1.What yog lub PCB?
PCB = luam Circuit Court board ; Suav lub npe, hu ua luam hluav taws xob board, yog tseem hu ua luam Circuit Court board, uas yog ib qho tseem ceeb hluav taws xob tivthaiv. Nws yog cov nyiaj them yug lub cev ntawm hluav taws xob Cheebtsam thiab yog cov cab kuj ntawm hluav taws xob kev twb kev txuas ntawm hauv components.Because nws yog los ntawm hluav taws xob printing, nws yog hu ua "sau" Circuit Court board.
2. PCBA = los ua ke ntawm PCB .Tus ntau yam siv hluav taws xob tau koom ua ke rau hauv Circuit Court board los ntawm tus nto ntim process.Next los rau ntawm lub box los ua ke, uas assembles lub dho PCB thiab lub plhaub rau ntawv rau hauv lub tiav lawm product.In lwm yam lus, cov liab qab PCB Board yog dhau los ntawm SMT thiab tag nrho cov txheej txheem ntawm cov DIP plug-nyob rau hauv, raug xa mus rau raws li PCBA.This yog ib tug kheev siv style ntawm kev sau ntawv nyob rau hauv lub teb chaws, thiab nyob rau hauv Teb chaws Europe thiab lub tebchaws United States yog PCB'A txheem sau ntawv yog ib tug ntxiv point. PCBA, nws yog ib qhov PCB uas tau raug soldered.
3.What yog qhov txawv ntawm PCB thiab PCBA?
PCB hais txog rau hauv Circuit Court board, thiab lub PCBA hais txog lub rooj sib txoos ntawm cov Circuit Court board plug-nyob rau hauv thiab lub SMT txheej txheem.
Ib tug yog tus tiav lawm phaj thiab lwm yam yog ib tug liab qab phaj
PCB (Luam Circuit Court Board) yog hu ua " Luam Circuit Court Board". Nws yog ua los ntawm epoxy iav cob khoom, uas yog muab faib ua 4, 6 thiab 8 khaubncaws sab nraud povtseg raws li tus xov tooj ntawm lub teeb liab khaubncaws sab nraud povtseg, thiab yog feem ntau nyob rau hauv 4 los yog 6 laminates.The nti thiab lwm yam thaj ua rau thaj yog txuas mus rau lub PCB.
PCBA yuav tsum to taub raws li hauv lub tiav lawm Circuit Court board, uas yog, cov txheej txheem rau cov Circuit Court board tiav ua ntej laij PCBA.
PCBA = Luam Cirruit Board + los ua ke.
Nyob rau hauv lwm yam lus, cov liab qab PCB Board yog dhau los ntawm SMT thiab tag nrho cov txheej txheem ntawm cov DIP plug-nyob rau hauv, raug xa mus rau raws li PCBA
PCB Luam Circuit Court Board rau luv luv tsiaj, feem ntau yog nyob rau hauv insulating cov ntaub ntawv uas, raws li lub predetermined tsim, lub ntawv Circuit Court, ntawv ntsiab los yog ib tug ua ke ntawm ob tug ntawm cov conductive graphics hu ua lub Luam electronic.The conductive qauv ntawm cov hluav taws xob sib txuas ntawm cheebtsam rau insulating substrate yog hu ua cov ntawv luam circuit.In no txoj kev, cov ntawv luam siv hluav taws xob los yog luam circuit Court yog hu ua p rinted circuit Court board , kuj hu ua luam board los yog luam circuit Court board.
5.OEM / ODM / EMS cov kev pab cuam rau cov ntawv luam Circuit Court board los ua ke :
