Description

technical field [0001] The invention relates to the technical field of semiconductor packaging, in particular to a semiconductor packaging structure and a preparation method thereof. Background technique [0002] In the existing antenna mobile phone terminal applications, the antenna transmits and receives signals through the combination of multiple functional modules (such as active components and passive components) and the antenna. The traditional packaging structure is to combine each functional module And the antenna is assembled on the PCB board. In the above structure, the functional modules and antennas are arranged on the surface of the PCB board, which will occupy a large area of ​​the PCB board, so that the entire packaging structure has long lines for transmitting signals, poor electrical properties and antenna performance, and high power consumption. And the problem of large package volume. Contents of the invention [0003] In view of the above-mentioned sh...
