Abstract
A substrate is made of resin or a composite material. Pins with Au plating on their surface are soldered, with a soldering material made of Sn and Sb, to a substrate body having a first main surface, and formed into substantially a rectangular shape to project over the first main surface of the substrate body. Wettability of the soldering material for securing the pins and the substrate body is relatively low as compared with that of a Pb—Sn soldering material. Therefore, the height of upward movement of the soldering material along the pin can be reduced. Thus, the pins can be deeply inserted into socket so that the gap between the first main surface of the substrate body and the upper surface of the socket is reduced. As a result, the overall height realized the substrate made of resin has been joined to the socket can be reduced.
