Sensing probe for determining location of conductive features

摘要

A sensing apparatus for determining the precise location of a conductive feature on an insulating substrate which has a base, a plurality of flexible flat elongated contact blade elements having end portions for contacting and establishing electrical contact to a conductive surface feature, insulating means between the blade elements, and a base member for supporting the blade elements in a bowed condition with the end portions arranged in a plane parallel to the plane of the top surface of the insulating substrate.
