Full analysis of Hall sensor encapsulation process | Professional protection to enhance reliability

Hall sensors are an important type of magnetic field sensing device widely used in fields such as automotive electronics, industrial control, and consumer electronics. Due to its use of non airtight packaging, it is highly susceptible to external media and mechanical impacts in harsh environments such as high temperature, humidity, oil, vibration, etc. without effective protection. Therefore, potting and conformal coating are key components in the reliability design of Hall sensors. Sealing: Injecting sealing material into the interior of the shell to form a complete package, providing electrical insulation, protection, and mechanical reinforcement; Coating overlay: forming a thin film layer on the surface of PCB or sensitive components, mainly used for moisture, dust, and basic chemical protection.1、 Environmental and mechanical protection methods
