Abstract
A METHOD FOR MANUFACTURING A LEAD FRAME INCLUDING THE STEPS OF ELECTROCLEANING THE SURFACE OF A THIN PLATE MATERIAL, ELECTROPOLISHING THE ELECTROCLEANED THIN PLATE MATERIAL, REMOVING INCLUSIONS ON THE SURFACE OF THE ELETROPOLISHED THIN PLATE MATERIAL, RINSING THE INCLUSION-REMOVED THIN PLATE MATERIAL WITH AN ACIDIC SOLUTION, AND FORMING MULTI-PLATED LAYER ON THE RINSE MATERIAL. THE LEAD FRAME MANUFACTURED BY THE METHOD HAS 5 OR LESS INCLUSION EACH HAVING APPROXIMATELY 1 ( )M, ON THE SURFACE AREA OF 1600 ( )M2, WHICH INPEDE A WIRE ONDING P[ROPERTY OR SOLDER WETTABILITY ON THE LEAD FRAME.
