Cov tshuab drilling thiab milling PCB yog cov cuab yeej tseem ceeb siv rau hauv kev tsim cov ntawv luam tawm Circuit Board (PCBs). Cov tshuab no siv cov cuab yeej txiav rotary uas tshem tawm cov khoom siv los ntawm PCB substrate siv kev txav mus los ceev ceev. Yuav kom ntseeg tau tias cov tshuab no ua haujlwm tau zoo thiab ua haujlwm tau zoo, nws yog ib qho tseem ceeb kom muaj cov khoom siv tshuab ruaj khov thiab muaj zog, xws li granite siv rau lub txaj tshuab thiab cov qauv txhawb nqa.
Granite yog ib yam khoom siv nrov siv rau hauv kev tsim cov tshuab PCB thiab milling. Lub pob zeb ntuj no muaj cov khoom siv kho tshuab thiab thermal zoo heev uas ua rau nws yog ib yam khoom zoo tagnrho rau kev tsim cov khoom siv hauv tshuab. Tshwj xeeb, granite muaj kev ruaj khov siab, muaj zog siab, tsis tshua muaj thermal nthuav dav, thiab ruaj khov zoo heev. Cov khoom no ua kom lub tshuab ruaj khov thiab tsis muaj kev co thaum lub sijhawm ua haujlwm, ua rau muaj kev raug thiab kev ua haujlwm zoo dua.
Qhov cuam tshuam ntawm cov khoom granite rau qhov ruaj khov ntawm PCB drilling thiab milling tshuab tuaj yeem soj ntsuam los ntawm ntau txoj kev. Ib qho ntawm cov txheej txheem siv ntau tshaj plaws yog finite element analysis (FEA). FEA yog ib txoj kev ua qauv uas cuam tshuam nrog kev faib lub tshuab thiab nws cov khoom ua cov khoom me me, yooj yim dua, uas tom qab ntawd raug soj ntsuam siv cov algorithms computer zoo heev. Cov txheej txheem no pab soj ntsuam tus cwj pwm dynamic ntawm lub tshuab thiab kwv yees li cas nws yuav ua haujlwm nyob rau hauv ntau yam kev thauj khoom.
Los ntawm FEA, qhov cuam tshuam ntawm cov khoom granite rau lub tshuab qhov ruaj khov, kev co, thiab kev sib nqus tuaj yeem soj ntsuam tau meej. Qhov tawv thiab lub zog ntawm granite ua kom lub tshuab ruaj khov nyob rau hauv ntau yam kev ua haujlwm, thiab qhov nthuav dav thermal qis ua kom lub tshuab qhov tseeb raug tswj hwm ntawm ntau qhov kub thiab txias. Ntxiv mus, cov khoom siv vibration-damping ntawm granite txo qis lub tshuab qhov kev co, ua rau muaj kev ua haujlwm zoo dua thiab raug dua.
Ntxiv rau FEA, kev kuaj lub cev kuj tseem tuaj yeem ua tau los ntsuas qhov cuam tshuam ntawm cov khoom granite rau qhov ruaj khov ntawm PCB drilling thiab milling tshuab. Cov kev xeem no suav nrog kev ua rau lub tshuab raug 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 thiab ua txhua yam kev hloov kho tsim nyog los txhim kho nws qhov ruaj khov thiab kev ua tau zoo.
Xaus lus, cov khoom granite ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov ruaj khov ntawm PCB drilling thiab milling tshuab. Lawv muaj cov khoom siv kho tshuab thiab thermal zoo heev uas ua kom lub tshuab ruaj khov thiab tsis muaj kev co thaum lub sijhawm ua haujlwm, ua rau muaj kev ua haujlwm zoo dua thiab raug. Los ntawm FEA thiab kev sim lub cev, qhov cuam tshuam ntawm cov khoom granite rau lub tshuab qhov ruaj khov thiab kev ua tau zoo tuaj yeem soj ntsuam tau raws li qhov tseeb, kom ntseeg tau tias lub tshuab ua haujlwm ntawm qib zoo tshaj plaws.
