Dab tsi yog qhov cuam tshuam ntawm kev txheeb xyuas lub rooj tsav xwm hauv Circuit Court ntawm cov khoom siv thaum ua PCB?
Kev ruaj ntseg ntawm ntau- txheej txheej PCB cov txheej txheem yog qhov tseem ceeb cuam tshuam rau qhov tseeb qhov chaw ntawm txheej sab hauv. Nws kuj tseem yuav tsum tau xav txog qhov cuam tshuam ntawm thermal expansion coefficient ntawm substrate thiab tooj liab ntawv ci nyob rau hauv txheej txheej ntawm Multilayer PCB. Los ntawm kev txheeb xyuas cov khoom ntawm lub cev ntawm lub substrate siv, laminates muaj cov polymers, thiab nws cov qauv tseem ceeb yuav hloov ntawm qhov kub thiab txias, uas feem ntau hu ua iav hloov kub Tg.
Thaum lub sijhawm ua haujlwm ntawm BQC Circuit Board hauv Shenzhen, kev xaiv cov khoom siv raw kuj tseem ceeb heev. Peb yuav tsum ua nyob rau hauv - tsom xam qhov tob ntawm kev ua haujlwm ntawm cov khoom siv raw los xyuas kom meej tias cov khoom siv raw ua tau raws li cov kev xav tau ntawm kev txawj ntse thiab muab kev pabcuam rau kev ua haujlwm tom qab. Nyob rau hauv lub neej yav tom ntej, cov kev txawj ntse yuav txhim kho ntxiv, thiab nws txoj kev tsim khoom yuav ua tau zoo dua nyob rau lub sijhawm los xyuas kom meej tias tus qauv thiab qhov tseeb ntawm lub rooj tsav xwm Circuit Court tau ua raws li qhov yuav tsum tau ua.
