Thaum PCB drilling thiab milling, qhov kub hloov pauv ntawm granite ntsiab lus yog dab tsi?

Granite cov ntsiab lus tau dhau los ua neeg nyiam hauv kev tsim thiab kev tsim kho ntawm PCB drilling thiab milling tshuab.Qhov no yog vim lawv muaj peev xwm tiv taus qhov kub thiab txias tsim thaum lub sij hawm machining txheej txheem yam tsis poob lawv cov qauv kev ncaj ncees.Kev siv cov khoom siv granite hauv PCB drilling thiab milling tshuab txhim kho qhov tseeb, precision thiab ceev ntawm cov txheej txheem ua rau cov khoom zoo kawg.

Qhov kub hloov pauv ntawm granite ntsiab lus siv hauv PCB drilling thiab milling tshuab yog nyob ntawm ntau yam.Cov yam tseem ceeb no muaj xws li hom granite siv, lub thickness ntawm cov khoom siv granite, qhov drilling los yog milling ceev, thiab qhov tob thiab qhov loj ntawm lub qhov yog machined.

Feem ntau, granite muaj cov coefficient tsawg ntawm thermal expansion, uas txhais tau hais tias nws yuav tiv taus deformation thiab kev puas tsuaj los ntawm qhov kub thiab txias.Tsis tas li ntawd, granite muaj lub peev xwm siab thermal, uas tso cai rau nws nqus cua sov thiab tswj qhov kub thiab txias.Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv PCB drilling thiab milling tshuab, qhov kub siab yog tsim thaum lub sij hawm machining txheej txheem.

Feem ntau cov khoom siv granite siv hauv PCB drilling thiab milling tshuab muaj qhov sib txawv ntawm qhov kub ntawm 20 ℃ txog 80 ℃.Txawm li cas los xij, qhov ntau yam no tuaj yeem sib txawv nyob ntawm seb hom granite siv.Piv txwv li, dub granite, uas muaj peev xwm thermal ntau dua, tuaj yeem tiv taus qhov kub thiab txias dua piv rau cov xim sib dua ntawm granite.

Ntxiv rau qhov sib txawv ntawm qhov kub thiab txias, lub thickness ntawm cov granite tseem yog ib qho tseem ceeb uas yuav tau xav txog.Thicker granite cov ntsiab lus zoo dua tuaj yeem nqus cua sov thiab tswj qhov kub thiab txias thaum lub sijhawm machining txheej txheem.Qhov no ua kom ntseeg tau tias qhov tseeb thiab qhov tseeb ntawm PCB drilling thiab milling tshuab yog khaws cia txawm tias tom qab siv ntev.

Qhov drilling lossis milling ceev kuj yog ib qho tseem ceeb uas yuav tsum tau xav txog thaum siv granite ntsiab hauv PCB drilling thiab milling tshuab.Kev kub siab drilling lossis milling nrawm tsim kom muaj cua sov ntau, uas tuaj yeem ua rau muaj kev puas tsuaj rau cov khoom siv granite.Yog li ntawd, nws yog ib qho tseem ceeb los tswj qhov ceev ntawm lub tshuab kom ntseeg tau tias qhov kub thiab txias ntawm qhov sib txawv ntawm cov khoom siv granite yog khaws cia.

Hauv kev xaus, kev siv cov ntsiab lus granite tau hloov pauv ntawm PCB drilling thiab milling txheej txheem.Lawv muaj peev xwm tiv taus qhov kub thiab txias yam tsis muaj kev puas tsuaj.Qhov kub hloov pauv ntawm granite ntsiab siv hauv PCB drilling thiab milling tshuab yog nruab nrab ntawm 20 ℃ to 80 ℃, nyob ntawm qhov tuab thiab hom granite siv.Nrog rau cov ntaub ntawv no, engineers thiab cov kws tshaj lij tuaj yeem xaiv qhov zoo granite caij rau lawv cov PCB drilling thiab milling tshuab kom ua tau zoo thiab ua tiav cov khoom zoo kawg.
