PCBA yog dab tsi thiab qhov sib txawv ntawm PCB thiab PCBA yog dab tsi?
PCB yog dab tsi?
PCB=luam tawm Circuit board; Suav lub npe yog luam tawm Circuit board, tseem hu ua luam tawm Circuit board. Nws yog cov khoom siv hluav taws xob tseem ceeb, txhawb nqa cov khoom siv hluav taws xob, thiab cov nqa khoom siv hluav taws xob txuas hluav taws xob ntawm cov khoom siv hluav taws xob. Vim tias nws yog tsim los ntawm kev luam ntawv hluav taws xob, nws hu ua" luam tawm" Circuit Board.
PCBA yog dab tsi?
PCBA=sib dhos ntawm PCB. Ntau yam khoom siv hluav taws xob tau sib sau ua ke ntawm lub rooj tsav xwm hauv Circuit Court los ntawm txheej txheem ntim khoom. Tom ntej no yog lub thawv sib dhos, uas yog hais txog kev sib sau ua ke PCB nrog lub tsev kom tsim cov khoom tiav. Qhov ntawd yog hais, pawg thawj coj saib PCB dawb mus los ntawm SMT thauj khoom, thiab tom qab ntawd dhau los ntawm tag nrho cov txheej txheem tsim khoom ntawm DIP plug-in, hu ua PCBA. Nov yog ib txoj hauv kev yooj yim ntawm kev sau ntawv hauv Suav teb, thaum tus txheej txheem txheej txheem sau ntawv hauv Tebchaws Europe thiab Amelikas yog PCB' A, nrog oblique dot ntxiv. PCBA yog PCB nrog thaj rau ntawm nws.
Dab tsi yog qhov sib txawv ntawm PCB thiab PCBA?
PCB hais txog lub rooj tsav xwm hauv Circuit Court, thiab PCBA hais txog kev sib dhos ntawm lub rooj sib tham hauv Circuit Court, txheej txheem SMT.
Ib qho yog lub rooj tsavxwm tiav thiab lwm qhov yog lub rooj tsavxwm liab qab
PCB (Luam Circuit Board) hu ua" luam tawm Circuit board" thiab yog ua los ntawm cov khoom siv iav epoxy iav. Raws li tus naj npawb ntawm cov teeb liab txheej, nws tau muab faib ua 4, 6, thiab 8 txheej. 4 thiab 6 txheej yog qhov feem ntau. Cheebtsam SMD xws li cov chips tau muab tso rau ntawm PCB.
PCBA tuaj yeem nkag siab tias yog lub rooj tsav xwm ua tiav, uas txhais tau tias PCBA tuaj yeem suav tau tsuas yog tom qab cov txheej txheem ntawm lub rooj tsav xwm hauv Circuit tiav.
PCBA=Luam tawm Cirru Board + Los Ua Ke.
Qhov ntawd yog hais, lub PCB pawg thawj coj tsis dhau mus los ntawm SMT kev thauj khoom, thiab tom qab ntawd dhau los ntawm tag nrho cov txheej txheem tsim khoom ntawm DIP plug-in, hu ua PCBA.
PCB (Luam Circuit Board) yog lub npe luv ntawm cov ntawv luam tawm Circuit Board. Feem ntau, cov qauv coj ua los ntawm cov ntawv luam tawm, cov khoom luam tawm, lossis ua ke ntawm ob qho tib si ntawm cov khoom siv rwb thaiv tsev, raws li kev tsim ua ntej, tau hu ua luam tawm Circuit. Cov qauv coj ua uas muab hluav taws xob sib txuas ntawm cov khoom siv ntawm cov insulating substrate hu ua daim ntawv luam tawm. Ua li no, daim ntawv luam tawm Circuit lossis daim ntawv tiav ntawm daim ntawv luam tawm Circuit Circuit hu ua daim ntawv luam tawm Circuit board, tseem hu ua daim duab luam tawm Circuit board lossis luam ntawv Circuit Board.
Tsis muaj ib feem ntawm tus txheej txheem PCB, thiab nws feem ntau hu ua" Printed Wiring Board (PWB)" ;.
