Abstract

A contact device having a plurality of nominally coplanar first contact elements makes electrical contact with corresponding nominally coplanar second contact elements of an electronic device when the contact device and the electronic device are positioned so that the plane of the first contact elements is substantially parallel to the plane of the second contact elements and relative displacement of the devices is effected in a direction substantially perpendicular to the plane of the first contact elements and the plane of the second contact elements. The contact device comprises a stiff substrate having a major portion with fingers projecting therefrom in cantilever fashion, each finger having a proximal end at which it is connected to the major portion of the substrate and an opposite distal end and there being one or two contact elements on the distal end of each finger. A mechanical ground is positioned away from the fingers towards the proximal end, and deflection resulting from contact between the probe member and the electronic device is shared between the fingers and a portion of the substrate not including the fingers. Methods utilizing such a contact device also are disclosed.
