Abstract:
A test probe contactor includes an angled depressible probe configuration that causes the tips of the compressible probes to “swipe” the contact pads/solder balls of an IC device under test as the contacts are made. The angulation of the depressible probes permit penetration through foreign material layers on the pad/ball surfaces with less contact force. The contactor includes an upper block and a main block for housing the plurality of probes. The main block and the upper block include corresponding pluralities of slanted probe cavities. The upper bore axis of one or more of the upper probe cavities is laterally shifted relative to the main bore axis of a corresponding probe cavity of the main block, resulting in a lateral offset between the upper bore axis and the main bore axis.
