摘要: There is disclosed herein an electronic component 10 having an integral heat spreader 16 specially designed to assist in laser soldering of the heat spreader to a solder pad 22 on a substrate 20. The component 10 has a top surface 30, a bottom surface 32 generally parallel to the top surface, and at least one perimeter outer surface 34 generally orthogonal to and between the top and bottom surfaces. The component 10 comprises: a circuit portion 12; at least one termination 14 connected to the circuit portion 12 and extending outward therefrom; a heat spreader 16 portion situated generally beneath and in thermal contact with the circuit portion 12; and a body portion 18 enclosing at least a top surface of the circuit portion 12 and a part of each termination 14 proximate the circuit portion 12. The heat spreader 16 defines at least part of the bottom surface 32 of the electronic component 10 and at least part of the at least one perimeter outer surface 34 of the electronic component 10.
