A circuit board holds several circuit cards and circuit modules and other components are mounted on opposite sides of each card so that the tops of modules of one card face the tops of modules of the next card. The cards are spaced apart sufficiently to permit a water-cooled cold plate to be located in the space between cards, and the cold plates are interconnected at the ends of the cards to form a serpentine path for a liquid coolant. The tops of the modules carry leaf springs that engage the cold plate when the card is inserted into a socket on the board.
