Circuit card assembly

A circuit card assembly comprising in combination

• a generally rectangular configured printed wiring circuit board mounting a plurality of components and having a plurality of apertures formed therein with each aperture having a plurality of contacts formed around a perimeter of the aperture with each contact engaging a corresponding terminal of one of the components positioned over the aperture and with each contact coupled with one of a plurality of electrical conducting paths located on the printed wiring circuit board,
• a connector mounted on one end of the printed wiring circuit board and having connector terminals terminating ones of the electrical conducting paths for interconnecting the terminated electrical conducting paths with plug-in circuit card assembly mounting apparatus,
• a heat sink device mounted on an end of said printed wiring circuit board opposite said connector for dissipating heat generated by ones of the components and which heat sink device is affixed to a pair of metal plates extending outward from the heat sink device with one plate supporting the printed wiring circuit board and mounting heat absorption pedestals each extending upward from a surface of the one plate through a corresponding printed wiring circuit board aperture and engaging the component positioned over the aperture, and
• a plurality of vent tubes positioned between the pair of plates with each vent tube having one end engaging one of the pedestals and an opposite end engaging the heat sink device to conduct heat generated by a pedestal engaged component to the heat sink device.
