Publication number: 20200348359Abstract: The invention relates to a test needle for measuring electrically conductive layers in holes of printed circuit boards, as well as to a test probe equipped with such a test needle and to a flying probe tester for testing printed circuit boards equipped with such a test needle or such a test probe. The test needle has a capacitive measuring body, which is connected via a cable to a capacitive measuring device. The cable is shielded so that only the capacitive measuring body can form a capacitive coupling with other electrically conductive bodies. This makes it possible to determine this capacitive coupling with a high local resolution.Type: ApplicationFiled: January 17, 2019Publication date: November 5, 2020Applicant: Xcerra CorporationInventors: Stefan Weiss, Oleh Yuschuk, Christian Weindel

Patent number: 10101360Abstract: A test socket with a link and mount system is used to couple a device under test to a testing apparatus for quick and reliable testing of microchips post-production. The socket includes a pivoting link that connects to the DUT, an elastomer for biasing the link in a first preferred orientation, and a mount that operates as a fulcrum to rotate the link into engagement with the DUT. The mount includes projections that extend below a bottom surface of the socket, such that engagement of the mount with the test device at the projections translates the mount parallel to a diagonal support wall in the socket such that the mount is driven away from the bottom surface of the socket and also toward the elastomer. The socket includes a gap above the mount to allow for movement of the mount within the socket, eliminating the fixed arrangement and the non-compliant loads that accompany the engagement of the mount to the test apparatus.Type: GrantFiled: November 2, 2016Date of Patent: October 16, 2018Assignee: Xcerra CorporationInventors: Aaron Magnuson, Sergey Yakushev, Valts Treibergs, Dan Sikorski
