Abstract

A package structure includes a base body having a first encapsulant and a wiring layer embedded in and exposed from the first encapsulant. The wiring layer has a plurality of conductive traces and a plurality of first electrical contact pads. The first encapsulant has openings for exposing the first electrical contact pads, a chip electrically connected to the wiring layer, and a second encapsulant formed on the base body for covering the chip and the wiring layer, thereby providing an even surface for preventing the encapsulant from cracking when the chip is mounted.
