Abstract: An electronic package including a first substrate (e.g., printed circuit board), a semiconductor device (e.g., silicon chip), a second circuitized substrate (e.g. polyimide having chrome-copper chrome circuitry thereon) and a heat sink (e.g., extruded aluminum or copper). The heat sink includes pliant members (e.g., pliable leg members) secured thereto or forming part thereof such that the heat sink can be downwardly depressed a predetermined distance to effect contact with the semiconductor device without causing damage thereto. Such downward depression facilitates assembly of the package.
