LEAD FRAME AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A lead frame and a method for manufacturing the same are provided to effectively offset bending force for deforming the lead frame by eliminating the opposite side of a raw material through a half etching process. CONSTITUTION: A raw material with a metal plate shape is prepared through a rolling operation. A full etched region is formed by etching the whole thickness of the raw material. A pattern with a half etched region(20e), which is formed by eliminating a part of the raw material in a thickness direction, is formed on the raw material. The other part of the raw material, which is opposite to the side with the half etched region, is eliminated through a half etching process.
