Dab tsi Yog Cov Qauv Txheej Txheem Zoo Rau Cov Rooj Sib Tw PCB
Jul 16, 2020
PCB lub rooj tsavxwm soj ntsuam zoo feem ntau suav nrog kev tshuaj xyuas kom pom, kev soj ntsuam txuas txuas thiab tshuaj xyuas weldability.I. PCB lub rooj tsav xwm pawg thawj coj saib cov qauv soj ntsuam
1. Seb puas saum npoo ntawm PCB pawg thawj coj ua tau zoo thiab qib, txawm tias yuav muaj cov kab tsoo lossis txhuam.Tsis muaj qhov to mus los ntawm lub qhov, qhov tsis ncaj ncees lawm los yog tooj liab ntawv ci ib puag ncig qhov tshwm sim ntawm kev tab.
2. Kev sib xyaw ntawm cov hlau daim duab, npog lub rooj tsav xwm PCB Circuit nrog cov duab thaij, thiab txiav txim siab seb qhov dav thiab cov qauv ntawm xaim ua tau raws li qhov xav tau.Tsis muaj sab hauv los yog tawg kab ntawm kab ntawv luam tawm, tsis muaj jagged thais ntawm ntug kab, tsis muaj xov luv luv uas yuav tsum tsis txhob txuas.
3. Seb sab nraud qhov loj ntawm PCB pawg thawj coj saib hauv tsev ua tau raws li qhov yuav tsum tau ua.
Ii. PCB pawg thawj coj saib khoom sib txuas soj ntsuam cov qauv
Multilayer PCB pawg thawj coj xav tau kev ntsuam xyuas rau kev sib txuas.Qhov multimeter feem ntau yog siv los xyuas seb lub PCB Circuit Board txuas nrog.
Iii. PCB Circuit Board board weldability soj ntsuam txheem
Xyuas lub peev xwm wetting ntawm solder rau PCB board cov duab thaum soldering Cheebtsam rau PCB board.
