The excise and lead form of TAB leads bonded to an integrated circuit chip. Leads extending beyond a sidewall are clamped between a first clamp and a form anvil at a first portion spaced from the chip. The leads are also clamped between an excise/form tool and a second clamp at a second portion spaced further from the chip than the first portion. An excise blade cuts the leads outside the second portion. Then the excise/form tool, second clamp and excise blade move downwards in a curved path toward the chip to form a first lead corner against the form anvil and a second lead corner against the excise/form tool without splaying or galling the leads.

Method and apparatus for the excise and lead form of TAB devices

A plating rack for use in electroplating at least one substrate includes a rack body onto which the substrate may be placed; a metal ring connected to the rack body so as to surround a substrate placed on the rack body; and bistable, single-tipped cam assemblies for holding a placed substrate in place and for making electrical contact between the metal ring and the substrate.

A plating rack for use in electroplating at least one substrate includes a rack body onto which the subtrate may be placed; a metal ring connected to the rack body so as to surround a substrate placed on the rack body; and bistable, single-tipped cam assemblies for holding a placed substrate in place and for making electrical contact between the metal ring and the substrate.

Plating rack

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.
