Muaj ntau ntau hom PCB Circuit Board nyob rau hauv kev ua lag luam, thiab nws yog ib qho nyuaj rau kev paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo. Hauv qhov no, ntawm no yog ob peb txoj hauv kev los txheeb xyuas qhov zoo ntawm PCB Circuit Boards.

Judging los ntawm tsos

1. Cov tsos ntawm weld seam

Txij li thaum muaj ntau yam ntawm PCB pawg thawj coj saib, yog tias qhov vuam tsis zoo, cov khoom siv hluav taws xob hauv Circuit Court yuav yooj yim poob, cuam tshuam rau cov vuam zoo thiab cov tsos ntawm lub rooj tsav xwm Circuit Court, yog li nws tseem ceeb heev kom muaj kev ruaj ntseg vuam.

2. Cov qauv kev cai rau qhov loj thiab tuab

Txij li cov PCB Circuit Boards muaj qhov sib txawv thicknesses piv rau cov qauv Circuit Court boards, cov neeg siv tuaj yeem ntsuas thiab xyuas raws li lawv tus kheej xav tau.

3. Lub teeb thiab xim

Feem ntau, sab nraud PCB Circuit Board yog them nrog tus number case rau rwb thaiv tsev. Yog tias cov xim ntawm lub rooj tsavxwm tsis ci thiab tsis muaj number case tsawg, nws txhais tau hais tias cov rwb thaiv tsev nws tus kheej tsis zoo.

Kev txiav txim los ntawm cov khoom siv phaj

1. Ordinary HB cardboard yog pheej yig thiab yooj yim rau deform thiab tawg. Nws tsuas tuaj yeem ua rau hauv ib lub vaj huam sib luag xwb. Cov khoom siv saum npoo yog xim daj tsaus thiab muaj ntxhiab tsw ntxhiab. Cov txheej tooj liab yog ntxhib thiab nyias.

2. Ib leeg-sided 94V0 thiab CEM-1 boards kuj kim dua li cov duab los qhia. Cov xim ntawm cov khoom nto yog lub teeb daj. Lawv tsuas yog siv rau kev lag luam boards thiab lub hwj chim boards nrog kev tiv thaiv hluav taws.

3. Fiberglass board muaj tus nqi siab dua, lub zog zoo, thiab yog ntsuab ntawm ob sab. Feem ntau, PCB Circuit Boards feem ntau yog ua los ntawm cov khoom siv no. Cov txheej tooj liab tuaj yeem ua tau zoo heev thiab zoo, tab sis chav tsev board kuj hnyav heev. Tsis muaj teeb meem dab tsi xim ntawm tus number case yog luam tawm ntawm lub rooj tsav xwm PCB, nws yuav tsum du thiab tiaj tus, thiab yuav tsum tsis txhob muaj cov kab cuav, raug tooj liab lossis npuas.
