An electrical assembly which includes a clip that couples a thermal element to an integrated circuit package. The integrated circuit package is mounted to a printed circuit board. An elastomer is located between the printed circuit board and the clip. The assembly is designed so that the elastomer applies a pre-load force which pulls the thermal element into the integrated circuit package. The pre-load is typically set so that the thermal element does not become separated from the package when the assembly is subjected to external shock and vibration loads. The elastomer applies the pre-load force uniformly along the area of contact with the printed circuit board. The elastomer does not create localized high stress points on the board. Additionally, the elastomer has an inner opening that is larger than the outer dimensions of the integrated circuit package so that the elastomer applies the pre-load force onto the board in an area away from the solder joints of the package.
