METHOD FOR MANUFACTURING ELECTRODE TERMINALS FOR ALUMINUM ELECTROLYTIC CAPACITORS AND AN ELECTRODE TERMINAL FOR THE ALUMINUM ELECTROLYTIC CAPACITORS

摘要

Disclosed is a method for manufacturing electrode terminals for aluminum electrolytic capacitors and an electrode terminal for the aluminum electrolytic capacitors wherein whiskers are not produced on the surface of aluminum electrolytic capacitor electrode terminals that are formed by welding untinned lead wires and aluminum round bars. Following an electrode terminal manufacturing process in which an untinned lead wire (12) and a round aluminum bar (14) are welded, and a part of the round aluminum rod is rolled into a flat bar so as to form the round aluminum bar into a flat part (14a) and a round aluminum bar part (14b), and a welding process in which the tips of the electrode terminal lead wires are aligned and welded to a thin semiconductor sheet (20) at a constant interval, a tinning process is performed in which the flat parts of the electrode terminals are grasped by a hanger (30) that is disposed to move on a rail track (40), the electrode terminals are held in a horizontal state, and the hanger is rotated in the vertical direction when it arrives above a tin plating tank (50) to tin a predetermined portion of the electrode terminal lead that does not include the weld (16).
