Abstract
A method and apparatus for aligning two mating tools is provided by a plurality of alignment members extending upward from the surface of one mating tool so that the alignment members engage in slidable contact with alignment tracks formed in the edges of the second mating tool. The alignment members and tracks can be formed in the four corners of rectangular mating tools, and the alignment members can be cylindrical rods with dome shaped tops. The alignment is useful both for tooling set-up as well as tooling usage. The alignment means can be used on a punch and lead form anvil for forming the outer leads of an integrated circuit bonded to a TAB tape.
