Abstract

A package substrate based on a molding process may include an encapsulation layer, a support frame located in the encapsulation layer, a base, a device located on an upper surface of the base, a copper boss located on a lower surface of the base, a conductive copper pillar layer penetrating the encapsulation layer in the height direction, and a first circuit layer and a second circuit layer over and under the encapsulation layer. The second circuit layer includes a second conductive circuit and a heat dissipation circuit, the first circuit layer and the second conductive circuit are connected conductively through the conductive copper pillar layer, the heat dissipation circuit is connected to one side of the device through the copper boss and the base, and the first circuit layer is connected to the other side of the device.
