4 Layer ENIG FR4 Akhungu Oikidwa M'manda Kudzera pa PCB
Akhungu Anaikidwa M'manda Kudzera pa PCB
PCB kudzera vias akhoza kugawidwa kudzera kudzera, akhungu kudzera ndi m'manda kudzera.Blind burrow PCBs ikhoza kukhala yankho mukafuna kuyika PTH vias okwanira pa bolodi koma malo ndi ochepa.Miyendo yakhungu imagwiritsidwa ntchito kulumikiza zigawo za PCB mkati mwa malire.Akhungu kudzera ndi electroplated kudzera kuti zikugwirizana wosanjikiza mmodzi wakunja kwa mmodzi kapena angapo amkati zigawo.M'manda vias ndi electroplated vias kulumikiza zigawo ziwiri kapena kuposa zamkati koma osagwirizana ndi wosanjikiza akunja.
Ubwino Wa Akhungu Okwiriridwa Kudzera pa PCB
1. Malire a kachulukidwe a mawaya ndi ma padi mumapangidwe amatha kukumana popanda kuwonjezera kuchuluka kwa zigawo kapena kukula kwa bolodi
2. Chepetsani gawo la gawo la PCB
Akhungu kudzera / kukwiriridwa kudzera pa PCB kuti akwaniritse kachulukidwe ka board popanda kuwonjezera kuchuluka kwa zigawo kapena kukula kwa bolodi.Chifukwa chake, ma vias akhungu / okwiriridwa amagwiritsidwa ntchito mu HDI PCBs.Nthawi zambiri amagwiritsidwa ntchito pama foni am'manja, kulumikizana opanda zingwe, MID.Kabuku.
