Hauv cov txheej txheem ntawm kev tsim cov khoom siv hluav taws xob, PCB pov thawj yog qhov tseem ceeb txuas. Nrog rau kev nce qib ntawm cov thev naus laus zis thiab kev nce hauv kev xav tau ntawm kev lag luam, kev pabcuam PCB sai sai tuaj yeem txhim kho qhov nrawm ntawm cov khoom lag luam thiab kev sib tw. Yog li, PCB board ceev prototyping kev pabcuam suav nrog dab tsi?
Engineering xyuas cov kev pabcuam
Nyob rau theem pib ntawm PCB prototyping, engineering xyuas cov kev pabcuam yog qhov tseem ceeb. Engineering tshuaj xyuas cov kev pabcuam suav nrog cov kws tshaj lij engineers tshuaj xyuas cov qauv tsim kom ntseeg tau tias lawv ua tau raws li cov qauv tsim thiab cov kev cai tsim khoom. Los ntawm kev tsim qauv thiab kev tshuaj xyuas engineering thaum ntxov, kev ua yuam kev hauv kev tsim khoom tom ntej tuaj yeem raug txo qis, cov nqi txo, thiab kev loj hlob tag nrho luv luv.
Kev xaiv cov khoom siv thiab kev pabcuam kev yuav khoom
Kev xaiv cov khoom siv yog ib qho tseem ceeb txuas hauv PCB prototyping. Cov khoom siv hluav taws xob sib txawv muaj cov khoom siv sib txawv. Nws yog ib qho tsim nyog los xaiv cov khoom siv hauv paus tsim nyog, tooj liab foil thickness thiab txoj kev kho saum npoo raws li qhov tshwj xeeb daim ntawv thov scenario. Feem ntau cov substrates muaj xws li FR-4, txhuas substrates, thiab cov khoom siv siab. Rapid prototyping service tuam txhab uas muag feem ntau muab cov khoom muag ntawm ntau yam ntaub ntawv kom tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv.
Kev pabcuam tsim khoom
1. Kev hloov pauv: txheej txheej ntawm cov khoom siv photosensitive (xws li zaj duab xis qhuav lossis zaj duab xis ntub dej) ntawm cov ntawv ci tooj liab, tom qab ntawd siv UV teeb lossis laser los nthuav tawm cov qauv, thiab tom qab ntawd tshem tawm cov khoom tsis tsim nyog los ntawm txoj kev loj hlob.
2. Etching: Tshem tawm cov ntawv xov tooj ntau dhau los ntawm kev siv tshuaj lom neeg lossis cov tshuab plasma etching, tawm hauv cov qauv Circuit Court nkaus xwb.
3. Drilling thiab plating: Drilling ntau yam yuav tsum tau los ntawm lub qhov thiab qhov muag tsis pom / faus qhov ntawm lub rooj tsavxwm, thiab tom qab ntawd ua electroplating los xyuas kom meej qhov conductivity ntawm lub qhov phab ntsa.
4. Lamination thiab lamination: Rau ntau txheej boards, txhua txheej ntawm Circuit Court boards yuav tsum tau glued ua ke nrog resin thiab nias nyob rau hauv kub thiab siab.
5. Kev kho deg: txhawm rau txhim kho weldability thiab tiv thaiv oxidation, kev kho deg feem ntau ua. Cov kev kho mob feem ntau muaj xws li HASL (kub cua leveling), ENIG (kub plating) thiab OSP (organic txheej tiv thaiv).
kev kho mob thiab tshuaj xyuas
1. Kev ntsuas kev ua tau zoo: Siv lub davhlau ya davhlau ya davhlau ya davhlau los yog ntsuas qhov ntsuas hluav taws xob los ntsuas txhua qhov hluav taws xob sib txuas ntawm lub rooj tsav xwm Circuit Court kom ntseeg tau tias txuas ntxiv thiab rwb thaiv tsev raws li cov qauv tsim.
2. Kev tshuaj xyuas qhov tshwm sim: Nrog kev pab los ntawm lub tshuab tsom iav lossis cov khoom siv kho qhov muag tsis siv neeg (AOI), nruj me ntsis tshuaj xyuas cov tsos ntawm PCB pawg thawj coj saib kom pom thiab kho cov teeb meem uas yuav cuam tshuam rau kev ua haujlwm.
3. Kev sim ua haujlwm: Qee qhov kev sib tw ntau dua yuav tsum tau sim ua haujlwm kom simulate qhov chaw siv tiag tiag thiab sim seb lawv puas ua haujlwm tau raws li qhov xav tau.
Kev ntim khoom thiab kev pabcuam shipping
PCB boards uas dhau qhov kev sim thiab tshuaj xyuas yuav tsum tau ntim kom zoo kom tsis txhob muaj kev puas tsuaj thaum thauj. Cov ntim khoom muab los ntawm cov kev pabcuam sai sai feem ntau suav nrog cov ntim tshuaj tiv thaiv zoo li qub, ntim pov thawj poob siab, thiab ntim dej tsis zoo. Tom qab ntim tiav lawm, lub tuam txhab kev pabcuam pov thawj yuav xa cov khoom sai sai rau cov neeg siv khoom los ntawm kev xa khoom xa tuaj lossis kev pabcuam tshwjxeeb kom ntseeg tau tias kev tshawb fawb thiab kev loj hlob tsis cuam tshuam.
Kev pab txhawb nqa thiab kev pab cuam tom qab muag
Kev pabcuam PCB sai sai tsis yog tsuas yog muab kev tsim khoom thiab kev tsim khoom, tab sis kuj suav nrog kev pabcuam kev pabcuam thiab kev pabcuam tomqab muag. Thaum ntsib teeb meem lossis tsis paub tseeb thaum lub sijhawm tsim qauv, cov neeg siv khoom tuaj yeem tiv tauj nrog pab pawg txhawb nqa txhua lub sijhawm kom tau txais kev cob qhia thiab cov lus qhia. Txawm tias tom qab cov khoom xa tuaj, yog tias cov neeg siv khoom ntsib teeb meem zoo lossis xav tau kev txhim kho ntxiv, pab pawg pab pawg tom qab muag yuav teb sai sai thiab daws lawv, ua kom cov neeg siv khoom txaus siab thiab ntseeg siab.
PCB board ceev prototyping kev pabcuam npog ntau yam los ntawm kev tshuaj xyuas qhov project, xaiv cov khoom siv, kev tsim khoom thiab kev tsim khoom rau kev kuaj, ntim, xa khoom thiab kev pabcuam tomqab muag. Kev ua tau zoo thiab kev sib txuas ntawm txhua qhov txuas tsis tuaj yeem tsuas yog txhim kho R & D efficiency, tab sis kuj txo cov nqi tsim khoom thiab txhim kho cov khoom zoo.
