Abstract: Various semiconductor chip packages are disclosed. In one aspect, a semiconductor chip package is provided that includes a package substrate that has a first edge and a second edge opposite to the first edge. A semiconductor chip is mounted on the package substrate. A thermal interface material is positioned on the semiconductor chip. A lid is positioned over the thermal interface material. A spring biasing mechanism is included that is operable to bias the lid away from the package substrate so that the lid, when subjected to a compressive force, can translate toward the package substrate and impart a compressive force on the thermal interface material.

Abstract: A turboshaft or shafted engine, as used in helicopter, aircraft, locomotive, marine engines, and the like, is tested in accordance with a routine maintenance schedule. The turboshaft is drivingly connected to a motor/generator set that also performs the operation of a dynamometer in load testing the turboshaft. The generator operates as a motor to start the turboshaft engine and conduct the diagnostic testing. The output from the turboshaft under test is used as a source of electrical power as a by-product of the diagnostic testing. The mechanical energy produced by the turboshaft is transferred by a power transfer mechanism to the generator. The generator converts the mechanical energy to electricity. As a dynamometer, the generator measures the electricity produced to obtain a measure of the output power of the engine under test.
