ABSTRACT:
The present invention provides a recycler that recycles 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. The insulating body base of the printed circuit board as the waste printed circuit board can be a thermoplastic resin or a mixture of thermoplastic resin and inorganic loading material. The recycler includes a pressuring device that pressurizes the waste printed circuit board, a heater that heats the waste printed circuit board to a predetermined temperature at which the waste printed circuit board is at least softened, and a filter that filters the resin material from the waste printed circuit board. The heater can be maintain the filter at the predetermined temperature provided by the heater.
