Abstract

A process for processing a printed circuit board with molten tin metal, which comprises: (1) putting the printed circuit board into a liquid tin processing furnace, and delaminating copper foil from the printed circuit board by a smashing and blending procedure while carbonizing the thermosetting plastics in the printed circuit board; (2) maintaining the blending of the carbonized printed circuit board, and separating the copper foil, thermosetting plastics and glass fibers by their differences in specific gravity; (2)-1-1 scraping off the floating thermosetting plastics and glass fibers by a dross skimming device; (2)-1-2 collecting the skimmed thermosetting plastics and glass fibers in a dross collection tank; (2)-2-1 destroying the volatile gases generated during carbonization of the thermosetting plastics by a burner; (2)-2-2 reintroducing the volatile gases, which are not completely destroyed by the burner, into a combustion chamber to convert the volatile gases into stable gases; (2)-3-1 periodically removing the separated copper foil at a fixed amount; (2)-3-2 collecting the removed copper foil in a metal collection tank. 4H).
