Hauv kev tsim cov ntawv luam tawm Circuit Board (PCB), qhov tseeb thiab kev ruaj khov yog qhov tseem ceeb heev. Ib qho tseem ceeb ntawm cov txheej txheem yog kev luam ntawv ntawm PCB, thiab kev xaiv cov khoom siv rau cov khoom luam ntawv tuaj yeem cuam tshuam rau qhov zoo thiab kev ua haujlwm ntawm kev tsim khoom. Ob yam khoom siv uas siv rau hauv cov ntsiab lus no yog granite thiab hlau, txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo.
Cov khoom siv granite paub txog lawv qhov kev ruaj khov thiab kev tawv. Qhov ntom ntawm cov pob zeb ntuj tsim ua rau lub hauv paus ruaj khov uas txo qhov kev co thaum lub sijhawm stamping, yog li ua kom raug thiab txo qhov hnav ntawm cov cuab yeej stamping. Qhov kev ruaj khov no tshwj xeeb tshaj yog pab tau rau cov ntawv thov ceev ceev, qhov twg txawm tias qhov kev txav me me tuaj yeem ua rau tsis sib xws thiab muaj qhov tsis zoo. Tsis tas li ntawd, granite tiv taus kev nthuav dav thermal, ua kom muaj kev ua tau zoo tas li ntawm qhov kub sib txawv, uas yog qhov tseem ceeb hauv cov chaw uas muaj kev txhawj xeeb txog kev tsim cua sov.
Cov khoom siv hlau, ntawm qhov tod tes, yog qhov nyiam dua rau lawv lub zog thiab kev ruaj khov. Cov khoom siv hlau tsis tshua muaj peev xwm tawg dua li granite, ua rau lawv yog qhov kev xaiv txhim khu kev qha rau kev tsim khoom ntau. Tsis tas li ntawd, cov khoom siv hlau tuaj yeem yooj yim tshuab thiab kho kom haum rau cov kev xav tau tshwj xeeb, muab kev ywj pheej tsim uas granite tsis tuaj yeem phim. Txawm li cas los xij, cov khoom siv hlau yooj yim xeb thiab xeb, uas tuaj yeem ua rau muaj kev tsis zoo hauv cov chaw noo noo lossis cov tshuaj lom neeg xeb.
Thaum piv rau qhov kev ua tau zoo ntawm granite thiab hlau rau PCB stamping daim ntawv thov, qhov kev txiav txim siab kawg nyob ntawm qhov xav tau tshwj xeeb ntawm cov txheej txheem tsim khoom. Rau cov haujlwm uas qhov tseeb thiab ruaj khov yog qhov tseem ceeb, granite yuav yog qhov kev xaiv zoo tshaj plaws. Ntawm qhov tod tes, rau cov haujlwm uas xav tau kev ruaj khov thiab kev hloov pauv tau, hlau yuav muaj txiaj ntsig zoo dua. Kev nkag siab txog cov khoom tshwj xeeb ntawm txhua yam khoom siv yog qhov tseem ceeb rau cov tuam txhab tsim khoom uas tsom mus rau kev ua kom zoo dua lawv cov txheej txheem tsim khoom PCB.
