Kedu ọrụ nke PCB kpuchie ọla kọpa?

Ogwe sekit PCB n’ụdị ngwa eletriki na ngwa niile enwere ike ịhụ ebe niile, ntụkwasị obi nke bọọdụ sekit bụ nkwa dị mkpa iji hụ na arụ ọrụ dị iche iche, mana n’ọtụtụ bọọdụ sekit anyị na -ahụkarị nnukwu mpaghara mkpuchi ọla kọpa, sekit imewe. osisi nwere nnukwu ebe mkpuchi ọla kọpa.
