ABSTRACT:
An universal connector employing a plurality of double female contacts installed with a certain clearance in receptacles of a body which may be suspended in a coupling position with a plurality of male contacts arranged on the top face of an EWS probe card and with a plurality of male contacts arranged on the bottom surface of a test card in a test-on-wafer station, provides a multicontact universal connection for any pair of so equipped cards of the inventories of probe cards and of test cards of the station. The connection is easily set up and exhibits excellent stability and uniformity characteristics of the electrical couplings, while reducing sensibly the time necessary for the setting-up and debugging of the test station for initiating a certain cycle of testing-on-wafer. The stability and reproducibility of the electrical couplings provided by the connection increases the precision of the measurements of critical parameters of the integrated devices with a positive effect on the production yield.
