PCB impedance bivuga ibipimo byo kurwanya no kwitwara, bigira uruhare runini muguhinduranya amashanyarazi. Mubikorwa byumuzunguruko wa pcb, kuvura impedance ni ngombwa. Noneho uzi impamvu ikibaho cyumuzunguruko wa PCB gikeneye gukora impedance?

1, PCB yumuzunguruko wa PCB kugirango harebwe iyinjizwa ryibikoresho bya elegitoronike, imiyoboro yumuriro nigikorwa cyo kohereza ibimenyetso nyuma yo gushiramo, bityo bizakenera hasi impedance, nibyiza, birwanya munsi ya 1 × 10-6 kuri santimetero kare munsi.

2, Ikibaho cyumuzunguruko wa PCB mugikorwa cyo kubyara kugirango habeho kurohama umuringa, gusiga amabati (cyangwa isahani idafite amashanyarazi, cyangwa gutera amashyanyarazi ashyushye), guhuza ibicuruzwa hamwe nandi masoko atunganya umusaruro, hamwe nibikoresho byakoreshejwe muribi bice bigomba kwemeza ko munsi yumurwanya, muri gutegekanya kwemeza ko inzitizi rusange yubuyobozi bwumuzunguruko wa PCB iri hasi kugirango ihuze ibicuruzwa byujuje ubuziranenge, irashobora gukora mubisanzwe.

3, gutunganya ikibaho cya PCB nicyo gikunze guhura nibibazo mu musaruro wubuyobozi bwumuzunguruko wose, kandi niwo murongo wingenzi ugira ingaruka. Inenge nini yimiterere ya tin yamashanyarazi ni ibara ryoroshye (byombi byoroshye okiside cyangwa gusiba), kurigata nabi, bizatuma gusudira bigoye kubibaho byumuzunguruko, inzitizi nyinshi zitera amashanyarazi mabi cyangwa imikorere idahwitse yibikorwa byose.

4. ni byiza guhinduka, kugirango ibimenyetso bigoreka ibimenyetso, bigatuma imikorere yubuyobozi igabanuka, ugomba rero kugenzura agaciro ka impedance murwego runaka.
