Abstract
The present invention provides a method and apparatus of recycling a printed circuit board for separating and retrieving a metallic material, which includes a printed metallic material, and an insulating material, both composing the printed circuit board. Both the metallic material and the insulating material, which are separated and retrieved, are possible for recycling. In the method for recycling the printed circuit board, hot filtration equipmentand resin-metal separation equipmentare used in hot filtration process P. The waste printed circuit boardis heated and force-filtered so that only the insulating materialpass through the filter. Then, the insulating materialand the metallic materialare separated and retrieved. It is preferred that the insulating body baseof the printed circuit boardas the waste printed circuit board is made of thermoplastic resin or a mixture of thermoplastic resin and inorganic loading material. As a result, when the retrieved metallic material and the retrieved insulating material amount to necessities of recycling respectively, both the metallic material and the insulating material are possible for recycling.
