Abstract

The electrical contact assembly is suitable for formation of either tangential wiping and proving contactors for test points 4 on a semi-conductor chip 5. The contact assembly is fabricated from a conductive spring metal wire which is spirally wound, as in A, into a coil 1 with accurate spacing between the convolutions. A longitudinal portion 8 of coil 1 is embedded, as in B, in potting material 2. By longitudinally severing the coil, each convolution is isolated from adjacent ones to thus form a plurality of individual contacts 3 of the multicontact assembly 6 as in C.
