Mugushushanya umuvuduko wihuse wa PCB, guhuza impedance nikimwe mubintu byashushanyije.Agaciro ka impedance gafite umubano wuzuye nuburyo bwo gukoresha insinga, nko kugenda hejuru yubuso (microstrip) cyangwa urwego rwimbere (stripline / double stripline), intera iri hagati yicyerekezo (power power cyangwa layer layer), ubugari bwinsinga, ibikoresho bya PCB , nibindi Byombi bizagira ingaruka kubiranga impedance agaciro k'umurongo.
Nukuvuga ko agaciro ka impedance gashobora kugenwa nyuma yo gushakisha.Mubisanzwe, porogaramu yo kwigana ntishobora kuzirikana ibintu bimwe na bimwe byogukoresha hamwe nimbogamizi zidahagarara kubera kugabanuka kwimiterere yumuzunguruko cyangwa imibare ya algorithm yakoreshejwe.Muri iki gihe, gusa abarangiza (kurangiza), nkurwanya urukurikirane, barashobora kubikwa ku gishushanyo mbonera.Kugabanya ingaruka zo guhagarikwa mukurinda inzitizi.Igisubizo nyacyo cyikibazo nukugerageza kwirinda guhagarika inzitizi mugihe wiring.
