1. A method for constructing a probe tip assembly comprising the steps of:
- (a) providing a substantially rigid support;
(b) securing a plurality of independently flexible contact fingers to said support, each contact finger spaced apart from the other ones of said plurality of contact fingers and extending from a first end portion proximate the securing point to said support and terminating in free space at a second end portion distal from said support;
wherein said contact fingers are arranged in a predetermined alignment to spatially align said second end portions with electrical contacts on a circuit board and, to spatially align said first end portions with contact pads of an electrical device to be probed;
(c) attaching said second end portions to said electrical contacts; and
(d) removing said support leaving said first end portions terminating in free space and spatially aligned for engagement with said contact pads.

Abstract
The present invention relates to a probe tip assembly for testing of integrated circuits or other microelectronic devices. The probe tip assembly may include a plurality of independently flexible contact fingers extending from a support, each contact finger spaced apart from the other contact fingers, and each contact finger terminating in free space at an end distal from the support. A probe may be constructed by attaching the free ends of the contact fingers to electrical contacts on a circuit board and then removing the support from the contact fingers.
