Abstract

The embodiment of the invention relates to a board-level fan-out chip packaging device and a preparation method thereof. A recess is formed in one side of a bearing board used for bearing a chip, the size of the recess is matched with the size of the back side of the chip, and the chip is mounted in the recess. When the chip is mounted to the bearing board, the recess in the bearing board exactly accommodates the back side of the chip, so that the chip to be packaged is easy and convenient to put in place. According to the invention, the dependence of fan-out packaging on the format of a chip mounter and chip mounting precision is eliminated, so that the development of the large-format fan-out chip packaging technology is facilitated.

Description

technical field [0001] The present invention relates to the technical field of chip packaging, and more particularly, to a fan-out chip packaging device and a preparation method thereof. Background technique [0002] With the continuous development of information technology and semiconductor technology, electronic devices such as mobile phones, PADs, and smart watches are gradually becoming lighter and more functionally integrated. This requires higher and higher integration levels of chips, which in turn brings unprecedented challenges to chip packaging. Growing interconnect pitch mismatch, adding various chips with different functions, and reducing package size in the same footprint to increase battery size and extend life have all opened the window for innovative embedded packaging technologies. [0003] Benefiting from the development of 3D through-silicon via (TSV) technology, fan-out wafer level packaging (FOWLP) is currently considered to be the most suitable for the...
