Patent ID: 7456640

Claim:
A structure for electrically coupling probes of a probe device to corresponding electrical contacts on a product substrate, the structure comprising: a thin film of electrically insulating material having a plurality of apertures formed therein, wherein the thin film of electrically insulating material is releasably coupled with the product substrate; an electrically conductive material in the apertures; a first plurality of electrical contacts disposed on a first surface of the thin film of electrically insulating material, wherein the first plurality of electrical contacts are configured to be electrically connectable with the electrical contacts on the product substrate; and a second plurality of electrical contacts disposed on the second surface of the thin film of electrically insulating material, wherein the second plurality of electrical contacts are arranged in a pattern corresponding to the electrical contact footprint of the probe device, wherein the first plurality of electrical contacts on the first surface of the thin film of electrically insulating material are connected to the second plurality of electrical contacts on the second surface of the thin film of electrically insulating material via the electrically conductive material in the apertures, and the apertures include a first aperture and a second aperture, the first aperture including a first end on the first surface and a second end on the second surface and the second aperture including a first end on the first surface and a second end on the second surface, a distance between the first end of the first aperture and the first end of the second aperture is substantially the same as a distance between the second end of the first aperture and the second end of the second aperture.
