Patent ID: 8493086

Claim:
An electrical signal connector comprising: a resin-made film probe including: a resin film with metal foil adhering thereto; an elastically deformable probe part formed by etching the metal foil to form a conductive pattern on the resin film, a signal input end part formed by one end of the elastically deformable probe part and protruding from one side of the resin film; and, a signal output end part formed by another end of the elastically deformable probe part and protruding from an opposite side of the resin film; and the connector further comprising: a probe unit in which a plurality of resin-made film probes, corresponding to one or more pads on a semiconductor chip to be tested, are supported in parallel on a plurality of support plates; a first probe holder of grid structure provided with a plurality of openings; and a second probe holder of the same configuration as that of the first probe holder, the second probe holder having projections at intersection points in the grid structure, wherein the first and second probe holders are fastened to the circuit board with the projections of the second probe holder inserted in corresponding holes of the circuit board and the first probe holder being fastened to the circuit board with screws; and wherein each of the probe units is separately disposed in and fixed to each of the openings and a circuit board is sandwiched between the first probe holder and the second probe holder.
