Abstract:
1. A structure for fixing an electronic device having a heat-releasing plate to a substrate, said structure, comprising: a substrate; a land portion which is formed on a front face of the substrate and on which said heat-releasing plate of the electronic device is to be soldered; a through-hole formed in and penetrating said substrate and said land portion, said through-hole being adapted to release heat generated in said electronic device, and said through-hole being formed in one side area of said land portion, said electronic device being disposed such that a specific edge portion of the heat-releasing plate is positioned in an other side area of the land portion; and a partitioning portion provided to be positioned only between the one side area and the other side area of the land portion and between the heat-releasing plate and the land portion, said partitioning portion being adapted for preventing a solder, which should partially run out from the specific edge portion of the heat-releasing plate on soldering the heat-releasing plate to the land portion, from partially flowing into the through-hole.
