Abstract
A burn-in board Vcc circuit changeover socket 204A and a GND circuit changeover socket 205A wich are arranged in a wiring area between terminals 1 to 7 of an IC socket 202 and resistors 203 corresponding to these terminals. A Vcc circuit changeover socket 204B and a GND circuit changeover socket 205B are arranged in a wiring area between terminals 8 to 14 of the IC socket 202 and resistors 203 corresponding to these terminals. A Vcc circuit changeover unit 206 is fitted, for example, in the Vcc circuit changeover socket 204A and a GND circuit changeover unit 207 is fitted, for example, in the GND circuit changeover socket 205B. A first electric potential (Vcc) is supplied to the terminals 5 and 7 of the IC socket 202, and a second electric potential (GND) is supplied to the terminals 12 and 14 of the IC socket 202. The Vcc circuit changeover unit 206 and the GND circuit changeover unit 207 may have different plug-in terminals according to kinds of ICs which may be made.
