US Patent 11330738 Force balanced package mounting

An electronic device is provided that balances the force applied to temperature control elements such that stress within components of the electronic device can be effectively managed. In one example, an electronic device is provided that includes a printed circuit board (PCB), a chip package, a thermal management system, a thermal spreader, and first and second biasing members. The chip package is mounted to the PCB. The thermal management system and spreader are disposed the opposite of the chip package relative to the PCB. The first biasing member is configured to control a first force sandwiching the chip package between the thermal spreader and the PCB. The second biasing member is configured to control a second force applied by the thermal management system against the thermal spreader. The first force can be adjusted separately from the second force so that total forces applied to the chip package and PCB may be effectively balanced.
