Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically to an integrated sensor packaging structure. Background Technology

[0002] A sensor is a detection device that senses measured information and converts it into electrical signals or other forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording, and control. Sensors are an important component of modern technology and are widely used in many fields such as industry, agriculture, medicine, and the military. They are a key link in realizing automated detection and automatic control.

[0003] An integrated gas sensor packaging structure, as disclosed in publication number CN205879844U, includes a substrate, multiple pins, an integrated cap, and a chip unit. The chip unit is placed on the top surface of the substrate, and the multiple pins are respectively disposed on the bottom surface of the substrate. The integrated cap covers the chip unit, with its bottom surface bonded to the top surface of the substrate, and at least one detection port for gas detection is formed on the top surface of the integrated cap. This invention provides a miniature packaging solution for MEMS gas sensor chips and integrated circuit chips, offering advantages such as small size and light weight. It can package multiple gas sensor chips and integrated circuit chips, improving integration density, further reducing the overall sensor size, and enhancing the sensor's overall performance. The use of borderless technology, directly bonding the integrated cap to the substrate, simplifies the process and increases the yield rate.

[0004] The aforementioned devices are inconvenient to install during use, difficult to replace when damaged, and lack protective devices; therefore, we propose an integrated sensor packaging structure to solve the problems mentioned above. Utility Model Content
