Abstract: A contact terminal for measurement is provided, for transmitting a signal between a desired probe pin among a plurality of probe pins arranged in parallel at a predetermined distance in a predetermined direction on the surface of a probe substrate and an external measurement apparatus. The contact terminal for measurement includes: a signal terminal having an width smaller than the distance between the probe pins provided on both sides of one probe pin in the arrangement direction; two ground terminals to which a ground potential is applied, which are provided on both sides of the signal terminal in the arrangement direction and which have each width larger than that of the signal terminal in the arrangement direction; and a signal line electrically connecting the signal terminal to a signal input terminal of the external measurement apparatus.

Abstract: A socket electrically coupled to a BGA unit includes a plurality of ball contacts including a housing wherein a through-hole having a larger diameter than that of the ball contact is formed in a surface of the housing, which faces the BGA unit, in order to the through-hole corresponds the plurality of ball contacts and a pin contact provided in a plurality of through-holes and contacting a corresponding side part of the ball contact. More desirably, the plurality of pin contacts is provided in order that each extending directions of the pin contacts are opposite to one another.
