Patent abstract
Devices such as amplifiers are built on a heat sink having a perimeter wall surrounding active electronic devices. Surprisingly formation of wire bonds to such devices tends to be degraded if they have an aspect ratio greater than 2:1. This problem is overcome by forming wire bonds before such walls have a height of 30 mils and after bond formation extending the walls to their final height.
