PCB tuaj yeem muab cais ua ib lub vaj huam sib luag, ob chav vaj huam sib luag, txheej txheej txheej ntau txheej, hloov pauv tau PCB pawg thawj coj saib (pawg tswj hwm tau yooj yim), PCB pawg tswj hwm nruj, ua tau yooj yim-hloov pauv PCB board (txhav-hloov tau lub rooj tsavxwm), thiab ntxiv rau. Luam Circuit Board (PCB), tseem hu ua Printed Circuit Board, yog cov khoom siv hluav taws xob tseem ceeb, yog kev txhawb nqa ntawm cov khoom siv hluav taws xob, yog tus xa khoom ntawm cov khoom siv hluav taws xob txuas hluav taws xob, vim nws tau tsim los ntawm kev siv tshuab luam ntawv, yog li nws tseem hu ua “Luam tawm” Circuit Board. PCB yog ib daim phaj nyias uas muaj cov khoom siv sib txuas thiab lwm yam khoom siv hluav taws xob.

Ib, raws li kev faib tawm txheej txheej: faib ua ib lub vaj huam sib luag, ob chav vaj huam sib luag, thiab ntau txheej txheej. Cov rooj sib tham ntau txheej yog feem ntau yog 3-6 txheej, thiab cov rooj sib txig sib luag sib luag tuaj yeem ncav ntau dua 10 txheej.

(1) ib lub vaj huam sib luag

Ntawm daim phiaj xwm txheej luam tawm yooj yim, cov ntu tau mloog zoo rau ntawm ib sab thiab cov xov hlau tau tsom mus rau lwm qhov. Vim tias cov xov hlau zoo nkaus li tsuas yog ib sab, daim ntawv luam tawm Circuit board tau hu ua ib lub vaj huam sib luag. Kev siv hluav taws xob thaum ntxov siv hom kev sib tham ntawm lub rooj tsav xwm no vim tias muaj ntau txoj kev txwv nruj rau kev tsim qauv Circuit Court ntawm ib lub vaj huam sib luag (vim tias tsuas muaj ib sab xwb, cov hlua thaiv tsis tuaj yeem hla thiab yuav tsum tau khiav hauv txoj kev sib cais).

(2) ob chav vaj huam sib luag

Lub rooj tsav xwm hluav taws xob muaj cov xov hlau ntawm ob sab. Txhawm rau kom cov xov hlau ntawm ob sab sib txuas lus, yuav tsum muaj kev sib txuas zoo ntawm ob sab, uas yog hu ua phau ntawv qhia. Phau ntawv qhia qhov yog qhov me me hauv cov ntawv luam tawm Circuit Board, tau sau lossis coated nrog hlau, uas tuaj yeem txuas nrog cov xov hlau ntawm ob sab. Ob chav vaj huam sib luag tuaj yeem siv rau ntawm cov kab hluav taws xob sib txawv ntau dua li ib lub vaj huam sib luag vim tias thaj chaw loj dua ob zaug thiab cov hlua tuaj yeem sib cuam tshuam (nws tuaj yeem raug mob rau sab nraud).
