Abstract:
1. A probe card for test of a circuit of an electric device, comprising: a substrate; a plurality of probes provided on the substrate; a plurality of elastic members provided on the substrate, wherein the elastic members are deformed when the probes press the circuit of the electric device, wherein the substrate includes a plate and a plurality of wires provided on the plate, each of the wires being electrically connected to at least one of the probes, each of the elastic members including a plurality of first elastic members on the substrate, each of the first elastic members keeping a first interval from the neighboring probe, thereby each of the first elastic members has deformation toward the neighboring probe with the length of the first deformation being less than the first interval when the first elastic members receive external force; and further comprising a plurality of buffer members, wherein each of the probes has a space therein to receive the buffer members.
