Electronic device package technology is disclosed. In one example, an electronic device includes a substrate having at least one electronic component mounted thereon and a heatsink thermally coupled to the electronic component. A plurality of fasteners attaches the heatsink to the substrate. At least one of the substrate, the heatsink, and the plurality of fasteners include a stress-relieving component to minimize fastener stress on the substrate. The stress-relieving component can comprise a fastener having a compliant device (e.g., a spring) for z-direction stress relief. The stress-relieving component can comprise the substrate and/or the heatsink having an oversized aperture for x-direction and/or y-direction stress relief. A method is disclosed for coupling a substrate to a heatsink. A method is disclosed for minimizing fastener stress locally to fasteners of an electronic device.
