ABSTRACT:
A method of forming a high fin density heatsink from a plurality of fins each having a bottom portion of generally bell-bottom shape and a base unit of predetermined thickness having a plurality of grooves therein. The method comprises the steps of placing the plurality of fins loosely in respective ones of the grooves, and applying downward and horizontal pressure to the base unit intermediate respective ones of the fins for swaging the base unit so as to urge the fins downwardly into the respective ones of the grooves thereby creating a solid connection between the base unit and the fins with excellent thermal contact therebetween.
