Filed: 1992-11-30
Abstract: PURPOSE:To provide the manufacturing method of a resin-molded type electronic part, wherein adhesion between a lead and outer resin is excellent and unnecessary resin flashes can be readily removed. CONSTITUTION:A resin-coat outer part 5, which is the main part of a lead frame 1, is coated with outer resin 6 in the manufacturing process of a resin molded product. During this manufacturing process, the resin-coat outer parts 5 of leads 3a, 3b and 3c of the lead frame 1 are oxidized, and the parts other than the resin-coat outer parts 5 are not oxidized before the resin molding step. Therefore, when the resin-coat outer parts 5 are resin-molded with the outer resin 6 in the resin molded step, the adhesion between the leads 3a, 3b and 3c and the outer resin 6 becomes very excellent at the resin-coat outer parts 5. Thus, the intrusion of moisture through the interface between the leads and the outer resin is prevented. At the parts other than the resin-coat outer parts 5, the adhesion between both parts is poor, and the removal of the unnecessary flashes attached to the leads 3a, 3b and 3c becomes easy.
