Abstract:
A heat spreader package includes a substrate having a first surface, first traces on the first surface of the substrate, and an electronic component having an inactive surface mounted to the first surface of the substrate. The electronic component further includes an active surface having bond pads. Bond wires electrically connect the bond pads to the first traces. An inverted pyramid heat spreader includes a first heatsink, a first heatsink adhesive directly connecting the first heatsink to the active surface of the electronic component inward of the bond pads, a second heatsink having an absence of active circuitry, and a second heatsink adhesive directly connecting a first surface of the second heatsink to the first heatsink. The second heatsink adhesive is a dielectric directly between the bond wires and the second heatsink that prevents inadvertent shorting between the bond wires and the second heatsink.
