Abstract

See full text

A tool having a coining projection is operative for forming a frangible portion in a lead of a microelectronic connection component by application of a compressive force. The coining projection is supported on a pedestal formed from a tool body. In an alternative embodiment, the pedestal is formed on a backing plate for use in circuits up construction. The pedestal is sized and shaped so as to be received within a gap formed in a support layer for the leads. By application of the compressive force, the coining projection will penetrate the lead within the region of the gap to form the frangible portion.
