A press-pack semiconductor fixture 200 includes a housing defining an interior passage. A first conductor and a second conductor are mechanically coupled with the housing. The mechanical coupling of the first conductor and the second conductor with the housing is effective to apply a clamping force to a press pack semiconductor. A number of apertures or openings are provided in the housing, the first conductor, and the second conductor to permit fluidic flow 290 between the interior passage 239 and spaces or structures exterior to the housing.
