Yog tias muaj kev thauj khoom siab lossis kev ua haujlwm ceev ceev, cov khoom siv granite PCB drilling thiab milling tshuab puas yuav tshwm sim thermal stress lossis thermal fatigue?

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

Txawm li cas los xij, qee qhov kev txhawj xeeb tau raug tsa txog qhov ua tau ntawm kev ntxhov siab thermal lossis thermal qaug zog tshwm sim hauv cov khoom granite ntawm PCB drilling thiab milling tshuab thaum lub sijhawm thauj khoom siab lossis kev ua haujlwm ceev.

Kev ntxhov siab ntawm cov cua sov tshwm sim thaum muaj qhov sib txawv ntawm qhov kub thiab txias ntawm cov khoom sib txawv. Nws tuaj yeem ua rau cov khoom nthuav dav lossis cog lus, ua rau deformation lossis tawg. Kev qaug zog ntawm cov cua sov tshwm sim thaum cov khoom raug cua sov thiab txias ntau zaus, ua rau nws tsis muaj zog thiab thaum kawg ua tsis tiav.

Txawm hais tias muaj cov kev txhawj xeeb no los xij, nws tsis zoo li tias cov khoom granite ntawm lub tshuab PCB drilling thiab milling yuav ntsib kev ntxhov siab thermal lossis thermal qaug zog thaum lub sijhawm ua haujlwm ib txwm. Granite yog ib yam khoom siv ntuj uas tau siv rau ntau pua xyoo hauv kev tsim kho thiab engineering, thiab nws tau ua pov thawj tias yog cov khoom siv txhim khu kev qha thiab ruaj khov.

Tsis tas li ntawd xwb, tus qauv tsim ntawm lub tshuab xav txog qhov muaj peev xwm ua rau muaj kev ntxhov siab thermal lossis kev qaug zog thermal. Piv txwv li, cov khoom feem ntau raug txheej nrog ib txheej tiv thaiv kom txo qhov cuam tshuam ntawm kev hloov pauv kub. Lub tshuab kuj tseem muaj cov tshuab cua txias ua ke los tswj qhov kub thiab tiv thaiv kom tsis txhob kub dhau.

Xaus lus, kev siv granite rau cov khoom ntawm PCB drilling thiab milling tshuab yog qhov kev xaiv uas tau ua 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 thermal lossis thermal qaug zog, kev tsim qauv ntawm lub tshuab coj cov yam no mus rau hauv tus account thiab ua rau lawv tsis zoo li yuav tshwm sim. Kev siv granite hauv PCB drilling thiab milling tshuab yog qhov kev xaiv zoo thiab muaj kev nyab xeeb rau kev lag luam hluav taws xob.
