ABSTRACT:
An automatic soldering apparatus and method includes compressed air pipes on both sides of a ceramic foaming tube to prevent through holes of the ceramic foaming tube from being clogged by a foreign substance and to constantly maintain the air pressure within the ceramic foaming tube for uniform dimension of foaming flux and uniform foaming height, thereby performing uniform flux treatment upon a circuit board to eliminate inferiority caused by the foaming flux.
