Abstract

The present invention proposes a high-density integrated navigation, positioning and timing micro-device and its integration method, using the system architecture of four-layer assembly substrate, two side substrates and one bottom plate, adopting multilayer LTCC technology and ceramic thick film substrate technology to integrate each Similar functional chips are assembled on the substrate, using flexible baseband interconnection technology and solder ball technology to realize electrical signal connections between substrates, between substrates and bottom panels, and between substrates and side panels, and using three-dimensional high-density assembly technology to achieve three-dimensional high-precision assembly of multiple substrates. And the high-density integrated heat dissipation technology is used to realize the chip-level and package-level heat dissipation treatment of the three-dimensional chip stacking system, which effectively reduces the physical volume of the system and enhances the heat dissipation performance of the system.

Description

technical field [0001] The invention belongs to the field of integrated manufacturing and application of micro-electro-mechanical systems, and in particular relates to a high-density integrated navigation, positioning and timing micro-device for micro-platforms and an integration method thereof. Background technique [0002] With the development of modern science and technology, vehicles, aircraft, ships, and weapon systems have put forward higher and higher requirements for navigation systems. Traditional single navigation methods such as inertial navigation, global satellite navigation (GNSS), geomagnetic navigation, and electronic maps etc. cannot meet the application requirements, therefore, more and more modern navigation adopts a combination of multiple navigation methods, that is, composite navigation. [0003] Composite navigation improves the accuracy, anti-jamming capability and redundancy of the navigation system. However, most of the current composite navigation...
