PCB hais txog lub rooj tsav xwm hauv Circuit Court, thiab PCBA yog hais txog qhov kev sib txuas lus hauv Circuit Board nrog lub rooj sib tham, SMT Kev Tshawb Fawb.
Ib tug yog ib lub phaj tiav, ib qho yog ib qho khoom plig liab qab. PCB (luam tawm Circuit Board) yog hu ua "printed Circuit Board", los ntawm epoxy iav ntaub material, Raws li qhov sib txawv ntawm nws cov txheej txheem sib npaug yog muab faib ua 4, 6, 8 txheej phaj, 4, 6 txheej yog feem ntau.
Chip thiab lwm yam khoom SMD raug muab tso rau PCB.
PCBA kuj yuav to taub hais tias yog lub rooj tsav xwm tiav lawm, tab sis kuj yog nyob rau ntawm pawg thawj coj saib xyuas ntawm kev ua tiav ntawm qhov txheej txheem tom qab PCBA tuaj yeem suav.
PCBA = luam tawm cirruit Board + Assembly.
Ntawd yog, PCB khoob lug ntawm lub smt, thiab tom qab ntawd los ntawm txoj hlua ntsaws tag nrho cov txheej txheem, xa mus rau PCBA. PCB (luam tawm Circuie Board) luam tawm ntawm lub rooj tsav xwm sau ua haujlwm, feem ntau ntawm cov khoom siv insulating, raws li tus qauv tsim, ua ntawm cov ntawv xov tooj, cov ntawv luam tawm lossis ob qho lus ua ke ntawm lub npe hu ua Circuit Court. Thiab nyob rau hauv cov thev dej sab hauv kom muab hluav taws xob sib txuas ntawm cov qauv ntawm cov qauv siv hluav taws xob, hu ua kab hluav taws xob.
Nyob rau hauv txoj kev no, lub xov xwm luam tawm lossis daim xov hluav taws xob ntawm daim ntawv cog lus tiav yog hu ua pawg thawj coj saib xyuas, uas yog hu ua Circuit Court Circuits lossis Circuits luam tawm. Tus txheem PCB tsis muaj cov khoom thiab feem ntau hu ua "cov ntawv luam tawm Circuit Board board Print Cable (PWB)".
