Tasirin PCB Vias akan Siginar Sauri Mai Sauri

A cikin watsa siginar sauri mai sauri, vias yana gabatar da tasirin lantarki daban-daban, tare da ƙarfin parasitic da inductance na parasitic sune manyan abubuwan da ke damun su.

Ƙarfin Parasitic da Ruɗewar Sigina

Ƙarfin parasitic yana faruwa ne sakamakon hanyar sadarwa ta bango da ke hulɗa da kayan jan ƙarfe da na dielectric da ke kewaye. Wannan tasirin yana rage lokacin tashi da faɗuwar siginar, yana haifar da karkacewar sigina da ƙaruwar jinkirin watsawa. Misali, a cikin tsarin watsawa na dijital mai sauri na 10Gbps, ƙarfin parasitic na iya haifar da jinkiri na goma na picoseconds, wanda hakan na iya haifar da kurakuran bayanai.

Tsarin Haɗakarwa da Nuna Sigina

Inductance na parasitic yana tasowa yayin da wutar lantarki ke wucewa ta hanyoyin sadarwa, yana samar da filayen maganadisu marasa so. Wannan tasirin na iya haifar da nuna sigina, canza girman sigina da kuma shafar ingancin sigina. A mitoci na GHz, inductance na parasitic yana haifar da ƙarar sigina mai tsanani, ƙara yawan kuskuren bit (BER) da kuma lalata aikin tsarin gabaɗaya.

Rashin daidaituwar Impedance

Tunda hanyoyin sadarwa suna haifar da katsewa a cikin layukan watsawa na PCB, rashin daidaiton impedance na iya haifar da tunani mara so da matsalolin daidaiton sigina. A cikin PCBs masu layi da yawa, rashin daidaiton impedance yana ƙara bayyana, wanda ke sa kulawa ta hanyar ƙira ta zama mahimmanci don kiyaye daidaiton sigina mai sauri.
