Elaplus Case Study on PCB Protection and Encapsulation of Bluetooth Sensor for Automobile Electric Tailgate
With the rapid development of automobile intelligence and electrification, electric tailgate has become one of the indispensable functional components in modern cars. As the core part of this system, the Bluetooth sensor PCB not only requires precise signal processing and connection functions, but also must be able to withstand harsh conditions in the automotive environment, including high temperature, humidity, vibration, salt spray and other complex environments. Therefore, the requirements for its protection have become increasingly strict. In this context, choosing a suitable potting material has become the key to ensuring the stability of PCB performance and extending product lifespan. 01 Background and ChallengesWith the continuous advancement of intelligent car technology, electric tailgate has become an important component of high-end car configurations. The electric switch and closing function are precisely controlled through intelligent components such as Bluetooth sensors, therefore, the stability of the sensor PCB is crucial to the performance of the entire tailgate system. However, sensor PCBs must withstand various extreme conditions in the automotive environment during long-term use, including: Temperature changes: Vehicles operate under extreme temperature differences between high and cold temperatures, and sensors need to maintain stability.Vibration and shock: Frequent tailgate opening and closing operations and road vibrations may affect the mechanical stability of the PCB.Moisture and water boiling: Rainwater or humid environments may cause electronic components to become damp or short-circuit.Salt spray corrosion: Salt spray corrosion in coastal areas or during winter poses protection requirements for onboard electronic devices.02 Solution: EP 1713 two-component solvent-free ambient temperature curing epoxy sealantIn order to address the above challenges, EP 1713 two-component solvent-free ambient temperature curing epoxy sealant has become an ideal choice. This product has excellent adhesion, crack resistance, and thermal conductivity, making it very suitable for potting protection of electronic components. Below, we will analyze in detail the advantages…
