Claim of US Patent No. 10,512,168

1. An electronic device comprising:a printed circuit board having a first main surface;
an electronic part mounted on the first main surface; and
a first connection member connecting the printed circuit board and the electronic part,
the printed circuit board including at least one projection formed on the first main surface so as to project in a direction crossing the first main surface,
the at least one projection being formed outside a bottom surface of the electronic part located at a side of the first main surface,
the first connection member being in contact with at least part of the at least one projection, at least part of the bottom surface of the electronic part, and at least part of a lateral surface of the electronic part intersecting the bottom surface,
the first connection member is formed so as to entirely cover at least a top surface of the at least one projection,
the printed circuit board includes a wiring pattern formed on the first main surface,
the at least one projection is formed on a region of the first main surface in which the wiring pattern is not formed,
the at least one projection is formed at a spacing from a perimeter of the bottom surface, and
the spacing is greater than or equal to a height of the at least one projection in a direction perpendicular to the first main surface and is smaller than or equal to a width of the at least one projection in a direction extending along the first main surface and extending from the electronic part toward the at least one projection.
