Publication number: 20150072165Abstract: A bonding member that includes a plating film containing a Cu—Ni alloy as its main constituent. In this plating film, the Cu mass ratio Cu/(Cu+Ni) is increased and decreased between 0.7 and 0.97 in the film thickness direction. In addition, the amplitude between the increase and decrease in the Cu mass ratio is larger than 0.1. Therefore, when the plating film containing the Cu—Ni alloy as its main constituent and Sn-based solder material or the like are joined by soldering, an intermetallic compound layer with a high melting point is formed. In addition, the plating film has a layer with a slow reaction rate, and thus can slow the reaction rate of alloying reaction between the Cu—Ni alloy and a Sn-based metal.Type: ApplicationFiled: November 19, 2014Publication date: March 12, 2015Inventors: Tomohiro Sunaga, Daisuke Megumi, Yoshihiko Takano, Hidekiyo Takaoka
