Title:
PRESS-FIT TERMINAL, PRESS-FIT TERMINAL MANUFACTURING METHOD AND STRUCTURE FOR CONNECTING PRESS-FIT TERMINAL AND CIRCUIT BOARD
Document Type and Number:
WIPO Patent Application WO/2006/077827
Kind Code:
A1
Abstract:
A press-fit terminal which prevents a plated surface from being ground even when the terminal is press-fit in a through hole of a circuit board and has a high connection reliability. A method for manufacturing a press-fit terminal to be inserted into the conductive through hole of the circuit board is provided with a base plating step wherein one or a plurality of base plating layers are formed on a terminal base material surface of a press-fit connecting section which is brought into electrical contact with the through hole; an Sn plating step wherein an Sn plating layer is formed on the uppermost base plating layer; and a reflow step wherein heat treatment is performed after forming the Sn plating layer, an alloy layer of Sn and a base plating metal of the uppermost layer is formed on the uppermost base plating layer, and unalloyed Sn is mixed in an uppermost layer of the alloy layer.
