Patent ID: 8851358

Claim:
A method for manufacturing an electrical connecting apparatus, comprising: preparing a connection base plate having a surface provided with a plurality of connection pads to which probes are to be connected, and a plurality of land portions having metal surfaces; preparing a plurality of probes having connection end portions configured for connection to the connection pads; preparing a holding plate made of a non-metallic material in which probe through holes are adapted to hold the respective connection end portions of the probes opposed to the corresponding connection pads, and the holding plate having land through holes provided therein and formed in a plate thickness direction, wherein the land through holes correspond to the land portions, wherein the land through holes have open ends opened to the corresponding land portions, and wherein the land portions are sized to fit within the respective open ends of the land through holes; approximating opposed surfaces of the connection base plate and the holding plate to each other to relatively align the plates with each other so that the respective probe through holes may be opposed to the corresponding connection pads of the connection base plate, so that the respective land through holes may be opposed to the corresponding land portions of the connection base plate, and so that the land portions may close the at least parts of the open ends of the respective corresponding land through holes; arranging solder materials on the land portions in the land through holes; thermally melting the solder materials in the land through holes on the land portions in a state in which alignment between the connection base plate and the holding plate is held to form guide portions extending along circumferential surfaces of the land through holes in the corresponding land through holes from the land portions by solidification of the solder materials; separating the connection base plate and the holding plate so that the guide portions may be escaped from the land through holes; arranging the plurality of probes appropriately in the respective probe through holes of the separated holding plate, and by making the guide portions of the connection base plate fitted in the land through holes of the holding plate in a state in which the connection end portions of the respective probes arranged in the holding plate are opposed to the corresponding connection pads, aligning the connection base plate and the holding plate with each other so that the respective connection end portions of the probes may correspond to the respective corresponding connection pads of the connection base plate; and fixing the connection end portions of the probes to the respective corresponding connection pads of the connection base plate in a state in which the holding plate and the connection base plate are relatively aligned.
