The invention relates to an apparatus for testing an integrated circuit of an electronic device.

Integrated feedthrough module

Separate test electronics and blower modules in an apparatus for testing an integrated circuit

A high density interconnect system (30) employs contact fingers (32) on both surfaces (34) and (36) of burn-in PCB (38), feed-through PCB (40) and driver PCB (42). Each of the PCBs (38), (40) and (42) has a card-edge connector (44), (46) and (48). The feed-through PCB (40) has a second card-edge connector (40) and a second set of contact fingers (32), since it mates with both the burn-in PCB (38) and the driver PCB (42). The contact fingers (32) and the card-edge connectors (44), (46), (48) and (50) of each PCB (38), (40) and (42) mate inversely with each other on adjacent PCBs, i.e., the card-edge connector (44) of the burn-in PCB (38) mates with the contact fingers (32) of the feed-through PCB (40), and the card-edge connector (46) of the feed-through PCB (40) mates with the contact fingers (32) of the burn-in PCB (38), for example. The same relationship exists between the card-edge connector (50) of the feed-through PCB (40), the card-edge connector (48) of the driver PCB (42) and the contact fingers (32) of the feed-through PCB(40) and the driver PCB (42).
