Abstract
A circuit carrier assembly includes a plurality of substrates directly secured together by an electrically conductive securing substance. In one example, the securing substance is a conductive epoxy. In another example, the electrically conductive securing substance is solder. Still another example includes a combination of solder and conductive epoxy. A non-conductive epoxy provides further mechanical connection and thermal conductivity between the substrates while also electrically isolating selected portions of the substrates in one example. The electrically conductive securing substance not only mechanically secures the substrates together and provides thermal conductivity between the substrates, which increases the thermal capacitance of the assembly, but also establishes at least one electrically conductive path between the substrates.
