A plug-in circuit card assembly for mounting high power electrical and optical components. The apparatus comprises a printed wiring circuit mounting hi gh power electrical and optical components and connectors with conducting paths interconnecting the components and ones of the components with the connectors. The assembly has a structure attached to the printed wiring circuit with a heat sink formed at one end and having a pair of plates extending outward therefrom. One plate mounts a plurality of high thermal conducting pedestals each engaging corresponding ones of the components. Vent tubes are positioned between the plat es with each vent tube having one end engaging one of the pedestals and an opposite end engaging the heat sink and functions to conduct heat from the components to the heat sink for dissipation.
