Mfundo zazikulu za PCB kapangidwe kogwirizana:

1, kuyanjana kwa bolodi la dera kumawonekera kwambiri pamagetsi amagetsi, ndipo mawonekedwe amagetsi amagetsi amatha kumvedwa ngati board board m’malo osiyanasiyana amagetsi atha kukhalabe ndi mphamvu yolumikizana ndikugwira bwino ntchito, choyambirira, kuthekera koyamba kumagulu amagetsi pamagetsi ndi m’lifupi waya, kutalika kwa waya kumapangitsa kuti waya azisindikizidwa, mawonekedwe a Inductance amatanthauzira kusokonekera kwamphamvu kwakanthawi kochepa pa board board, kotero kusankha koyenera kwa waya kungachepetse kusokonekera kwamagetsi.
2, kuwonjezera pa inductance, kusindikizidwa Kulumikizana kungakhudze pa dera bolodi Kulumikizana kumathandizanso inductance, monga wamba ndi ofanana kuyenda mzere, kuti tikhale ndi zotsatira za kuchepetsa inductance, mwagwirizana inductance ukuwonjezeka, koma downside ndi mawaya komanso kuonjezera kuchuluka kwa capacitance, kotero mu kapangidwe ka bolodi dera, ayenera malinga ndi momwe zinthu ziliri kusankha Kulumikizana wololera.
3, kuphatikiza pakungotchulapo kumene, kukopa ndi kutsogolera kwa bolodi kuyanjana, mtanda pakati pakufunika kutchera khutu kuderali ndikulumikizanabe, monga zingwe zomwe zatchulidwazi zingayese kupewa zingwe zazitali, ndikuyesera kulola mtunda pakati pa mzere ndi mzere, komanso waya wa mbendera ndi waya wapansi ndi chingwe chamagetsi sichidutsa, Ngati pali chingwe chazovuta kwambiri, mutha kuwonjezera chingwe chopondera kuti mupewe crosstalk, yomwe ingathenso kupondereza crosstalk.
