Abstract

The invention relates to a double-sided SiP three-dimensional packaging structure, which includes a core adapter board (1). The core adapter board (1) is mounted on the front with a fan-out wafer-level packaging structure (2), a first passive component (3) and the first 3D conductive component (4). The core adapter board (1) is mounted on the back with the chip (7), the second passive component (8) and the second 3D conductive component (6), so A first solder ball (10) is provided on the back of the second 3D conductive component (6), a shielding layer (15) is provided on the top and side surfaces of the packaging structure, and the shielding layer on the front of the first 3D conductive component (4) The layer (15) is provided with openings (16). The present invention can use prefabricated 3D conductive components to become the support structure of the stacked package, and use the 3D conductive components as the grounding end of the electromagnetic shielding, which can reduce the size and height of the package module, improve the high-frequency performance of the package module, and effectively prevent electromagnetic interference. .

Description

technical field [0001] The invention relates to a double-sided SiP three-dimensional packaging structure, which belongs to the technical field of semiconductor packaging. Background technique [0002] According to the development of semiconductor technology, electronic devices have become miniaturized and lighter to meet users' needs, and thus, multi-chip packaging technology for realizing the same or different semiconductor chips from a single package has been enhanced. The multi-chip package is advantageous in terms of package size or weight and mounting process compared to a package realized by a semiconductor chip, and in particular, the multi-chip package is mainly applied to a portable communication terminal requiring miniaturization and weight reduction. [0003] However, with the high-density circuits in the packaging process, the use of various packaging materials, and the use of various chips and functional devices, the entire package is very complicated, and the m...
