PCB drilling thiab milling tshuab yog cov cuab yeej tseem ceeb siv hauv kev tsim cov ntawv luam tawm Circuit Board (PCBs).Cov tshuab no siv cov cuab yeej ua teb uas tshem tawm cov khoom siv los ntawm PCB substrate siv cov kev sib hloov ceev ceev.Txhawm rau kom ntseeg tau tias cov tshuab no ua haujlwm zoo thiab ua haujlwm tau zoo, nws yog qhov tseem ceeb kom muaj cov khoom siv tshuab ruaj khov thiab muaj zog, xws li granite siv rau lub tshuab txaj thiab kev txhawb nqa.
Granite yog cov khoom siv nrov siv hauv kev tsim kho ntawm PCB laum thiab tshuab milling.Lub pob zeb ntuj no muaj cov khoom siv zoo heev thiab cov khoom siv thermal uas ua rau nws yog cov khoom siv zoo tshaj plaws rau kev tsim cov khoom siv tshuab.Hauv particular, granite muaj siab nruj, siab zog, tsis tshua muaj thermal expansion, thiab zoo heev stability.Cov khoom no xyuas kom meej tias lub tshuab tseem ruaj khov thiab tsis muaj kev vibration thaum lub sijhawm ua haujlwm, ua rau muaj qhov tseeb thiab ua haujlwm tau zoo.
Qhov cuam tshuam ntawm granite Cheebtsam ntawm tag nrho dynamic stability ntawm PCB drilling thiab milling tshuab tuaj yeem raug soj ntsuam los ntawm ntau txoj kev.Ib txoj hauv kev siv ntau tshaj plaws yog finite element tsom xam (FEA).FEA yog cov txheej txheem ua qauv uas suav nrog kev faib lub tshuab thiab nws cov khoom rau hauv cov khoom me me, tswj tau ntau dua, uas yog tom qab ntawd tshuaj xyuas siv cov tshuab computer algorithms.Cov txheej txheem no pab ntsuas tus cwj pwm dynamic ntawm lub tshuab thiab kwv yees seb nws yuav ua li cas nyob rau hauv ntau yam kev thauj khoom.
Los ntawm FEA, qhov cuam tshuam ntawm granite Cheebtsam ntawm lub tshuab kev ruaj ntseg, kev co, thiab resonance yuav raug soj ntsuam kom raug.Qhov tawv thiab lub zog ntawm granite xyuas kom meej tias lub tshuab tseem ruaj khov nyob rau hauv ntau yam kev khiav hauj lwm, thiab cov thermal expansion qis kom ntseeg tau tias lub tshuab qhov tseeb yog khaws cia nyob rau hauv ntau qhov kub thiab txias.Tsis tas li ntawd, cov khoom vibration-damping ntawm granite txo cov tshuab kev co, ua rau kev txhim kho kev ua haujlwm thiab raug.
Ntxiv rau FEA, kev kuaj lub cev kuj tseem tuaj yeem ua rau ntsuas qhov cuam tshuam ntawm granite Cheebtsam ntawm tag nrho cov dynamic stability ntawm PCB drilling thiab milling tshuab.Cov kev ntsuam xyuas no suav nrog kev siv lub tshuab rau ntau yam kev co thiab kev thauj khoom thiab ntsuas nws cov lus teb.Cov txiaj ntsig tau txais tuaj yeem siv los kho lub tshuab kom zoo thiab ua txhua yam kev hloov kho tsim nyog los txhim kho nws txoj kev ruaj ntseg thiab kev ua haujlwm.
Hauv kev xaus, cov khoom siv granite ua lub luag haujlwm tseem ceeb hauv kev txhim kho tag nrho cov kev ruaj ntseg ntawm PCB drilling thiab milling tshuab.Lawv muab cov khoom zoo heev thiab cov khoom siv thermal uas ua kom lub tshuab ruaj khov thiab tsis muaj kev vibration thaum lub sijhawm ua haujlwm, ua rau kev txhim kho kev ua haujlwm thiab raug.Los ntawm FEA thiab kev kuaj lub cev, qhov cuam tshuam ntawm granite Cheebtsam ntawm lub tshuab kev ruaj ntseg thiab kev ua haujlwm tuaj yeem raug soj ntsuam kom raug, kom ntseeg tau tias lub tshuab ua haujlwm ntawm qib siab.
