Abstract
Terminals (2, 502) of a device under test (DUT) are connected to corresponding contact pads or leads by a series of electrically conductive contacts. Each terminal testing connects with both a “force” contact and a “sense” contact. In one embodiment, the sense contact (770) partially or completely laterally surrounds the force contact (700). In order to increase the contact surface, the force contact, in a spring pin (700) configuration contacts the device under test terminal at that portion of the lead which is curved or angled, rather than orthogonal to the pin.
