ABSTRACT:
A heat exchange attachment device for integrated circuits is presented which eliminates any need for contact with adhesive pastes or solder. A snap-on holding piece permits a finned cooling unit to be threaded through an aluminum base plate attached to the pin grid array package so that a threaded shaft of the cooling unit may be screwed into adjustable contact with a beryllium oxide disk mounted on the integrated circuit package.
