Txhawm rau txo cov teeb meem no, cais cov cim analog thiab digital ntawm cov txheej PCB sib txawv. Siv cov txheej txheem hauv av kom tsim nyog los tiv thaiv kev sib txuas ntawm cov teeb liab sib txawv. Ua raws li kev tiv thaiv thiab tswj kom muaj qhov sib txawv ntawm cov kab rhiab heev kom txo tau cov lus sib tham. Los ntawm kev txo qis suab nrov thiab kev sib tham sib tham, koj tuaj yeem ua tiav qhov pom tseeb, txhim khu kev qha ntau dua hauv koj tus qauv PCB.
5. Cheebtsam xaiv thiab tso
Ua tib zoo xaiv cov khoom siv thiab kev tso kawm yog qhov tseem ceeb rau kev pom zoo PCB prototyping. Xaiv cov khoom uas xav tau kev qhia tshwj xeeb thiab xyuas kom lawv npaj txhij rau kev tsim khoom. Xav txog yam xws li qhov loj me, qhov xav tau ntawm lub zog, thiab kev tswj xyuas thermal thaum lub sij hawm muab tso rau. Los ntawm kev xaiv thiab muab cov khoom sib xyaw ua ke, koj tuaj yeem txo cov teeb liab cuam tshuam, teeb meem thermal thiab teeb meem ntau lawm.
6. Optimize fais fab faib network
Kev faib hluav taws xob zoo yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm koj tus qauv PCB. Tsim kom muaj lub zog faib hluav taws xob zoo tshaj plaws kom txo tau qhov hluav taws xob poob qis, txo qis hluav taws xob poob, thiab ua kom lub zog ruaj khov rau cov khoom sib txawv. Tsim kom muaj qhov loj me ntawm cov kab hluav taws xob thiab cov vias los daws qhov xav tau tam sim no yam tsis muaj hluav taws xob ntau dhau. Los ntawm kev ua kom zoo dua lub zog faib hluav taws xob, koj tuaj yeem txhim kho kev ntseeg tau thiab kev ua tau zoo ntawm koj tus qauv PCB.
