Abstract:
1. A method for manufacturing a probe card, comprising: preparing a plurality of probes, each probe having a probe tip portion and a columnar attaching portion, the columnar attaching portion having a circumferential surface; forming, for each of the plurality of probes at a part of the circumferential surface, a metal layer having higher wettability than that of the attaching portion; forming, for each of the plurality of probes, a layer of a hot-melt material to cover the metal layer and at least a part of the circumferential surface exposed from the metal layer; preparing a probe substrate having a plurality of through holes penetrating in its thickness direction; for each of the plurality of probes, inserting its attaching portion into a different one of the plurality of through holes of the probe substrate so that at least a part of its metal layer is located in the through hole in which the attaching portion is inserted; melting the hot-melt material of each attaching portion; and thereafter solidifying the hot-melt material in a state where the hot-melt material contacts the part of the metal layer and a part of a wall surface of the through hole to fix each probe to the probe substrate.
