Some circuit modules have a flat chip carrier, an array of chips mounted on an upper surface of the chip carrier, and an overlying supporting structure called a hat that is water cooled. Cylindrical metal pistons contact the upper surface of a chip for conducting heat to the hat. A piston is slidably mounted in a hole in the hat and is spring loaded so that it can adjust to the vertical position and the orientation of the chip.
