INTEGRALLY BUMPED ELECTRONIC PACKAGE COMPONENTS

摘要

There is disclosed components for electronic packaging applications having integral bumps. A leadframe is formed by etching a metallic strip from one side to form outwardly extending, substantially perpendicular integral bumps. The metallic strip is then etched from the opposite side to form individual leads. When the integrally bumped component is an package base, fatigue of solder balls is reduced.
