Printed Circuit Board sib dhos yog ib qho ntawm cov kauj ruam tseem ceeb hauv kev tsim cov khoom siv hluav taws xob. Nws npog ntau theem los ntawm kev tsim lub rooj tsavxwm mus rau cov khoom sib txuas thiab kev sim zaum kawg. Hauv tsab xov xwm no, peb yuav nthuav dav tag nrho cov txheej txheem ntawm PCBA fabrication kom nkag siab zoo dua cov txheej txheem tsim khoom.
Theem 1: Board Design
Thawj kauj ruam hauv kev ua PCBA yog kev tsim hluav taws xob hluav taws xob. Hauv theem no, cov kws tshaj lij hluav taws xob siv PCB tsim software los tsim cov duab kos duab thiab schematics. Cov duab kos no suav nrog ntau yam khoom sib txuas, kev sib txuas, kev teeb tsa thiab kev xaim ntawm lub rooj tsav xwm hauv Circuit Court. Cov neeg tsim qauv yuav tsum xav txog qhov loj, zoo li, tus naj npawb ntawm cov khaubncaws sab nraud povtseg, txheej kev sib txuas thiab cov khoom siv tso rau ntawm lub rooj tsavxwm. Tsis tas li ntawd, lawv yuav tsum ua raws li cov qauv tsim thiab cov qauv tsim los xyuas kom meej tias qhov kawg PCB tuaj yeem ua tau raws li kev ua tau zoo, kev ntseeg siab thiab kev tsim khoom.
Kauj Ruam 2: Kev npaj raw khoom
Thaum lub Circuit Court board tsim tiav, cov kauj ruam tom ntej yog los npaj cov khoom siv raw. Qhov no suav nrog:
PCB substrate: feem ntau yog ua los ntawm iav fiber ntau cov khoom sib xyaw thiab tuaj yeem ua ib sab, ob sab lossis ntau txheej. Cov khoom siv thiab tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm substrate yog nyob ntawm tus qauv tsim.
Cov khoom siv hluav taws xob: qhov no suav nrog ntau yam chips, resistors, capacitors, inductors, diodes, thiab lwm yam.
Solder: Cov hlau lead-dawb feem ntau yog siv los ua kom tau raws li kev cai ib puag ncig.
PCB Plating Materials: Plating cov ntaub ntawv siv los coated PCB pads.
Lwm cov ntaub ntawv pabcuam: xws li cov tshuaj txhuam hniav, cov khoom siv PCB, cov khoom ntim, thiab lwm yam.
Stage 3: PCB Manufacturing
PCB manufacturing yog ib qho ntawm cov theem tseem ceeb ntawm kev ua PCB. Cov txheej txheem no suav nrog:
Printing: Luam cov kab qauv ntawm daim duab kos rau ntawm PCB substrate.
Etching: siv cov txheej txheem tshuaj etching kom tshem tawm cov txheej txheem tooj liab uas tsis xav tau, tawm hauv cov qauv uas xav tau.
Drilling: Qhov yog drilled rau hauv PCB rau mounting perforated Cheebtsam thiab connectors.
Plating: Txheej cov qhov hauv PCB nrog cov khoom siv hluav taws xob los ntawm cov txheej txheem plating kom ntseeg tau tias kev sib txuas hluav taws xob.
Pad Txheej: Siv cov nplaum rau PCB cov ntaub qhwv rau cov khoom txuas ntxiv tom ntej.
Theem 4: Component Mounting
Component mounting yog txheej txheem ntawm kev txhim kho cov khoom siv hluav taws xob rau hauv PCB. Muaj ob lub ntsiab mounting txheej txheem:
Surface Mount Technology (SMT): Cov txheej txheem no suav nrog cov khoom txuas ncaj qha mus rau saum npoo ntawm PCB. Cov khoom, uas feem ntau yog me me, raug kho rau PCB los ntawm kev muab tshuaj txhuam thiab tom qab ntawd soldered hauv qhov cub.
Plug-in thev naus laus zis (THT): Cov thev naus laus zis no suav nrog kev ntxig cov pins ntawm cov khoom mus rau hauv qhov dhau ntawm PCB thiab tom qab ntawd muab lawv tso rau hauv qhov chaw.
Cheebtsam mounting feem ntau yog ua los ntawm kev siv cov khoom siv tsis siv neeg xws li cov tshuab tso, yoj vuam tshuab thiab cov cua kub reflow ncu. Cov cuab yeej no ua kom ntseeg tau tias cov khoom siv tau raug muab tso rau hauv thiab soldered rau PCB.
Theem 5: Kev Ntsuas thiab Kev Tswj Xyuas Zoo
Cov kauj ruam tom ntej hauv kev ua PCBA yog kev sim thiab kev tswj kom zoo. Qhov no suav nrog:
Kev sim ua haujlwm: xyuas kom lub rooj tsavxwm ua haujlwm rau cov lus qhia tshwj xeeb, kuaj xyuas cov khoom ua haujlwm los ntawm kev siv cov khoom siv hluav taws xob tsim nyog thiab cov teeb liab.
Kev tshuaj xyuas qhov muag: Siv los txheeb xyuas qhov chaw ua haujlwm, polarity thiab solder zoo.
X-ray Inspection: Siv los txheeb xyuas cov pob qij txha thiab kev sib txuas sab hauv ntawm cov khoom, tshwj xeeb tshaj yog cov pob khoom xws li BGA (Ball Grid Array).
Kev ntsuas cua sov: Ntsuas kev ua haujlwm thermal thiab kev tswj xyuas thermal los ntawm kev saib xyuas qhov kub thiab txias ntawm PCB.
Kev Ntsuas Hluav Taws Xob: suav nrog ICT (Inverse Cling Test) thiab FCT (Final Test) kom ntseeg tau tias hluav taws xob ua haujlwm ntawm lub rooj tsavxwm.
Cov Ntaub Ntawv Zoo: Cov ntaub ntawv sau tseg thiab txheeb xyuas cov txheej txheem tsim khoom thiab kev sim ntawm txhua lub rooj tsav xwm hauv Circuit Court kom tswj tau qhov zoo.
Theem 6: Ntim thiab xa khoom
Thaum cov boards tau dhau los tswj kev ua tau zoo thiab muaj nyob rau hauv specification, lawv tau ntim. Qhov no feem ntau yog muab cov PCBs tso rau hauv lub hnab los tiv thaiv zoo li qub thiab ua raws li qhov tsim nyog ceev faj thaum thauj los xyuas kom cov laug cam mus txog lawv qhov chaw nyab xeeb. Cov PCBs tuaj yeem xa mus rau qhov kawg khoom sib dhos kab lossis rau cov neeg siv khoom.
