Abstract
A fixture for assembling a probe card adapted to test integrated circuit patterns having contacts deployed thereon. The card includes an opening providing access to a pattern and a ring of spaced conductive pads surrounding the opening. Anchored on selected pads are blade-like needle-holders having needles extending therefrom to engage the contacts in the pattern being tested. The fixture is designed to facilitate attachment of each needle-holder blade to its pad on the card and to orient the blade before such attachment so that the needle point is precisely aligned with the related contact.
