METHOD FOR INNER LEAD MANUFACTURING IN FINE PITCH LEADFRAME

摘要

A method of fabricating the inner leads of a fine pitch leadframe having a small interval between leads. The inner leads of the fine pitch leadframe are fabricated by combining a new stamping tool for fabricating extended fine pitch portions of inner leads with an existing stamping tool for fabricating the inner leads of a leadframe. This method obviates the time and expense of manufacturing an entirely new stamping tool.
