ABSTRACT:
In an adapter card, is a clock signal converting circuit converts a clock signal, output from a signal generator of a burn-in apparatus, from a lower—to a higher-frequency clock signal. Plural delay circuits synchronize each burn-in signal output from the signal generator with the clock signal. A connector of an adapter is connected between a burn-in card and a connector mounted in a burn-in chamber, to burn in a semiconductor device mounted on the burn-in card. The output of the signal generator is fed into the adapter card via its connector, and the output of the adapter card is supplied to the semiconductor device mounted on the burn-in card to burn in the semiconductor device.
