Abstract:
Systems and methods are provided for producing an integrated circuit package, e.g., an SOIC package, having reduced or eliminated lead delamination caused by epoxy outgassing resulting from the die attach process in which an integrated circuit die is attached to a lead frame by an epoxy. The epoxy outgassing may be reduced by heating the epoxy during or otherwise in association with the die attach process, e.g. using a heating device provided at the die attach unit. Heating the epoxy may achieve additional cross-linking in the epoxy reaction, which may thereby reduce outgassing from the epoxy, which may in turn reduce or eliminate subsequent lead delamination. A heating device located at or near the die attach site may be used to heat the epoxy to a temperature of 55° C.±5° C. during or otherwise in association with the die attach process.

Claim (Index 8):
A system for manufacturing an integrated circuit device, the system comprising:\n a loading unit configured to position a lead frame on a machine feeder, the lead frame including a die support area and a plurality of leads; the machine feeder configured to deliver the lead frame to an epoxy dispensing unit and to a die attach unit; wherein the epoxy dispensing unit is configured to deposit epoxy on at least a portion of the die support area of the lead frame; wherein the die attach unit includes:\n a mounting unit configured to mount the integrated circuit chip over the epoxy-covered die support area; and \n a die attach heating unit configured to apply heat to at least the epoxy to achieve additional cross-linking in the epoxy reaction and reduce outgassing from the epoxy.
