<p><P>PROBLEM TO BE SOLVED: To provide a metallic material for connector which has both low insertion force and connection reliability, and to provide a method of manufacturing the same. <P>SOLUTION: The metallic material for connector uses a bar or a square wire rod formed of copper or copper alloy as a matrix and a copper tin alloy layer is formed in stripe shape in longitudinal direction of the metallic material on a part of the surface of the metallic material, and a tin layer or a tin alloy layer is formed on the rest of the surface of the metallic material. Moreover, in the manufacturing method of the metallic material for connector, a bar or a square wire rod of copper or copper alloy is used as a matrix and a tin plated layer or a tin alloy plated layer is formed on this matrix to obtain an intermediate material. Then, reflow processing of stripe shape is carried out in the longitudinal direction of the intermediate material and a copper tin alloy is exposed at a part of the surface. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
