ABSTRACT:
A method is described for coupling the leadframe of a thermogenetic semiconductor device to a heatsink. This method consists of screening a first layer of thermally conductive epoxy on the heatsink. The first layer is cured and a second layer is screened on the first layer. The leadframe is then deposited on the second layer and the second layer is cured. The device then goes to encapsulation and final processing.
