Abstract

PURPOSE:To mount or dismount a probe card from above a prober by directing the direction of the projecting face of a terminal pin on the card in the same direction as the probe forming face. CONSTITUTION:When a probe card body 1 is inserted into a through hole formed in a repeating member 7 of a prober, and its collar is clamped with a clamping screw 12 to the member 7. At this time, a socket 6 mounted in the upward attitude on the upper end face of the member 7, and a terminal pin 2 provided at the collar of the body 1 opposed to the upper end face of the member 7 are electrically contacted to be connected by an electric circuit with pogocontact pins 8 formed on the member 7 from the socket 6. The pins 8 are connected through a repeating board 9 to a test head 10.
