ABSTRACT:
A mounting entity comprises, in layered order, a pressure sensitive adhesive, a foam spacer, a second pressure sensitive adhesive, a filler, and a heat sensitive adhesive. The first pressure sensitive adhesive is attached to an electrical component which is then mounted upon a printed circuit with the heat sensitive adhesive in contact therewith. The passing of the board over a solder wave heats the top surface of the board to a temperature high enough to activate the heat sensitive adhesive and adhere the component to the board. The intermediate foam layer dampens shock and vibration.
