ABSTRACT:
An electronic device is mounted on a wiring board, which includes: a substrate having through holes, and lands extending on surfaces of the substrate and adjacent to openings of the through holes. Further, at least one coating layer is provided, which coats at least one part of an outer peripheral region of the at least one land, in order to cause that the at least one part is separated from a lead-less solder, thereby preventing any peel of the land from the surface of the substrate.
