SIDE-WETTABLE SEMICONDUCTOR PACKAGE DEVICE WITH HEAT DISSIPATION SURFACE STRUCTURE

A die of the package device is covered by an encapsulation layer, a plurality of lead portions are configured on the bottom surface of the encapsulation layer, a side portion of each lead portion is also exposed on a side surface of the encapsulation layer, and thereby the package device is used as a side-wettable package device; wherein, in a process of manufacturing the package device, a conductive electroplated conducting layer is formed on the surface of the encapsulation layer, and the electroplated conducting layer is used to conduct electric power required during an electroplating process. After the electroplating process is completed, the electroplated conducting layer can be used as a heat dissipation layer for the package device. The heat dissipation layer completely covers the surface of the package device so as to increase heat dissipation area and to be attached by a heat sink.
