone
process:
one spray + laser engraving + UV: spray twice handbook --- font color, surface finish --- color
two electroplating (plating water) ; 3 plating + laser engraving;
four the back of the shade printing: lofty quality requirements, especially aboard the quality of color printing colossal surface treatment more tough some colors tin augment the surface failings such as Black (NP313).

Second, the metal keys:
one material: bronze low-temperature fluid silicone, AB paste PET membrane
2 process: bronze processing (0.2mm bronze --- Film Exposure --- --- --- Etching --- developing the first plating (mainly to safeguard the surface from scratching) --- Dispensing (AB Glue) --- grinding machine (grinding, polishing, CD pattern processing ) --- second plating forward to alter requirements for surface plating colors) --- the surface of metal draw (UV)
three process characteristics:
1 single-layer silicon thickness of 0.05mm , conductive column 0.25mm, PET0.075mm, the purpose is to assist the use of PET screen;
two 5 blind not dispensing opener numeral directly from the silicone molding;
3 with the purpose of bronze comely ductility, easy-to-die-casting;
4 non-performing rate of virtually 50%;
5 Testing requirements: wear-resistant,lofty temperature, artificial sweat,an hundred cells
6 silicone Mold: three nickel mold, the laminate tin be freely removed. Processing,1st printed in the lusted color on the PET results, the fluid silicone aboard the PET, the upper and lower molded cast sheet; open the upper and lower mold, silicone mold with PET is attached to,and afterwards put the mold in layers Liquid silicone,and afterwards on the lower mold dead casting.

Third, the ultra-thin P + R keys:
one PC is a whole piece tear some of the general type, the main process namely the back of the shade and the back of the plating; the back of the plating metal buttons tin be made into the effect;
two PC parts are not replaced with acrylic because acrylic hardness,adviser key linkage;
3 non-performing rate: PC cut a decisive degree of hardship easy to play glitch, its hardening poor plating higher;
four PC parts tin be injection molding process,deserving to the common requirements of a thickness of 0.4mm, high-speed injection molding machine to be processed.
5 silicone parts: two layers of silica gel, a floor of TPU (TPU namely located between two layers of silica, the main role is to maintain the opener namely not deformed, easy-to-screen)
Part IV: large-screen lens lens
--- cutting, injection molding, IML, IMD;
Material: Acrylic (PMMA) plus PC
camera lens --- glass,cut and aesthetic molding

one cutting the lens:
1 the surface treatment process:
an electroplating (plating back real): real-plated rear lower than the water, plating adhesion, easy to clothe barely it can never be deposited aboard the back of the
easy to dress Real-plated metal plus non-metallic materials, metal color silver and pistols are generally two varieties of color, brightness can be adjusted; non-metallic colors tin be formed more, technology is relatively perplexing especially to use the spectrometer for spectral analysis, According to the wavelength of light filtered light in order to achieve the desired color accomplish The effect of change processing costs are also vary colors.
two Hard surface: the lens into the addition of special additives in the soaking syrup,plus hard after the transmittance of the lens can be additional 1-2%.
three shade
4 Post Laser Paper

two processing technology:
lens material originally tear sheet full sheet as plating and afterwards cut type,plus afterwards the fade-plated. Do never vanish while the fade-plated coating a floor of special ink aboard the shade region to protect faded back plating,along to the needs of revise colors in the back of the screen to form a vary pattern effects.
Second, the injection lens: the lens namely mainly accustom as abnormal mainstream such as arc plus class with the lens, the lens surface treatment plus cutting similar.
three, IML and IMD lenses:
cardinal requirements for a special assembly process of the lens, such as the lens to be tight to the chassis amongst the hot melt,hot melt because the lens aboard the back of a column,never the back of the shade plus plating, surface treatment can only be affirmative
one IML lens: a PET canvas or membrane screen printing to form the lusted plating surface effect --- the membrane into the mold - plastic injection molding --- Acrylic and acrylic membranes in one plating plus printing middle located between the two.
lofty failing rate of this process, mainly because the process ambition generate bubbles; acrylic and film not tightly integrated,skin off warped.
two IMD lens: IML process similar to the lens, the last two steps are different: film plus ambition be separated from acrylic, acrylic media
attached to the surface,must be over UV protection.


Ten mobile phone chart drawing elements

general principle: do structural ideas ought be explicit we have to do the characteristics correction as the henceforth to prepare plans plus regeneration characteristics.
an If the demolition of chapter features as feasible from the 1st side boundary COPY, COPY will never face every additional for parts dismantling (small parts namely feasible Try never to cross-reference between parts likewise much, in order to avert regeneration failure.
two All the parts to the assembly at default every COPY line when the surface alternatively preferably by an outer duplicate to COPY.
three.amongst the external surface to again chapter of the replication time be sure to bring an end to and afterwards COPY COPY of the surface.
4 do snap and screw column, only the jaws etc.should be coupled with.
five.firm to use any electronic components while the two parts come with a firm should go together otherwise it is easy to forget. Such as the MIC.
six sketched with reference to election phase Priority face,try never to prefer sides do reference.
seven.2001 version replaces fewer commands,and so tin never redefine the offset command, unless the modification of this surface namely no longer used other references.
8 do the map, with enormous surface can never refer to small parts, only small parts to tremendous parts reference charting
9.attempt not to bound mapping that namely here to do a tread,afterwards leap to do repeatedly step
10. If you absence to refer to drawing board stack you can amass the components in the related to the parts graph in the COPY,then where do the characteristics of the parts. If the pile to discourage the replacement of embark characteristics caused at the failure,louis vuitton portefeuille,meantime you tin sketch a reference to cancel reference to the motherboard,and afterwards standard size
