ABSTRACT:
A space transformer for electrically interconnecting a probe head to a printed circuit board, which includes a flexible multilayer circuit with device under test contact pads formed on a first side and printed circuit board contact pads formed on a second side. Electrically conductive circuit traces extend between the device under test contact pads and the printed circuit board contact pads. A shim plate is fastened to a periphery of the first side of the flexible multilayer circuit and a bottom plate is fastened to a periphery of the second side of the flexible multilayer circuit. The bottom plate has a plurality of internal apertures are aligned with the printed circuit board contact pads separated by bottom plate stanchions that are aligned with the device under test contact pads. A plurality of interconnects are bonded and electrically interconnected to the printed circuit contact pads and extend through the internal apertures.
