Dab tsi yog tus qauv xaiv cov khoom siv thiab cov khoom siv thaum sib dhos PCB?

PCB sib dhos ua tiav suav nrog kev tsim qauv tsim, PCB prototyping,SMT PCB pawg thawj coj saib, Cheebtsam khoom thiab lwm yam txheej txheem.Yog li, dab tsi yog PCBA pawg thawj coj ua cov khoom thiab cov txheej txheem xaiv substrate?

1. Kev xaiv cov khoom siv

Kev xaiv ntawm cov khoom yuav tsum tau ua tiav tag nrho ntawm thaj chaw tiag tiag ntawm SMB, thiab cov khoom sib xyaw yuav tsum raug xaiv kom deb li deb tau.Cov khoom me me yuav tsum tsis txhob ua qhov muag tsis pom kev kom tsis txhob nce tus nqi.IC pab kiag li lawm yuav tsum nco ntsoov tias tus pin puab thiab tus pin sib nrug;QFP nrog tsawg dua 0.5mm tus pin sib nrug yuav tsum tau ua tib zoo xav, koj tuaj yeem siv pob BGA ncaj qha.

Tsis tas li ntawd, daim ntawv ntim khoom ntawm cov khoom siv, kev sib txuas ntawm PCB, kev ntseeg siab ntawm SMT PCB los ua ke, thiab qhov ntsuas kub ntawm cov kabmob yuav tsum raug coj mus rau hauv tus account.Tom qab xaiv cov khoom, cov ntaub ntawv ntawm cov khoom yuav tsum raug tsim, suav nrog kev teeb tsa loj, tus pin loj thiab SMT chaw tsim khoom thiab lwm yam ntaub ntawv cuam tshuam.

2.Kev xaiv cov khoom siv hauv paus rau PCB

Cov khoom siv hauv paus yuav tsum raug xaiv raws li cov kev pabcuam ntawm SMB thiab cov kev xav tau ntawm kev siv tshuab thiab hluav taws xob.Tus naj npawb ntawm tooj liab clad ntawv ci nto (ib zaug, ob npaug los yog ntau txheej) ntawm substrate yog txiav txim siab raws li SMB qauv;Lub thickness ntawm lub substrate yog txiav txim raws li qhov loj ntawm SMB thiab qhov zoo ntawm cov khoom nyob rau hauv ib cheeb tsam.Thaum koj xaiv SMB substrates, yam xws li hluav taws xob kev ua tau zoo, Tg tus nqi (iav hloov kub), CTE, flatness thiab nqi thiab lwm yam ... yuav tsum xav txog.

Cov saum toj no yog cov ntsiab lus luv luv ntawmprinted Circuit Board los ua keua cov khoom thiab cov txheej txheem xaiv substrate.Yog xav paub ntxiv, koj tuaj yeem mus ncaj qha rau peb lub vev xaib: www.pcbfuture.com kom paub ntau ntxiv!
