Abstract:
A thermal enhanced ball grid array package, comprising:a substrate, including: a metal core layer having a first surface and a second surface opposite to the first surface, with the first surface having a die pad region and the second surface having a corresponding die pad region; a first patterned trace layer provided in a region adjacent to the die pad region on the first surface, wherein a first insulating layer is provided between the first patterned trace layer and the metal core layer; and a second patterned trace layer provided on the second surface, with a second insulating layer being provided between the second patterned trace layer and the metal core layer, wherein the second patterned trace layer has a plurality of ball pads around the corresponding die pad region of the second surface of the metal core layer to electrically connect to the first patterned trace layer, and a plurality of blind vias are formed under the corresponding bonding pad region of the metal core layer through the second patterned trace layer and the second insulating layer; a chip attached on the die pad region of the first surface of the metal core layer and electrically connected to the first patterned trace layer; a molding compound to encapsulate the chip an part of the connection of the chip and the first patterned trace layer; a plurality of solder balls provided on the surfaces of the ball pads; and a plurality of thermal balls integrally formed through the blind vias.
