Hauv kev lag luam hluav taws xob, precision yog qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov ntawv luam tawm hluav taws xob cov laug cam (PCBs). Granite yog lub pob zeb ntawm qhov no precision thiab ib qho ntawm cov ntaub ntawv nthuav dav tshaj plaws. Cov kev tshawb fawb qab granite lub luag haujlwm hauv PCB ntau lawm yog qhov ntxim nyiam sib xyaw ntawm geology, engineering, thiab thev naus laus zis.
Granite yog cov pob zeb ua ke ua ke ntawm quartz, feldspar, thiab mica uas muaj qhov tsis txaus ntseeg thiab muaj txiaj ntsig. Cov khoom siv no ua granite ib cov khoom zoo tshaj plaws rau kev tsim cov pcb ntau lawm nto. Lub flatness thiab rigidity ntawm granite slabs muab lub platform ruaj khov rau cov txheej txheem nyuaj, xws li cov photolithography thiab etching. Ib qho kev sib txawv nyob rau hauv cov tiaj tiaj tiaj nrees tuaj yeem ua rau cov kev ua yuam kev tseem ceeb hauv cov txheej txheem sib xyaw, ua haujlwm ntawm cov haujlwm ntawm cov khoom kawg.
Tsis tas li ntawd, granite's thermal stability yog lwm qhov tseem ceeb. Thaum lub sijhawm pcb tsim kev tsim qauv, cua sov yog koom nrog ntawm ntau theem. Granite tuaj yeem tiv thaiv ntau qhov kub tsis muaj dabtsi yog khoov lossis deforming, kom ntseeg tau tias qhov tseeb ntawm PCB teeb tsa yog tswj tau thoob plaws hauv lub voj voog ntau lawm. Qhov kev txhawb nqa thermal no yog qhov tseem ceeb rau cov txheej txheem xws li soldering, uas qhov twg kub hloov tuaj yeem ua rau tsis muaj cai thiab tuaj yeem ua rau tsis zoo thiab tsis xws luag.
Tsis tas li ntawd, cov kev tsis muaj-pranite txwv tsis pub muaj kev sib kis, uas yog qhov tseem ceeb hauv ib puag ncig hom dej huv uas tau tsim tawm. Hmoov av thiab cov lus tuaj yeem yooj yim cuam tshuam cov txheej txheem ua kom zoo sib xws nrog pcb tsim, thiab cov av granite pab txo cov kev pheej hmoo no.
Hauv cov ntsiab lus, lub hauv paus scientific rau granite qhov precision hauv PCB ntau lawm nta nyob rau hauv nws cov khoom tshwj xeeb lub cev. Granite lub ruaj khov, cua sov kuj, thiab huv ua rau nws muaj cov khoom siv hluav taws xob, kom muaj cov khoom lag luam uas ua tau zoo tshaj plaws thiab kev ntseeg tau. Raws li thev naus laus zis txuas ntxiv mus ua ntej, GRANITE yuav tsis ntseeg txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev nrhiav kev ua kom haum hauv cov khoom siv hluav taws xob.
