This invention solves the problem of probing and debugging logic cards by allowing the cards to function outside their cage. The card extender connects to the pins of a related ZIF (Zero Insertion Force) connector supplying proper interconnection, cooling, and support for the card being probed. It also uses very short signal lines keeping signal delay to a minimum. The lower support 1 is a plastic frame and holds the lower ZIF connector 4, which snaps under four plastic retainers, and also a 3-1/8-inch cooling fan 3. The upper support 2, also a plastic frame, holds the upper ZIF connector 7 under four plastic retainers and snaps over the lower support 1, to complete the assembly. The card 6 to be probed is inverted and inserted in the two ZIF connectors 4 and 7.
