Zusammenfassung:A flexible probe card according to the present invention includes a compression layer; a transport layer coupled to the compression layer; and a contact layer coupled to the transport layer. The compression layer is formed of encapsulated closed cell polyurethane foam. The transport layer includes connectors for coupling the flexible probe card to a tester. The contact interface layer includes embedded conductive wires placed in a fixed grid pattern in a silicon rubber layer without a specific connector pattern associated either with the transport layer or a device under test.
