Akwai “ka’idar chamfering” don PCB wiring, wato ya kamata a nisanci kusurwoyi masu kaifi da madaidaitan kusurwoyi a tsarin PCB, kuma ana iya cewa wannan ya zama daya daga cikin ma’auni na auna ingancin wayar, don haka me zai hana a tafi daidai kusurwoyin PCB?

Akwai manyan sakamako uku na motsi-kusurwar dama akan sigina:

1. Zai iya zama daidai da nauyin capacitive akan layin watsawa kuma yana jinkirta lokacin tashi.

2. Katsewar impedance zai haifar da tunanin sigina.

3. EMI wanda aka samar ta hanyar kusurwar dama.

Ainihin, wayoyin PCB suna da babban Angle, madaidaicin Angle zai sa faɗin layin canjin layin watsawa, wanda ke haifar da dakatarwar rashin ƙarfi, dakatarwar impedance zai nuna. Dangane da fa’ida da jinkirin tunani, superimpose akan asalin bugun bugun bugun jini don samun raƙuman ruwa, wanda ke haifar da rashin daidaituwa da rashin daidaiton siginar.

Saboda akwai haɗin kai, fil na na’ura, bambancin faɗin waya, lanƙwasa waya, da ramuka, dole juriya ta canza, don haka za a yi tunani.

Daidaita kusurwar dama ba lallai ba ne, amma ya kamata a kauce masa idan zai yiwu, saboda kulawa da cikakkun bayanai yana da mahimmanci ga kowane injiniya mai kyau. Kuma yanzu da’irar dijital tana haɓaka cikin hanzari, mitar siginar da za a sarrafa a nan gaba za ta karu sannu a hankali, waɗannan kusurwoyin dama na iya zama tushen matsalar.
