US Patent 7447035 Heat dissipation device assembly

A heat dissipation device assembly is mounted on a printed circuit board (80). First and second electronic components (82, 84) are mounted on the printed circuit board. The heat dissipation device assembly includes a first heat sink (10) in thermal contact with the first electronic component, and a second heat sink (20) in thermal contact with the second electronic component. A spring tab (24) is sandwiched between the first and second heat sinks for providing spring force between the first and second heat sinks thus securely mounting the second heat sink on the second electronic component.
