Tilmaamaha qaab dhismeedka PCB
1. Dielectric Layer (Dielectric): Waxaa loo isticmaalaa in lagu ilaaliyo dahaarka u dhexeeya xadadka iyo lakabyada, oo badanaa loo yaqaan substrate.
2. Shaashadda xariirta ah (Halyeeyad/Calaamadeynta/Sharashadda xariirta): Tani waa qayb aan muhiim ahayn.Shaqadeeda ugu weyn waa inay calaamadiso magaca iyo booska booska qayb kasta oo ka mid ah guddiga wareegga, kaas oo ku habboon dayactirka iyo aqoonsiga ka dib marka la isku daro.
3.Daawaynta dusha sare (SurtaceFinish): Maadaama dusha naxaasta si sahal ah ay oksaydhisku ugu jiraan deegaanka guud, laguma daasay karo (alxanka liidata), sidaa awgeed dusha naxaasta ah ee lagu qasaaray waa la ilaalin doonaa.Hababka ilaalinta waxaa ka mid ah HASL, ENIG, Immersion Silver, Immersion Tin, iyo alxanka alxanka (OSP).Hab kastaa wuxuu leeyahay faa'iidooyin iyo faa'iido darrooyin u gaar ah, oo si wadajir ah loogu tixraaco daaweynta dusha sare.
