PCB txhais ua lus Suav hu ua luam tawm Circuit board, vim tias nws yog tsim los ntawm kev luam ntawv hluav taws xob, thiaj li hu ua “luam tawm” Circuit Board. PCB yog cov khoom siv hluav taws xob tseem ceeb hauv kev lag luam hluav taws xob, yog lub cev txhawb nqa ntawm cov khoom siv hluav taws xob, yog cov khoom siv txuas hluav taws xob ntawm cov khoom siv hluav taws xob. PCB tau siv dav hauv kev tsim khoom thiab tsim khoom ntawm cov khoom siv hluav taws xob, yog vim li cas nws thiaj tuaj yeem siv tau dav.

Cov yam ntxwv tshwj xeeb ntawm PCB tau sau ua ke raws li hauv qab no:

1, thaiv qhov ceev yog siab, qhov me me, qhov hnyav, ua kom yooj yim rau cov khoom siv hluav taws xob me me.

2, vim tias cov duab muaj qhov rov ua tau zoo dua qub thiab zoo ib yam, txo cov thaiv thiab ua kom yuam kev, txuag cov cuab yeej tu, debug thiab lub sijhawm tshuaj xyuas.

3, muaj txiaj ntsig zoo rau kev siv tshuab, kev tsim khoom tsis siv neeg, txhim kho kev tsim khoom thiab txo tus nqi ntawm cov khoom siv hluav taws xob.

4, kev tsim qauv tuaj yeem ua tus qauv, muaj txiaj ntsig zoo rau kev sib pauv.

Luam Circuit Board (PCBA) yog Luam Circuit Board (PCB), Luam Circuit Board (SMT), thiab DIP plug-in (DIP). Nco tseg: SMT thiab DIP yog ob txoj hauv kev sib koom ua ke ntawm PCB. Qhov sib txawv tseem ceeb yog tias SMT tsis xav tau qhov tho qhov hauv PCB. Hauv DIP, tus lej PIN tus lej ntawm ntu tau muab tso rau hauv lub qhov uas twb tau xyaum lawm.

SMT nto tshuab thev naus laus zis feem ntau siv tshuab SMT txhawm rau txhim kho qee qhov me me ntawm PCB pawg thawj coj. Nws cov txheej txheem tsim khoom suav nrog PCB pawg thawj coj saib xyuas qhov chaw, luam ntawv muab tshuaj txhuam txhuam, SMT tshuab mounting, rov qab vuam siv hluav taws xob thiab tshuaj xyuas ntau lawm. DIP, lossis “plug-in,” yog kev ntxig ib feem ntawm PCB pawg thawj coj, uas yog kev sib koom ua ke ntawm ib feem hauv daim ntawv ntsaws-ntsaws thaum qhov loj dua thiab tsis haum rau kev siv tshuab. Nws cov txheej txheem tsim khoom tseem ceeb yog: muab tshuaj txhuam cov pos hniav, ntsaws rau hauv, tshuaj xyuas, yoj yoj yaug, txhuam qhov txhuam thiab ua kev tshuaj xyuas.

Raws li tuaj yeem pom los ntawm cov lus taw qhia saum toj no, PCBA feem ntau hais txog kev ua haujlwm, uas tseem tuaj yeem nkag siab tias yog lub rooj tsav xwm ua tiav. PCBA tuaj yeem suav tsuas yog tom qab tag nrho cov txheej txheem ntawm PCB pawg thawj coj ua tiav. Ib lub PCB yog cov ntawv luam tawm Circuit Court uas tsis muaj qhov seem ntawm nws. Feem ntau, PCBA yog lub rooj tsavxwm tiav; PCB yog lub rooj tsav xwm liab qab.
