Granite yog cov khoom xaiv rau lub hauv paus ntawm PCB drilling thiab milling tshuab vim nws cov rigidity siab, stability, thiab tsawg thermal expansion coefficient. Txawm li cas los xij, raws li thev naus laus zis nce qib thiab qhov kev thov rau cov nqi tsim nyog thiab kev ua haujlwm siab PCB tshuab nce, cov kws tshawb fawb thiab cov tuam txhab tau tshawb nrhiav cov ntaub ntawv tshiab uas tuaj yeem hloov granite.
Ib qho kev cog lus zoo tshaj plaws rau granite yog hluavtaws granite. Synthetic granite yog tsim los ntawm kev sib xyaw ntawm epoxy resin thiab quartz aggregates. Cov khoom siv hluavtaws muaj cov khoom zoo ib yam li granite, xws li siab tawv, tsis tshua muaj thermal expansion, thiab zoo heev damping yam ntxwv. Cov khoom siv kuj tseem tiv taus corrosion thiab tshuaj lom neeg, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv nyob rau hauv ib puag ncig corrosive heev ntawm PCB drilling thiab milling tshuab.
Lwm cov khoom siv uas tuaj yeem hloov tau granite yog aluminium composite panels. Cov vaj huam sib luag no muaj ob daim ntawv txhuas uas txuas nrog lub hauv paus yas. Cov panels muaj qhov nruj thiab nruj, uas ua rau lawv zoo tagnrho rau kev siv los ua lub hauv paus ntawm PCB drilling tshuab. Cov khoom siv yog lub teeb yuag thiab yooj yim rau tshuab, ua rau nws yog ib qho kev xaiv zoo nkauj rau cov tuam txhab nrhiav kom txo qhov hnyav ntawm lawv cov tshuab thiab txhim kho lawv cov khoom tsim tau.
Ntxiv nrog rau cov khoom siv hluavtaws granite thiab aluminium composite panels, lwm cov ntaub ntawv xws li carbon fiber composites thiab high-performance polymers kuj tau tshawb fawb siv rau hauv PCB drilling thiab milling tshuab. Cov ntaub ntawv no muaj kev nruj nruj, tsis tshua muaj thermal expansion, thiab cov cuab yeej zoo heev, ua rau lawv zoo tagnrho rau kev siv cov tshuab ua haujlwm siab.
Thaum siv cov ntaub ntawv tshiab hauv kev tsim kho PCB drilling thiab milling tshuab muaj peev xwm txhim kho kev ua tau zoo thiab txo tus nqi ntawm cov tshuab no, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov ntaub ntawv no tuaj nrog lawv tus kheej cov teeb meem. Piv txwv li, kev siv cov hluavtaws granite yuav xav tau kev hloov kho rau cov tshuab uas twb muaj lawm kom haum rau qhov sib txawv thermal expansion cov yam ntxwv ntawm cov khoom. Tsis tas li ntawd, kev siv cov khoom siv tshiab yuav xav tau kev hloov pauv ntawm cov txheej txheem tsim khoom, uas tuaj yeem ntxiv rau cov nqi tsim khoom.
Hauv kev xaus, thaum granite tau yog cov khoom ntawm kev xaiv rau lub hauv paus ntawm PCB drilling thiab milling tshuab tau ntau xyoo, muaj cov ntaub ntawv tshiab thiab zoo siab tau tsim uas tuaj yeem txhim kho kev ua tau zoo lossis txo tus nqi ntawm cov tshuab no. Cov neeg tsim khoom thiab cov kws tshawb fawb tseem tab tom tshawb nrhiav cov ntaub ntawv tshiab thiab thev naus laus zis kom ua tau raws li qhov xav tau ntawm kev lag luam PCB puas tau hloov zuj zus. Raws li kev siv tshuab txuas ntxiv mus, nws zoo li peb yuav pom kev hloov pauv ntawm kev siv cov ntaub ntawv tshiab hauv PCB drilling thiab milling tshuab.
