Abstract
A chip package structure and an electromagnetic interference (EMI) shielding package module thereof are provided. The EMI shielding package module includes an encapsulant, an EMI shielding layer, and a recognition contrast layer. The encapsulant has a patterned trench that is recessed in a top surface thereof. The EMI shielding layer includes a recognition region formed on the top surface and an embedded region that is filled in the patterned trench. The recognition contrast layer is filled in the patterned trench and is connected to the embedded region. The recognition contrast layer and the recognition region respectively have different colors that conform to grade A or grade B in ISO/IEC 15415 standard. An end portion of the recognition contrast layer protruding from the top surface is coplanar with the recognition region so as to jointly form a predetermined two-dimensional (2D) code pattern having a planar shape.
