ABSTRACT:
The invention of the present document is an improved disc singulator (10) for use in singulating and delivering to a test site (12) an integrated circuit device (14) to be tested by a tester mechanism. The singulator (10) includes structure to positively hold the device (14) within slots (64) formed in the periphery (52) of the disc (10) as it is rotated. A main body portion (16) of the device (14) is, thereby, held so that a plane defined by the main body (16) is oriented generally orthogonal to a plane defined by the disc (10). Additionally, the device (14) is held at an appropriate radial location with respect to the disc (14) so that, as the disc (10) rotates the device (14) carried thereby through a slit (40) in a printed circuit board (36) at the test site (12), contacts (26) of the device (14) will engage corresponding probes (38) at the test site (12). A wire spring (124) is employed to orient the main body portion (16) of the device (14) within a slot (64) in the disc (10) to prevent canting of the device (14). A plunger (86) and latch (132) are employed to assure proper radial positioning.
