Muri rusange, ibintu bigira ingaruka kubiranga PCB ni: uburebure bwa dielectric H, uburebure bwumuringa T, ubugari bwumurongo W, intera yumwanya, dielectric ihoraho Er yibikoresho byatoranijwe kubirindiro, nubunini bwa mask yagurishijwe.

Muri rusange, uko ubunini bwa dielectric nuburinganire bwumurongo, niko agaciro kangana;nini ya dielectric ihoraho, uburebure bwumuringa, ubugari bwumurongo, hamwe nubugari bwa masike yubunini, ntoya agaciro ka impedance.

Iya mbere: uburebure buciriritse, kongera umubyimba wo hagati birashobora kongera impedance, no kugabanya umubyimba wo hagati bishobora kugabanya impedance;preregs zitandukanye zifite ibintu bitandukanye bya kole hamwe nubunini.Umubyimba nyuma yo gukanda ujyanye nuburinganire bwikinyamakuru nuburyo bwo gukanda;kubwoko ubwo aribwo bwose bwakoreshejwe, birakenewe kubona ubunini bwurwego rwitangazamakuru rushobora kubyazwa umusaruro, rufasha kubara ibishushanyo mbonera, hamwe nubuhanga bwubuhanga, gukanda ibyapa, kugenzura Tolerance yinjira nurufunguzo rwo kugenzura ubunini bwitangazamakuru.

Icyakabiri: ubugari bwumurongo, kongera ubugari bwumurongo birashobora kugabanya impedance, kugabanya ubugari bwumurongo bishobora kongera impedance.Igenzura ryubugari bwumurongo rigomba kuba muburyo bwo kwihanganira +/- 10% kugirango ugere ku kugenzura inzitizi.Ikinyuranyo cyumurongo wibimenyetso kigira ingaruka kumurongo wose wikizamini.Inzitizi yacyo imwe ni ndende, ituma imiterere yose yumurongo idahwanye, kandi umurongo wa impedance ntiwemerewe gukora Umurongo, icyuho ntigishobora kurenga 10%.Ubugari bwumurongo bugenzurwa cyane cyane no kugenzura.Kugirango tumenye ubugari bwumurongo, ukurikije umubare wuruhande rwurupapuro rwinshi, ikosa ryo gushushanya urumuri, hamwe nikosa ryo kwimura, firime yimikorere irasubizwa inzira kugirango ihuze ubugari bwumurongo usabwa.

Icya gatatu: uburebure bwumuringa, kugabanya uburebure bwumurongo birashobora kongera impedance, kongera uburebure bwumurongo bishobora kugabanya inzitizi;uburebure bwumurongo burashobora kugenzurwa no gushushanya cyangwa guhitamo ubunini bujyanye nibikoresho fatizo byumuringa.Kugenzura umubyimba wumuringa urasabwa kuba umwe.Shunt block yongewe kumurongo wibikoresho bito hamwe ninsinga zitaruye kugirango ziringanize umuyaga kugirango wirinde umubyimba wumuringa utaringaniye kuri wire kandi bigira ingaruka kumasaranganya yumuringa cyane kuri cs na ss.Birakenewe kurenga ikibaho kugirango ugere ku ntego yuburinganire bwumuringa kumpande zombi.

Icya kane: guhoraho kwa dielectric, kongera dielectric ihoraho birashobora kugabanya impedance, kugabanya dielectric ihoraho bishobora kongera impedance, guhora dielectric bigenzurwa cyane nibikoresho.Ihoraho rya dielectric yamasahani atandukanye iratandukanye, ifitanye isano nibikoresho bisigara bikoreshwa: dielectric ihoraho ya plaque ya FR4 ni 3.9-4.5, izagabanuka niyongera ryinshuro zikoreshwa, naho dielectric ihoraho ya plaque ya PTFE ni 2.2 - Kugirango ubone ibimenyetso bihanitse hagati ya 3.9 bisaba agaciro gakomeye, bisaba dielectric ihoraho.

Icya gatanu: ubunini bwa mask yo kugurisha.Gucapa mask yo kugurisha bizagabanya kwihanganira urwego rwinyuma.Mubihe bisanzwe, gucapa mask imwe yo kugurisha irashobora kugabanya igabanuka rimwe ryarangiye kuri 2 oms, kandi irashobora gutuma itandukaniro ritandukana na 8 oms.Gucapa inshuro ebyiri igabanuka ryikubye kabiri inshuro imwe.Iyo ucapye inshuro zirenze eshatu, agaciro ka impedance ntigahinduka.
