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