Vim li cas impollance xav tau rau ntau txheej pcb Circuit Coffs?
Cov laj thawj rau kev tsim kho tsim ntawm ntau-txheej pcb Circuit Coffic me tsuas yog suav nrog cov hauv qab no:
1. Txhim kho cov teeb liab kev sib txuam yog qhov tseem ceeb hauv kev sib kis ntawm cov teeb meem digital cov cim thiab cov teeb meem analog. Qhov kev ntsuas teeb liab zoo tshaj plaws uas yuav tsum muaj kev sib luag ntawm cov hauv paus thiab load xaus, ua tiav impedance txuam. Qhov no tuaj yeem txo cov paib kev xav, kom muaj teeb liab zoo, thiab zam cov teeb meem xws li teeb liab distortion thiab crosstalk.
2. Nce Circuit Court tseem muaj cov qauv tsim muaj cov qauv tsim los npaj cov teeb meem zoo thaum lub teeb meem zoo rau cov miniaturized thiab cov khoom siv hluav taws xob zoo.
3. Ua kom zoo rau lub hwj huam faib khoom, muaj zog rau cov suab nrov thiab muaj peev xwm txhim kho lub zog hluav taws xob, uas tsis yog txhim kho kev ruaj khov thiab kev ntseeg tau ntawm cov kab ke.
4. Txhawb cov tshuab tsim qauv ntau zaus yuav tsum tau tsim cov cim hluav taws xob sib txawv, suav nrog cov cim hluav taws xob sib txawv raws li cov cim kev tswj hwm kom tau raws ntau yam tsim yuav tsum tau.
5. Tswj cov khoom lag luam zoo ntawm cov paib kis mob muaj ntau yam kev hloov pauv hauv cov khw muag khoom PCB. Txhawm rau txhim kho lawv tus nqi xa khoom, nws yog qhov tsim nyog los nce lawv zaus. Yog tias lub Circuit Court nws tus kheej yog cuam tshuam los ntawm cov lus xws li etching, stack thickness, thiab cov khoom siv hlau tsis zoo, ua rau muaj cov cim kev hloov pauv thiab txo qis hauv cov kev ua tau zoo ntawm Circuit Court Board. Yog li ntawd, nws yog ib qho tsim nyog los tswj tus nqi impedance nyob rau hauv ib tug ntau.
