Muab piv cov chaw granite thiab cov hlau hauv PCB punching daim ntawv thov.

 

Hauv cov ntawv luam tawm Circuit Court (PCB) kev tsim khoom, precision thiab durability yog qhov tseem ceeb. Ib qho tseem ceeb ntawm cov txheej txheem yog qhov cim ntawm PCB, thiab cov khoom xaiv rau cov khoom siv tau tuaj yeem cuam tshuam ntau lawm thiab ua tau zoo. Ob yam khoom siv uas siv nyob rau hauv cov ntsiab lus teb yog granite thiab hlau, txhua tus nrog lawv tus kheej thiab qhov tsis zoo.

Granite Cheebtsam yog paub rau lawv qhov kev ruaj khov ruaj khov thiab rigidity. Lub ntom ntom ntawm ntuj pob zeb muab lub hauv paus ruaj khov uas txo cov kev co thaum lub zog stamping, yog li nce qhov tseeb thiab txo cov khoom hnav ntawm cov cuab yeej stamping. Qhov kev ruaj khov no tau txais txiaj ntsig zoo tshaj plaws nyob rau hauv cov ntawv thov siab ceev, qhov twg txawm tias kev txav me me tuaj yeem ua rau muaj kev tsis zoo thiab tsis meej. Ib qho ntxiv, cov granite yog resistant rau thermal expansion, kom ua tau zoo sib xws ntawm kev sib txawv, uas yog qhov tseem ceeb nyob rau hauv ib puag ncig uas kub tiam yog kev txhawj xeeb.

Cov khoom siv hlau, Cheebtsam hlau, yog nyiam rau lawv lub zog thiab lub zog. Steel seem tsis tshua muaj qhov yuav nti tshaj li granite, ua rau lawv xaiv tau kev ntseeg siab rau siab ntau lawm. Ib qho ntxiv, cov khoom siv hlau tuaj yeem yooj yim machined tau yooj yim kom tau raws li qhov yuav tsum tau ua, muab tsim qauv tsim nyog tias granite tsis tuaj yeem sib phim. Txawm li cas los xij, cov khoom siv hlau yog nquag ua xeb thiab xeb, uas tuaj yeem yog qhov tsis zoo uas muaj kev cuam tshuam loj hauv noo lossis muaj tshuaj xeb ib puag ncig.

Thaum sib piv cov kev ua tau zoo ntawm granite thiab steel rau PCB stamping daim ntaub ntawv, qhov kev txiav txim siab kawg yog nyob ntawm cov kev xav tau tshwj xeeb ntawm kev tsim khoom. Txog kev ua haujlwm uas precision thiab ruaj khov yog qhov tseem ceeb, granite yuav yog qhov kev xaiv zoo tshaj plaws. Hloov siab, rau cov kev ua haujlwm uas xav tau durability thiab kev yoog tau, cov hlau yuav muaj txiaj ntsig zoo dua. Nkag siab txog cov khoom tshwj xeeb ntawm txhua cov khoom yog qhov tseem ceeb rau cov tuam ntxhab tsom rau kev ua kom zoo rau lawv cov txheej txheem pcb ntau lawm.
