Abstract
Abstract A carousel for a probe card assembly which includes opposed planar rings supported and spaced apart by flexible supports. The flexible supports, while supporting the planar rings, also allow the planar rings to rotate with respect to each other. Also included are a plurality of connecting means which pass through perforations in the planar rings so as to thereby make interconnection between a probe card and an interface card in a semiconductor test system.
