Lub Circuit Court boardyog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, ua tus choj txuas rau ntau yam khoom siv. Thiab ib qho ntawm cov khoom tseem ceeb tshaj plaws yog PCB. Yog li, PCB yog dab tsi?
PCB hais txog cov txheej txheem ntawm kev tsim cov khoom siv hluav taws xob thiab ntau yam khoom siv ntawm cov khoom siv hluav taws xob uas siv cov luam ntawv conductive. Qhov tshwm sim ntawm PCB circuit boards yog tsuas yog los hloov cov txheej txheem ntawm kev siv cov ntawv xov hlau, yog li txhim kho qhov tseeb thiab kev ntseeg siab ntawm Circuit Board.
Cov khoom tseem ceeb ntawm PCB Circuit Board tau muab faib ua cov hauv qab no:
1. Insulated substrate: Cov iav fiber ntau lossis cov khoom siv ceramic feem ntau yog siv los ua cov txheej hauv qab ntawm PCB Circuit Board. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv kev poob tam sim no thiab tiv thaiv cov khoom ntawm lub rooj tsav xwm hauv Circuit Court kom paub meej tias tag nrho cov haujlwm.
2. Cov kab hluav taws xob: Hais txog cov kab hlau uas tau teem rau ntawm lub rooj tsav xwm PCB. Lawv feem ntau yog ua los ntawm cov ntawv ci tooj liab, uas muaj ib qho kev ntxhib los mos thiab yooj yim txiav finely. Cov kab hluav taws xob yog cov khoom tseem ceeb ntawm PCB pawg thawj coj saib, thiab lawv cov xov hluav taws xob thiab kev sib txuas ncaj qha cuam tshuam rau kev ua haujlwm ntawm lub rooj tsav xwm Circuit Court.
3. Surface mount: yog hais txog cov khoom uas tau teem rau ntawm lub rooj tsav xwm PCB. Cov khoom no feem ntau yog tsim los ntawm cov khoom me me xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, uas tuaj yeem ncaj qha mus rau lub rooj tsav xwm PCB los ntawm qhov chaw mount. Txoj kev sib dhos no zoo heev txhim kho qhov ua tau zoo thiab qhov tseeb ntawm lub rooj tsav xwm Circuit Court.
