Analysis reveals that crimping-formed sealing enhances reliability in automotive pressure sensors, indicating a robust encapsulation method.
To ensure safe and stable operation of electronic components and functional structural components of automotive pressure sensors under complex working conditions, they shall be sealed and encapsulated. In this paper, the automotive pressure sensors are encapsulated with metal shell crimping-formed and sealing method. The process of crimping-formed and sealing is simulated and analyzed. The structure of crimping-formed and sealing is optimized with response surface method. The reliability of its encapsulation is verified through experiment. The results show that the crimping-formed and sealing process can effectively improve the long-term reliability of the sensors by forming a sealing interface through metal plastic deformation, and provide a new solution for the encapsulation of automotive pressure sensors.
