Cov tshuab PCB drilling thiab milling yog cov cuab yeej tseem ceeb hauv kev tsim cov ntawv luam tawm Circuit Board, pab tsim cov qhov thiab cov qauv tsim nyog ntawm PCB. Kev ua tau zoo tag nrho ntawm cov tshuab no nyob ntawm ntau yam, suav nrog kev tsim cov khoom granite siv hauv lawv txoj kev tsim kho. Los ntawm kev ua kom zoo dua qhov kev tsim qauv ntawm cov khoom no, nws muaj peev xwm txhim kho qhov ua tau zoo thiab qhov tseeb ntawm cov tshuab no. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qee txoj hauv kev los txhim kho kev ua tau zoo ntawm PCB drilling thiab milling tshuab los ntawm kev ua kom zoo dua qhov kev tsim qauv granite.
Granite yog ib yam khoom siv nrov rau kev tsim cov tshuab PCB drilling thiab milling vim nws qhov siab tawv, coefficient thermal expansion qis, thiab ruaj khov zoo. Txawm li cas los xij, kev tsim cov khoom granite tuaj yeem cuam tshuam rau kev ua haujlwm tag nrho ntawm lub tshuab. Los ntawm kev ua qee qhov kev hloov pauv tseem ceeb, nws muaj peev xwm txhim kho kev ua haujlwm ntawm lub tshuab hauv ntau txoj kev.
Ua ntej, cov duab thiab qhov loj ntawm cov khoom granite tuaj yeem muaj feem cuam tshuam loj rau kev ua haujlwm ntawm lub tshuab. Qhov tuab ntawm cov khoom granite yuav tsum tau ua kom zoo tshaj plaws kom ntseeg tau tias lawv muab kev txhawb nqa txaus rau lub tshuab thaum tseem txo qhov hnyav tag nrho. Tsis tas li ntawd, qhov loj thiab cov duab ntawm cov khoom granite yuav tsum tau tsim los txo qhov kev co thiab txhim kho qhov ruaj khov ntawm lub tshuab. Qhov no tuaj yeem ua tiav los ntawm kev tsim cov khoom nrog qee qhov geometry thiab qhov loj me kom ua tiav qhov siab tshaj plaws resonance zaus, uas txhawb kev ruaj khov thiab txo qhov cuam tshuam ntawm cov rog sab nraud rau lub tshuab.
Lwm yam tseem ceeb hauv kev ua kom zoo dua qhov kev tsim cov khoom granite yog kom txo cov coefficient thermal expansion. Thermal expansion tuaj yeem ua rau lub tshuab tawm ntawm txoj kev xav tau thaum lub sijhawm drilling thiab milling, uas tuaj yeem cuam tshuam tsis zoo rau qhov tseeb ntawm lub tshuab. Kev tsim cov khoom nrog cov coefficient thermal expansion qis tuaj yeem pab txo cov teebmeem no thiab txhim kho qhov tseeb ntawm lub tshuab.
Lwm qhov kev hloov pauv tseem ceeb uas yuav tsum xav txog yog qhov ua tiav ntawm cov khoom granite. Qhov ua tiav ntawm cov khoom txiav txim siab qhov sib txhuam ntawm cov khoom thiab lub tshuab, thiab tuaj yeem cuam tshuam rau qhov du ntawm lub tshuab txav mus los. Los ntawm kev siv cov khoom granite polished, nws muaj peev xwm txo qhov sib txhuam thiab txhim kho qhov du ntawm lub tshuab txav mus los. Qhov no tuaj yeem txhim kho qhov tseeb ntawm lub tshuab los ntawm kev txo qhov yuav tshwm sim ntawm kev hloov pauv hauv cov txheej txheem drilling thiab milling.
Xaus lus, kev ua kom zoo dua ntawm kev tsim cov khoom granite hauv PCB drilling thiab milling tshuab tuaj yeem muaj kev cuam tshuam loj rau lawv cov kev ua tau zoo. Los ntawm kev xav txog cov yam xws li cov duab thiab qhov loj me, thermal expansion coefficient, thiab qhov tiav ntawm qhov chaw, nws muaj peev xwm txhim kho qhov ua tau zoo thiab qhov tseeb ntawm cov tshuab no. Kev txhim kho kev ua tau zoo ntawm cov tshuab no tuaj yeem ua rau muaj kev tsim khoom ntau dua thiab txo cov nqi, ua rau lawv yog qhov kev nqis peev zoo rau txhua qhov chaw tsim khoom PCB.
