Cov khoom granite hauv PCB drilling thiab milling tshuab muaj kev tiv thaiv hluav taws xob zoo li cas, thiab nws puas pab txo qhov cuam tshuam hluav taws xob?

Cov tshuab drilling thiab milling PCB siv dav hauv kev lag luam tsim khoom siv hluav taws xob. Lawv tau tsim los tho thiab milling cov laug cam luam tawm (PCBs) nrog qhov tseeb thiab ceev. Txawm li cas los xij, cov tshuab no tuaj yeem tsim kev cuam tshuam hluav taws xob (EMI) thaum lawv ua haujlwm, uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hluav taws xob nyob ze. Txhawm rau kom txo qhov teeb meem no, ntau lub tuam txhab tsim khoom siv cov khoom granite hauv lawv cov tshuab drilling thiab milling PCB.

Granite yog ib yam khoom uas muaj nyob hauv ntuj, muaj zog heev uas muaj cov yam ntxwv zoo heev rau kev tiv thaiv hluav taws xob. Nws feem ntau siv rau hauv kev tsim cov tshuab hais lus zoo thiab cov tshuab MRI. Cov yam ntxwv ntawm granite ua rau nws yog ib qho zoo tagnrho rau kev siv hauv kev tsim cov tshuab drilling thiab milling PCB. Thaum muab tso rau hauv cov tshuab no, cov khoom granite tuaj yeem txo qis EMI thiab nws cov teebmeem rau cov khoom siv hluav taws xob nyob ze.

EMI tshwm sim thaum cov teb hluav taws xob electromagnetic raug tsim los ntawm cov khoom siv hluav taws xob. Cov teb no tuaj yeem ua rau muaj kev cuam tshuam nrog lwm cov khoom siv hluav taws xob, ua rau muaj kev ua haujlwm tsis zoo lossis ua tsis tiav. Nrog rau qhov nyuaj ntawm cov txheej txheem hluav taws xob, qhov xav tau kev tiv thaiv EMI zoo tau dhau los ua qhov tseem ceeb dua. Kev siv cov khoom granite hauv PCB drilling thiab milling tshuab tuaj yeem muab qhov kev tiv thaiv no.

Granite yog ib qho khoom rwb thaiv tsev zoo heev thiab tsis coj hluav taws xob. Thaum EMI raug tsim tawm hauv lub tshuab drilling thiab milling PCB, nws tuaj yeem nqus tau los ntawm cov khoom granite. Lub zog nqus tau ces raug tshem tawm hauv daim ntawv ntawm cua sov, txo cov theem EMI tag nrho. Qhov no yog qhov tseem ceeb hauv cov txheej txheem tsim khoom ntawm PCBs vim tias cov theem siab ntawm EMI tuaj yeem ua rau cov laug cam tsis zoo. Kev siv cov khoom granite hauv PCB drilling thiab milling tshuab tuaj yeem txo qhov kev pheej hmoo ntawm cov laug cam tsis zoo vim EMI.

Ntxiv mus, granite yog qhov ruaj khov heev thiab tiv taus kev hnav thiab tsim kua muag. Nws muaj cov coefficient qis ntawm thermal expansion, uas txhais tau tias nws tuaj yeem tiv taus qhov kub thiab txias heev yam tsis muaj warping lossis tawg. Cov yam ntxwv no ua rau cov khoom granite zoo tagnrho rau kev siv hauv qhov chaw ua haujlwm hnyav ntawm PCB drilling thiab milling tshuab. Lub zog ntawm cov khoom granite ua kom ntseeg tau tias lub tshuab yuav ua haujlwm tau zoo rau ntau xyoo, txo cov nqi kho thiab lub sijhawm tsis ua haujlwm.

Xaus lus, kev siv cov khoom granite hauv PCB drilling thiab milling tshuab yog ib txoj hauv kev zoo los txo cov EMI thiab kev pheej hmoo ntawm cov laug cam tsis zoo. Cov khoom tiv thaiv ntawm granite ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv hauv kev tsim cov tshuab no. Qhov ruaj khov thiab kev tiv thaiv kev hnav thiab tsim kua muag ua rau cov khoom granite yog qhov kev xaiv zoo tshaj plaws rau qhov chaw ua haujlwm hnyav ntawm PCB drilling thiab milling tshuab. Cov chaw tsim khoom uas suav nrog cov khoom granite hauv lawv cov tshuab tuaj yeem ua kom lawv cov neeg siv khoom tau txais cov tshuab ruaj khov thiab txhim khu kev qha uas ua haujlwm tau zoo.
