Abstract

PURPOSE: To attain an excellent lock effect of a molding resin so as to obtain a lead frame prevented from separation of the molding resin by a method wherein an edge 3 of a mounting section and a lead section of the lead frame is so formed as to have a profile with a inclined area facing toward a front side of the lead frame.
CONSTITUTION: An edge 3 of a mounting section 1 and a lead section 2 of a lead frame is so formed as to have a profile with a inclined area 4 facing toward a front side of the lead frame. To form the lead frame mentioned above, for instance, attachment such as oil, contaminant, or the like on the surface of a metallic plate 0.27 mm thick formed of 42 alloy is removed by the use of degreasing solution, and negative-type sensitizing solution is applied onto the both sides of the said metallic plate, which is dried through heating and thereafter is subjected to exposure to light with applying a front pattern 11 and a rear pattern 12 to the both sides. Next, development is performed using warm water for the formation of a resist pattern, and then corrosive solution is sprayed with a nozzle upon the both sides of the said metallic plate and the unneeded part is removed through etching so as to form a lead frame. And, resist is removed using resist stripping agent and then plating is performed thereon.
