N'ihi na metal mkpụrụ, ọla kọpa na aluminum na-eji PCB, ma nwere dị iche iche ngwa;
Otú ọ dị, ọ bụrụ na anyị na-atụle ya site n'akuku nke PCB plating, anyị na-enweta a kpam kpam dị iche iche azịza:
PCB plating tumadi na-agụnye ọla kọpa, tin, nickel na gold plating.Copper plating bụ ihe dị mkpa nhazi technology na PCB n'ichepụta.
Dị ka ị maara, ọla kọpa plating nwere uru nke ọma eletriki conductivity, thermal conductivity, n'ibu malleability na na, ya bụ, ọla kọpa imikpu mgbe mkpọpu ala, electroplating dum PCB, na ndim circuit na ọla kọpa, nile nke na-iji hụ na eletriki conductivity ; Ke adianade do, ndị nkịtị plating ngwọta bụ CuSO4;
In short, the process goes like this: drilling - immersion copper-plating - wire-drawing - etching
