Tam sim no, hauv kev lag luam khoom lag luam hluav taws xob, PCB pawg thawj coj saib yog qhov tsis tseem ceeb raws li ib qho ntawm cov khoom siv hluav taws xob tseem ceeb. Tam sim no, PCB pawg thawj coj muaj ntau hom, xws li PCB ntau zaus, microwave cua sov PCB board thiab lwm hom luam tawm PCB board tau dhau los ua lub koob npe nrov hauv kev muag khoom. Cov tuam txhab tsim khoom PCB muaj cov txheej txheem tshwj xeeb rau ntau hom PCB pawg thawj coj saib. Tab sis feem ntau, PCB kev tsim khoom thiab kev ua haujlwm yuav tsum raug txiav txim siab ob lossis peb qib.

1. Xav txog kev xaiv phaj

Qhov tseem ceeb ntawm PCB pawg thawj coj tuaj yeem faib ua cov khoom siv tshuaj lom neeg thiab cov khoom tsis muaj tshuaj lom ob hom, txhua cov khoom siv feem ntau muaj nws qhov tshwj xeeb. Yog li ntawd, hom phaj tseeb yuav tsum suav nrog lub zog dielectric, hom tooj liab ntawv ci, tuab ntawm lub hauv paus zawj, thiab cov yam ntxwv ntawm kev tsim khoom thiab ua tiav. Ntawm lawv, qhov tuab ntawm cov ntawv ci tooj liab saum npoo yog qhov xwm txheej tseem ceeb ua rau cov yam ntxwv ntawm luam tawm PCB pawg thawj coj saib. Feem ntau, cov tuab tuab, rau cov txheej txheem yooj yim etching thiab txhim kho cov qauv ntawm qhov tseeb muaj qhov zoo.

2. Coj mus rau hauv tus account qhov teeb tsa ntawm cov txheej txheem tsim khoom

Ib puag ncig ib puag ncig ntawm PCB pawg thawj coj saib xyuas kev tsim khoom thiab ua haujlwm yog qib tseem ceeb heev, thiab kev tswj hwm kev ua haujlwm kub thiab txheeb ze ntawm huab cua yog qhov tseem ceeb tshwj xeeb. Yog tias qhov ntsuas kub hloov pauv ua haujlwm pom tseeb dhau, nws yuav ua rau lub qhov tig ntawm lub phaj tawg. Yog tias cov huab cua nyob ib puag ncig huab cua loj heev, kev tsim hluav taws xob nuclear muaj kev phom sij tsis zoo rau cov yam ntxwv ntawm phaj nrog lub peev xwm muaj zog bibitive, feem ntau qhia hauv qib dielectric kev ua tau zoo. Yog li, nws yog qhov tsim nyog los tswj cov txheej txheem ib puag ncig ib puag ncig zoo hauv PCB pawg thawj coj saib kev tsim khoom thiab tsim khoom.

3. Xav txog kev xaiv cov txheej txheem tsim khoom

Kev tsim PCB yog yooj yim heev kom ua tau raws li kev tsim txom ntawm ntau yam ntsiab lus, kev tsim khoom thiab txheej txheem txheej txheej, qhov ua haujlwm thev naus laus zis, txheej txheej txheej thiab lwm cov txheej txheem tsim khoom yuav ua rau raug mob PCB pawg thawj coj saib zoo. Yog li ntawd, txiav txim siab ib puag ncig ib puag ncig ntawm cov txheej txheem tsim khoom no, PCB kev tsim khoom thiab ua haujlwm tau ua ke nrog cov yam ntxwv ntawm kev tsim cov tshuab thiab khoom siv, nws tuaj yeem hloov kho tau yooj yim raws li hom PCB pawg thawj coj thiab xav tau ntawm kev tsim khoom thiab ua tiav.

Los ntawm sab laug thiab sab xis, xaiv PCB pawg thawj coj, teeb tsa cov txheej txheem tsim khoom thiab xaiv cov txheej txheem tsim khoom yuav tsum raug coj mus rau hauv tus account hauv kev tsim khoom thiab ua tiav ntawm PCB pawg thawj coj saib. Ib qho ntxiv, cov ntaub ntawv tsim kho ntawm PCB pawg thawj coj thiab txoj hauv kev qhib yog qib uas yuav tsum tau ua tib zoo xaiv, uas muaj feem cuam tshuam nrog qhov ci ntawm lub phaj ntawm cov khoom tiav ntawm lub hwj chim Circuit Court ntim tshuab luam ntawv.
