Abstract

PURPOSE:To simply remove a resin burr projected at the root of a lead led externally from a resin block by spraying high temperature steam to the burr. CONSTITUTION:A resin burr 4 is produced at the root of each lead 3 of a lead frame 2 projected from the side face of a sealing resin block 1, and high temperature steam being higher than 190 deg.C is sprayed from a nozzle 5 toward the burr 4, thereby embrittling and spraying out the burr 4. In this manner, the burr can be readily removed without damaging the lead 3 and the block 1.
