Abstract

A contactor apparatus used in automatic testing in a manufacturing line includes a site for receiving an electrical device with an array of input/output elements on a surface of the electrical device package. The contactor is capable of forming electrical connections with each of the elements in the array. The contactor has a guide plate including plurality of contact elements. Each contact element has a first end and a second end. The contact elements are positioned in an array which corresponds to the array of input/output elements of the electrical device. The guide plate is attached to a printed circuit having a plurality of pads. The pads are also situated in an array. The printed circuit is an interface to test electronics located near the printed circuit. An anisotropic compliant conductive interposer is positioned between the contact elements of the guide plate and pads of the printed circuit. One end of a contact element contacts the anisotropic compliant conductive interposer in response to the other end of the contact element being contacted by the input/output element. The anisotropic compliant conductive interposer conducts electric signals along a path between the one end of the contact element and a pad on the printed circuit below the contact element providing contact force at the contact elements using the input/output elements on the electrical device. The anisotropic compliant conductive interposer has an elastomeric base which counteracts the force from the contact element.
