Muaj ntau txoj kev xaiv khoom siv tau los kho 12-txheej PCB boards. Cov no suav nrog ntau yam khoom siv hluav taws xob, cov nplaum, cov ntaub ntawv txheej, thiab lwm yam. Thaum qhia txog cov khoom siv tshwj xeeb rau 12-txheej PCBs, koj tuaj yeem pom tias koj cov chaw tsim khoom siv ntau cov ntsiab lus. Koj yuav tsum muaj peev xwm nkag siab cov ntsiab lus uas siv los ua kom yooj yim sib txuas lus ntawm koj thiab cov chaw tsim khoom.
Kab lus no muab cov lus piav qhia luv luv ntawm cov lus uas feem ntau siv los ntawm PCB cov tuam txhab.
Thaum qhia txog cov khoom xav tau rau 12-txheej PCB, koj yuav pom tias nws nyuaj rau nkag siab cov ntsiab lus hauv qab no.
Cov khoom siv hauv paus - yog cov khoom siv insulating uas tsim cov qauv xav tau. Nws tuaj yeem nruj lossis hloov tau; qhov kev xaiv yuav tsum nyob ntawm qhov xwm txheej ntawm daim ntawv thov, txheej txheem tsim khoom thiab thaj chaw thov.
Npog txheej - Qhov no yog cov khoom siv insulating siv rau ntawm tus qauv conductive. Kev ua haujlwm zoo rwb thaiv tsev tuaj yeem tiv thaiv Circuit Court nyob rau hauv ib puag ncig huab cua thaum muab cov hluav taws xob rwb thaiv tsev zoo.
Reinforced adhesive-cov khoom siv ntawm cov nplaum tuaj yeem txhim kho los ntawm kev ntxiv iav fiber ntau. Adhesives nrog iav fiber ntxiv yog hu ua reinforced adhesives.
Adhesive-dawb cov ntaub ntawv- Feem ntau, cov ntaub ntawv tsis muaj nplaum yog tsim los ntawm ntws thermal polyimide (feem ntau siv polyimide yog Kapton) ntawm ob txheej ntawm tooj liab. Polyimide yog siv los ua cov nplaum, tshem tawm qhov xav tau siv cov nplaum xws li epoxy lossis acrylic.
Liquid photoimageable solder resist-Piv nrog cov zaj duab xis qhuav solder resist, LPSM yog ib txoj kev raug thiab ntau yam. Cov txheej txheem no tau raug xaiv los siv daim npog ntsej muag nyias nyias. Ntawm no, kev yees duab yees siv tshuab yog siv los tshuaj tsuag solder tiv thaiv ntawm lub rooj tsavxwm.
Curing-Qhov no yog cov txheej txheem ntawm kev siv cov cua sov thiab lub siab ntawm lub laminate. Qhov no yog ua los tsim cov yuam sij.
Cladding los yog cladding - ib txheej nyias los yog daim ntawv ntawm cov ntawv ci tooj liab txuas rau cladding. Cov khoom no tuaj yeem siv los ua cov khoom siv yooj yim rau PCB.
Cov lus qhia saum toj no yuav pab koj thaum qhia txog cov kev xav tau rau 12-txheej PCB nruj. Txawm li cas los xij, cov no tsis yog ib daim ntawv teev tag nrho. PCB cov tuam txhab siv ob peb lwm nqe lus thaum sib txuas lus nrog cov neeg siv khoom. Yog tias koj muaj teeb meem nkag siab txog cov ntsiab lus thaum lub sijhawm sib tham, thov hu rau lub chaw tsim khoom.
