Patent abstract
Proposed is a method for separating dross in a soldering process for a printed circuit board using a tin bath containing liquid tin. The method includes collecting dross produced during the soldering process; grinding the dross to tin ash in the tin bath for allowing a portion of tin contained in the tin ash to be melted again to join the liquid tin; and scooping up and recycling the tin ash not melted in the tin liquid. The method precludes a waste of tin resources and high manufacturing costs which might otherwise arise from directly scooping up dross of high tin content.
