    摘要: An electronic device package with enhanced heat dissipation effect comprises a lead frame and an outer frame with electrically insulating surface. The outer frame encloses the electronic device with a predetermined gap therebetween. The lead frame has a plurality of inner leads extending to the upper surface of the electronic device and a plurality of outer leads enclosing the outer surface of the outer frame. Each inner lead and each outer lead are linked by a slanting portion. The plurality of outer leads includes at least one ground outer lead with larger cross section area than other outer leads. Therefore, the heat generated by the electronic device can be conducted outside through the ground outer lead when the ground outer lead is connected to other device.
