Multiple is arrayed the joint terminal which it was jointed by the eye condition of the checker board to the joint surface of the convex spiral condition

摘要

PROBLEM TO BE SOLVED: To provide an connection terminal for an electronic component composed of a convex spiral shape contact in a manufacturing method for producing the terminal while increasing the number of windings, even with fewer processes and for a shorter period of time, and also to provide a connector and a manufacturing method for the connector.;SOLUTION: A convex spiral shape contact 2 to be connected to a plurality of balls 10a arrayed in a grid on a connecting face of a semiconductor device 10 is featured by being formed so as to narrow its width as going on from a root to a tip end in a spiral manner between extremely small gaps in a planar view.;COPYRIGHT: (C)2006,JPO&NCIPI
