Nyob rau hauv cov ntaub ntawv ntawm high load los yog high-ceev ua hauj lwm, puas PCB drilling thiab milling tshuab granite Cheebtsam tshwm thermal stress los yog thermal qaug zog?

PCB drilling thiab milling tshuab tau dav siv hauv kev lag luam hluav taws xob.Ib qho ntawm cov khoom siv feem ntau siv rau lub tshuab cov khoom yog granite.Granite yog cov khoom siv tawv thiab ruaj khov uas tuaj yeem tiv taus qhov hnyav thiab ua haujlwm ntawm kev kub ceev.

Txawm li cas los xij, qee qhov kev txhawj xeeb tau hais txog qhov muaj peev xwm ntawm thermal stress los yog thermal qaug zog tshwm sim nyob rau hauv granite Cheebtsam ntawm PCB drilling thiab milling tshuab thaum lub sij hawm siab load los yog high-ceev ua hauj lwm.

Thermal stress tshwm sim thaum muaj qhov sib txawv ntawm qhov kub ntawm qhov sib txawv ntawm cov khoom.Nws tuaj yeem ua rau cov khoom nthuav tawm lossis cog lus, ua rau deformation lossis tawg.Thermal qaug zog tshwm sim thaum cov khoom siv rov ua dua cov cua sov thiab cua txias, ua rau nws tsis muaj zog thiab nws thiaj li poob.

Txawm hais tias muaj kev txhawj xeeb no, nws tsis zoo li cov khoom siv granite ntawm PCB drilling thiab milling tshuab yuav muaj kev ntxhov siab lossis thermal qaug zog thaum lub sijhawm ua haujlwm.Granite yog cov khoom siv ntuj tsim uas tau siv ntau pua xyoo hauv kev tsim kho thiab kev tsim vaj tsev, thiab nws tau ua pov thawj tias yog cov khoom siv ruaj khov thiab ruaj khov.

Ntxiv mus, tus tsim ntawm lub tshuab yuav siv sij hawm mus rau hauv tus account lub peev xwm ntawm thermal stress los yog thermal qaug zog.Piv txwv li, cov khoom feem ntau yog coated nrog ib txheej tiv thaiv kom txo tau qhov cuam tshuam ntawm qhov kub thiab txias hloov.Lub tshuab kuj muaj cov tshuab ua cua txias los tswj qhov kub thiab txias thiab tiv thaiv overheating.

Hauv kev xaus, kev siv granite rau cov khoom ntawm PCB drilling thiab milling tshuab yog qhov kev xaiv pov thawj thiab txhim khu kev qha.Txawm hais tias muaj kev txhawj xeeb txog qhov muaj peev xwm ua rau muaj kev ntxhov siab los yog thermal qaug zog, kev tsim lub tshuab siv cov khoom no rau hauv tus account thiab ua rau lawv tsis zoo li tshwm sim.Kev siv granite hauv PCB drilling thiab milling tshuab yog qhov kev xaiv zoo thiab muaj txiaj ntsig zoo rau kev lag luam hluav taws xob.
