Thermal spring frame and shield for sealed processing systems

A compliant electronics assembly mount frame and package are provided. The compliant frame may include a number of spring features configured to flexibly maintain and/or orient an attached PCBA inside a thermal conduction package. These spring features disposed in the compliant frame may be shaped, sized, and even tuned, to bias heat generating components attached to the PCBA evenly against a thermally controlled surface of the thermal package. The frame may be made or stamped from metal, such as sheet metal, and may be formed to include one or more integral spring features.
