Patent ID: 7063542

Claim:
A compliant electrical probe device for conducting electrical signals from an electronic package on one side of the compliant electrical probe device to an electrical member on the other side of the compliant electrical probe device, the compliant electrical probe device comprising: an anisotropic conductive elastomer (ACE) material-based layer defining two opposing faces and comprising a series of conductive pathways extending between the faces; and at least two flexible circuit elements, each flexible circuit element defining two opposing faces with a flexible insulating layer between the faces, an inner face of one of the flexible circuit elements comprising spaced conductive pads in electrical and physical contact with one face of the ACE-based layer, and an inner face of another flexible circuit element comprising spaced conductive pads in electrical and physical contact with the other face of the ACE-based layer, the outer faces of each of the flexible circuit elements carrying electrically-conductive pads that define the contacts for the electronic package and the electrical member, the flexible circuit elements each further comprising conductive pathways interconnecting opposing pads on its faces; wherein the ACE-based layer and flexible circuit elements together accomplish a compliant electrical probe device.
