MANUFACTURING METHOD OF THIN WIRE CONNECTING TOOL

摘要

PROBLEM TO BE SOLVED: To provide a high-precision and low-cost thin wire connecting tool. SOLUTION: The manufacturing method of a low cost thin wire connecting tool equipped with a hollow hole of high precision to insert a thin wire into is provided, in which an inner pipe made by electroforming is made bitten into and integrated with a core pipe for reduction method with a high-precision outer periphery and is cut off to pull out a core wire. With combination of characteristics of both the electroforming method and the pull-stretch method polishing treatment or the like is restrained to a minimum. COPYRIGHT: (C)2003,JPO
