Inqubo ye-PCB Design nenqubo yokukhiqiza inezinqubo eziningi ezingama-20,uthini olumpofuEbhodini lesekethe kungaholela kulayini sandhole, ukuwa kwentambo, amazinyo enja emugqa, umugqa wesifunda esivulekile, umugqa we-line sand hole; I-Pore Copper Thin Hole Engathi sína ngaphandle kwethusi; Uma ithusi lomgodi libale libucayi, ithusi lomgodi ngaphandle kwethusi; I-DeTin ayihlanzekile (ukubuyisa ama-times amahlandla azothinta i-coating detin ayihlanzekile) nezinye izinkinga zekhwalithi, ukuze ukuhlangana kwe-tin empofu kuvame ukusho ukuthi isidingo sokuvula kabusha noma sichithe umsebenzi owedlule, kudingeka ukuthi sibuyise. Ngakho-ke, embonini yePCB, kubaluleke kakhulu ukuqonda izimbangela ze-tin empofu

Ukubonakala kwe-tin empofu kuhlobene nokuhlanzeka kwePCB angenalutho yebhodi elingaphezulu. Uma kungekho ukungcoliswa, ngeke kube khona uthini ompofu. Okwesibili, umthengisi ngokwawo awonakele, izinga lokushisa nokunye. Ngemuva kwalokho ibhodi yesekethe ephrintiwe ibonakala ikakhulukazi kumaphuzu alandelayo:

1. Kukhona ukungcola kwezinhlayiyana epusheni yokuhlangana kwepuleti, noma kukhona izinhlayiya zokugaya ezishiywe ebusweni belayini ngesikhathi senqubo yokukhiqiza ye-substrate.

9. Indawo enkulu engaba khona ayikwazi ukukhishwa, indawo yebhodi inobomvu obumnyama obumnyama noma obomvu, uhlangothi olulodwa lwe-coati luphelele, uhlangothi olulodwa lwe-coating lubi
