Hauv kev lag luam hluav taws xob, qhov kev ua kom raug yog qhov tseem ceeb heev, tshwj xeeb tshaj yog hauv kev tsim cov ntawv luam tawm Circuit Board (PCBs). Granite yog lub hauv paus ntawm qhov kev ua kom raug no thiab yog ib qho ntawm cov ntaub ntawv nthuav tshaj plaws. Kev tshawb fawb tom qab granite lub luag haujlwm hauv kev tsim PCB yog kev sib xyaw ua ke ntawm geology, engineering, thiab technology.
Granite yog ib lub pob zeb ntuj tsim los ntawm quartz, feldspar, thiab mica uas muaj kev ruaj khov thiab ua tau ntev. Cov yam ntxwv no ua rau granite yog cov khoom siv zoo tshaj plaws rau kev tsim cov chaw tsim khoom PCB. Qhov tiaj tiaj thiab kev tawv ntawm cov granite slabs muab lub platform ruaj khov rau cov txheej txheem nyuaj uas koom nrog hauv kev tsim khoom PCB, xws li photolithography thiab etching. Txhua qhov kev hloov pauv ntawm qhov tiaj tiaj ntawm qhov chaw tuaj yeem ua rau muaj qhov yuam kev loj hauv kev sib dhos ntawm cov khoom, ua rau kev ua haujlwm ntawm cov khoom kawg tsis zoo.
Tsis tas li ntawd xwb, qhov ruaj khov ntawm granite thermal yog lwm yam tseem ceeb. Thaum lub sijhawm tsim PCB, kev cua sov muaj nyob rau ntau theem. Granite tuaj yeem tiv taus qhov kub siab yam tsis khoov lossis deforming, ua kom ntseeg tau tias qhov tseeb ntawm PCB layout raug tswj hwm thoob plaws hauv lub voj voog ntau lawm. Qhov kev ua kom sov thermal no yog qhov tseem ceeb rau cov txheej txheem xws li soldering, qhov twg qhov kub thiab txias hloov pauv tuaj yeem ua rau tsis sib xws thiab tsis zoo.
Tsis tas li ntawd xwb, granite tsis muaj qhov porous tiv thaiv kev ua qias tuaj, uas yog qhov tseem ceeb hauv chav huv uas PCBs raug tsim. Cov hmoov av thiab cov khoom me me tuaj yeem cuam tshuam cov txheej txheem yooj yim uas cuam tshuam nrog kev tsim PCB, thiab qhov chaw granite pab txo qhov kev pheej hmoo no.
Hauv kev xaus lus, lub hauv paus kev tshawb fawb rau granite qhov kev ua tau zoo hauv PCB yog nyob rau hauv nws cov khoom tshwj xeeb. Granite qhov kev ruaj khov, kev tiv taus cua sov, thiab kev huv si ua rau nws yog cov khoom siv tseem ceeb rau kev lag luam hluav taws xob, ua kom ntseeg tau tias PCBs tsim tawm yog qhov zoo tshaj plaws thiab kev ntseeg siab. Raws li thev naus laus zis txuas ntxiv mus, granite yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev nrhiav kev ua tau zoo hauv kev tsim khoom hluav taws xob.
