Lub sij hawm hloov, tus qauv tau nce zuj zus, thiab tam sim no kev lag luam ntawm qee qhov kev lag luam zoo PCB tau nthuav dav heev, ntau lub tuam txhab muab PCB pawg thawj coj saib, SMT thaj, BOM thiab lwm yam kev pabcuam, uas PCB pawg thawj coj kuj suav nrog FPC board hloov tau thiab PCBA. PCBA yog "cov neeg paub qub", yuav luag ntev npaum li nws cuam tshuam nrog PCB tuaj yeem pom PCBA daim duab, hnub no peb yuav nthuav qhia "cov qhua nquag" uas feem ntau tshwm sim.
PCBA yog cov ntawv luv ntawm English Printed Circuit Board + Sib dhos, uas yog hais tias, PCB khoob board los ntawm SMT ntawm daim, los yog los ntawm DIP plug-in tag nrho cov txheej txheem, hu ua PCBA. Qhov no yog ib txoj kev sau ntawv uas siv nyob rau hauv Suav teb, thiab cov txheej txheem sau ntawv nyob rau hauv cov teb chaws Europe thiab lub tebchaws United States yog PCB 'A, ntxiv rau "'", uas yog hu ua lub official idiom.
Thaum kawg ntawm xyoo 1990, thaum muaj ntau txheej txheej luam tawm Circuit Board tau npaj tseg, cov txheej txheem txheej txheej luam tawm Circuit Board kuj tau raug tsim los ua ntau tus lej, txog tam sim no. Nws yog ib qho tseem ceeb los tsim kom muaj lub tswv yim zoo rau cov khoom loj, siab ceev luam tawm Circuit Board sib dhos (PCBA) kom ntseeg tau tias kev ua tau zoo thiab ua haujlwm nrog tus tsim. Ntxiv nrog rau kev tsim kho thiab kev sim ntawm cov rooj sib tham nyuaj no, cov nyiaj tau nqis peev hauv cov khoom siv hluav taws xob ib leeg tuaj yeem siab - txog li $ 25,000 thaum kawg kuaj ib chav. Vim tias tus nqi siab no, nrhiav thiab kho cov teeb meem sib dhos yog ib kauj ruam tseem ceeb tshaj tam sim no dua li yav dhau los.
Printed circuit board, tseem hu ua board circuit board, printed circuit board, feem ntau siv cov lus Askiv luv luv PCB, yog cov khoom siv hluav taws xob tseem ceeb, yog lub cev txhawb nqa ntawm cov khoom siv hluav taws xob, yog cov chaw muab khoom siv hluav taws xob sib txuas. Vim tias nws yog tsim los ntawm kev siv tshuab luam ntawv hluav taws xob, nws hu ua "printed" Circuit Board. Hauv cov ntsiab lus yooj yim, PCBA tuaj yeem yog cov txheej txheem ua haujlwm ntawm SMT thaj ua haujlwm, DIP plug-in processing thiab PCBA kuaj, hu ua PCBA.
Feem ntau tsis zoo li kev nkag siab tseeb, puas muaj kev xav ntawm PCBA niaj hnub no?
