Abstract
A burn-in board construction mounts and provides operational signals to circuit packages, for example, digital devices in an environmental stress operation such as in an oven/chamber for dynamic burn-in. Each of the circuit packages has connections to circuits and which connections are connected to conductors on the burn-in board. At least one auxiliary board is mounted on a main burn-in board and carries contacts to double the number of test connections for digital devices on such burn-in board without changing the basic mounting or environmental chamber construction. The construction permits two 128 pin driver/receiver boards of standard design to be connected to each burn-in board module. This permits coupling several hundred driver connections to a single burn-in board while still utilizing standard connectors as the interconnects.
