Patent ID: 7667976

Claim:
A method of making an electronic circuit device comprising: preparing an electronic element including a housing and at least one lead terminal, the housing having at least one projection projecting therefrom remote from the at least one lead terminal; mounting the electronic element on only a first side of a circuit board in such a manner that the at least one projection is substantially held in point contact with the first side of the circuit board to form a gap between the circuit board and the housing of the electronic element; placing the circuit board in a cavity of a mold in such a manner that a second side of the circuit board is held in close contact with an inner surface of the cavity, the second side being opposite to the first side; and encapsulating the circuit board and the electronic element in a casing by filling the cavity with a resin material so that the gap is filled with the resin material, wherein the second side of the circuit board is exposed to an outer surface of the casing to define part of the outer surface of the casing, wherein the projection projecting from the housing of the electronic element has a substantially conical shape, or, a substantially hemispherical shape, and wherein a vertex of the projection is held in contact with the first side of the circuit board.
