Abstract:
An elongate electrical contact element (1) for physically contacting electrical components under test, having two electrical contacting end regions (2, 3) and an elongate intermediate region (4) situated between the end regions (2, 3). The intermediate region (4) has an essentially rectangular cross-section and is configured lamellar along its longitudinal extent. Also disclosed is a corresponding contacting apparatus (22) including such a contact element (1) and a contact element holder (23).
Abstract:
A contacting device for touch contacting an electrical test specimen includes a contact head and a connecting device. The contact head with the test specimen have electrically touch contactable test contacts, the positions of which are distributed across a testing surface and are determined by at least one guide element that belongs to the contact head and that is fastened to a holding device of the contact head. The test contacts, on their side facing away from the test specimen, are to be brought into electrical touch contact with contact surfaces of the connecting device. It is provided that the guide element is composed of individual segments that each have a part of the testing surface and are each connected to at least one of the holding device and the connecting device by at least one fixed bearing.
Abstract:
The present disclosure relates to a test head for electrical testing of a test specimen, in particular a wafer, having at least two guide plates, which are spaced apart by means of at least one spacer and have guide holes distributed over the surfaces thereof, in which test contact pins for physical contact with the test specimen are guided in a sliding manner. Provision is made for the spacer to be formed by a multiplicity of point supports arranged in a manner distributed over the surfaces of the guide plates and secured on the guide plates.

Abstract:
A contact-making apparatus for electrical connection of a unit under test to an electrical test device. The apparatus has a plurality of electrical test contacts, which are associated with at least one holding element, for making contact with the unit under test. An adapter device increases the distance between adjacent contact paths. The adapter device has contact elements for touch contact with the test contacts. The contact elements are comprised of noble metal or of a noble metal alloy, or of an alloy having at least one noble metal component, or of electrically conductive plastic. The invention also relates to a corresponding method of forming the contact elements by heating and then cooling and then forming the apparatus.
