PARTIAL PLATING METHOD AND PRESSER JIG USED THEREFOR

摘要

PURPOSE:To propose a partial plating method which prevents harmful plating deposited on the side of a lead frame capable of prevent the effects induced by the shape of the lead frame and a presser jig adopted for the above method in terms of a process which consumes expensive Au and Ag and die-bonding process and wire-bonding process. CONSTITUTION:This invention covers a partial plating method and a presser jig adopted for the plating method where the surface of a metal plate 4 having the same shape to that of a minimum plating area for a lead frame 1 is cover with an insulator 5 between elastic body 2 on the rear side and a plating mask 3 on the front side so as to produce a presser jig 6 and the plating is interposed and aligned with the lead frame 1 on the front side of the insulation 5 of the presser jig.
