Dab tsi yog electromagnetic shielding kev ua tau zoo ntawm granite Cheebtsam hauv PCB drilling thiab milling tshuab, thiab nws puas pab txo cov electromagnetic cuam tshuam?

PCB drilling thiab milling tshuab yog siv dav hauv kev lag luam hluav taws xob tsim khoom.Lawv yog tsim los rau laum thiab zeb luam ntawv Circuit Court boards (PCBs) nrog high precision thiab ceev.Txawm li cas los xij, cov tshuab no tuaj yeem tsim hluav taws xob cuam tshuam (EMI) thaum lawv ua haujlwm, uas tuaj yeem cuam tshuam kev ua haujlwm ntawm cov khoom siv hluav taws xob nyob ze.Txhawm rau txo qhov teeb meem no, ntau lub tuam txhab tau koom nrog cov khoom siv granite hauv lawv cov PCB drilling thiab milling tshuab.

Granite yog ib txwm tshwm sim, cov khoom siv high-density uas muaj cov khoom tiv thaiv electromagnetic zoo heev.Nws yog feem ntau siv rau hauv kev tsim kho ntawm high-end audiophile hais lus tshuab thiab MRI tshuab.Cov khoom ntawm granite ua rau nws yog ib tus neeg sib tw zoo tshaj plaws rau kev siv hauv kev tsim kho ntawm PCB drilling thiab milling tshuab.Thaum muab tso rau hauv cov tshuab no, cov khoom siv granite tuaj yeem txo EMI thiab nws cov teebmeem ntawm cov khoom siv hluav taws xob nyob ze.

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

Granite yog ib qho zoo heev insulator thiab tsis ua hluav taws xob.Thaum EMI tsim nyob rau hauv PCB drilling thiab milling tshuab, nws tuaj yeem nqus tau los ntawm cov khoom siv granite.Lub zog absorbed ces dissipated nyob rau hauv daim ntawv ntawm tshav kub, txo tag nrho cov EMI theem.Cov yam ntxwv no yog qhov tseem ceeb hauv kev tsim cov txheej txheem ntawm PCBs vim tias qib siab EMI tuaj yeem ua rau cov laug cam tsis zoo.Kev siv cov khoom siv granite hauv PCB drilling thiab milling tshuab tuaj yeem txo qhov kev pheej hmoo ntawm cov laug cam vim EMI.

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

Hauv kev xaus, kev siv cov khoom siv granite hauv PCB drilling thiab milling tshuab yog ib qho txiaj ntsig zoo ntawm kev txo EMI qib thiab kev pheej hmoo ntawm cov laug cam.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.Lub kav ntev thiab tsis kam hnav thiab tsim kua muag ua rau cov khoom siv granite yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm hnyav ntawm PCB drilling thiab milling tshuab.Cov neeg tsim khoom uas suav nrog cov khoom siv granite hauv lawv cov tshuab tuaj yeem xyuas kom lawv cov neeg siv khoom tau txais cov tshuab ruaj khov thiab txhim khu kev qha uas ua tau zoo.
