Tilmaamaha qaab dhismeedka PCB
1. Khad adkaysi u adkaysata (Alxan u adkaysta/Mask): Dhammaan sagxadaha naxaasta ah maaha inay cunaan qaybo ka mid ah daasadaha, markaa meesha aan daasada lagu cunin waxa lagu daabici doonaa lakabka shay (sida caadiga ah resin epoxy) kaas oo ka sooca oogada naxaasta ka soocay daasad cunista ilaa iska ilaali iibka aan la iibin.Waxaa jira wareeg gaaban oo u dhexeeya xariiqyada qasacadaysan.Marka loo eego habab kala duwan, waxa loo qaybiyaa saliid cagaaran, saliid cas iyo saliid buluug ah.
2. Dielectric Layer (Dielectric): Waxaa loo isticmaalaa in lagu ilaaliyo dahaarka u dhexeeya xadadka iyo lakabyada, oo badanaa loo yaqaan substrate.
3. Daawaynta dusha sare (SurtaceFinish): Maadaama oogada naxaasta ay si sahal ah oksidhis ugu samaynayso deegaanka guud, lama daasay karo (alxanka liidata), sidaa awgeed waxa la ilaalinayaa naxaasta dusha sare ee lagu qasaaray.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.
