Abstract:
1. A probe card assembly comprising: a wiring substrate comprising an electrical interface to a tester for controlling testing of an electronic device to be tested; and a probe substrate comprising a plurality of probes disposed in a pattern that corresponds to terminals of the electronic device to be tested, each of the probes comprising a carbon nanotube column comprising a bundle of carbon nanotubes; adhesive material joints one of the carbon nanotube columns to one of a plurality of terminals of the probe substrate, each of the adhesive material joints comprising a mass of sintered nanoparticles fused to the one of the carbon nanotube columns and the one of the terminals, wherein the probe substrate is mechanically coupled to the wiring substrate and the probes are electrically connected through the probe substrate and the wiring substrate to the electrical interface.
