ABSTRACT:
A unitary strip of thermally and electrically conductive spring material is formed with two rows of spring fingers formed at one end which have frictionally engaged therebetween the bus bar or plate of a solid-state device such as an FET having leads soldered to a printed circuit board. The opposite end of the strip is fastened mechanically to a conductive heat sink block on the circuit board. The strip provides electrical power, support for, and heat sinking of the solid-state device.
