ABSTRACT:
In an electric circuit assembly (2) having conductive lead frames (8-10) directly bonded to an insulating substrate (6) by a eutectic, the lead frames are further subjected to a work hardening step (32, 34) to stiffen the lead frames and enable push-on fastener connection (12) to the lead frames without collapse thereof.
