发明名称 Semiconductor package with fastened leads
摘要 A semiconductor package primarily comprises a plurality of leadframe's leads, a chip, a paddle, an adhesive and an encapsulant encapsulating the components mentioned above. The paddle has a carrying surface and an exposed external surface. The first chip is attached to one surface of the leads. The paddle is attached to an opposing surface of the leads by the adhesive bonding the carrying surface to the leads. Furthermore, the adhesive further encapsulates the gaps between the leads without contaminating the exposed external surface and with the exposed external surface exposed from the encapsulant. Therefore, the leads obtain a better support so that the encapsulated portions of the leads will not shift nor expose from the encapsulant during molding processes without encapsulated bubbles between the leads and the paddle. The heat dissipation is also enhanced.
