Mene ne halaye na kwamfyutar PCB biyu mai rufi da kwamiti mai zagaye da yawa da yadda ake rarrabe su? Bari mu bi masu samar da kwamitin PCBdon fahimta:
Double Layer PCB hukumar
Allon mai fuska biyu yana da wayoyi a duka ɓangarorin biyu Amma don amfani da ɓangarorin biyu na waya, dole ne ya zama akwai haɗin lantarki mai dacewa tsakanin ɓangarorin biyu.Wannan "gada" tsakanin da'irar ana kiranta ramin jagora (VIA) .Ramin jagora shine karamin rami a cikin PCB, wanda aka cika ko an rufe shi da karfe, ana iya haɗa shi da waya a bangarorin biyu.Saboda bangarori biyu suna da sau biyu na yanki guda ɗaya, kuma saboda ana iya haɗa wayoyi (wanda zai iya rauni a kusa da wani gefen), ya fi dacewa da da'irar da ke da rikitarwa fiye da rukuni guda.
