Abstract

PURPOSE:To handle ICs which differ in shape and to reduce the cost by forming holes which are at the same pitch with the ICs and where pins of the ICs are inserted. CONSTITUTION:A pin socket 8 is inserted into many holes 4 of a substrate 1 which is so structured as to supply a voltage to an IC 3 and brought into contact with a source voltage layer 5 capable of applying a source voltage, which is applied to the pin socket 8. The IC pins are inserted into the pin socket 8 to apply the source voltage to the IC 3. When ground is applied, the pin socket 8 is inserted from the side of a ground layer 7. Consequently, the static burn-in board is applicable even to an IC which is different in shape by using the pin socket and the cost is reduced.
