Patent ID: 8312626

Claim:
A manufacturing method for a probe contact, comprising the steps of; arranging, on a front face of a substrate, a plurality of leads in parallel for tips thereof to be positioned on a sacrifice layer formed on a part of the front face, forming into a rear face a carved groove passing just under the sacrifice layer, fracturing the substrate along the carved groove and cutting off a removing part thereof after the sacrifice layer is removed, and projecting the tips of the leads from an end portion of a remaining substrate; forming a fracture controlling structure of a metallic or insulating material on the front face of the substrate to give locally the front face of the substrate a stress at a position pinching the plurality of leads from both sides thereof on the front face of the substrate, and controlling a position of fracturing on the substrate by the fracture controlling structure, and pushing the removing part from the side of the front face to fracture the substrate, wherein the fracturing does not break the fracture controlling structure.
