Abstract
A power electronic package includes: first and second high thermal conductivity insulating non-planar substrates; and a plurality of electronic components mounted on each of the substrates. The substrates are coupled each other at a plurality of bonding regions so that mechanical separation between the substrates is controlled by the number of the bonding regions, an arrangement of the bonding regions, a shape of each bonding region, and a material of the bonding regions. The mechanical separation provides a net axially-directed compressive force in the electronic components.
