Title:
VERTICAL CONTACT-TYPE PROBE, PROBE CARD, AND SOCKET
Document Type and Number:
WIPO Patent Application WO/2021/235483
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a vertical contact-type probe, a probe card, and a socket that have excellent durability for the inspection of a DUT, i.e., a semiconductor IC or a packaged semiconductor, having a small electrode interval, and that can handle high-frequency inspection of DUTs having high operation frequency. Provided is a vertical contact-type probe (1) which, in a state in which: a first needle-like electrically conductive member (20) extends in a thickness direction of an elastomer sheet (12) on a first surface (10a) side of an elastomer connector (10); a first end (20a) of the first needle-like electrically conductive member (20) is in contact with a metal thin wire (14); a second needle-like electrically conductive member (30) extends in a thickness direction of the elastomer sheet (12) on a second surface (10b) side of the elastomer connector (10); a first end (30a) of the second needle-like electrically conductive member (30) is in contact with the metal thin wire (14); and a second end (30b) of the second needle-like electrically conductive member (30) is in contact with an electrode terminal of a circuit board, inspects a DUT by causing a second end (20b) of the first needle-like electrically conductive member (20) to contact an electrode of the DUT.
