Claims

[Scope of utility model registration request]

A probe equipped with a probe that contacts each contact of an IC socket on a burn-in board, an address counter driven by an oscillation circuit, a multiplexer that outputs a predetermined output according to the output of this address counter, and this multiplexer. a line driver that applies the output of the address counter to the connector of the burn-in board; a memory that stores in advance a wiring correspondence pattern between the burn-in board connector and the IC socket and outputs a wiring correspondence pattern according to the output of the address counter; A burn-in board inspection device comprising: a comparison circuit that compares the output obtained by the probe with the output of the memory; and a determination circuit that determines the quality of the burn-in board based on the output of the comparison circuit. .
