Elaplus case sharing of miniature inductor encapsulation and fixation
In the field of industrial electronics, miniature inductors are often used in various precision equipment, especially in communication, automation control, and electronic control systems for new energy vehicles. Ensuring the reliability and stability of micro inductors under extreme conditions such as high temperature, low temperature, and mechanical vibration has always been a major challenge in electronic component design, as they need to withstand various harsh working environments. In order to ensure the long-term stability of micro inductors, packaging and fixing techniques have become the key to solving this problem. The selection of sealant needs to consider multiple aspects, including adhesive strength, toughness, thermal stability, seismic resistance, etc. Choosing the appropriate sealant can significantly improve the anti-interference ability, seismic resistance, and temperature resistance of inductors. In this situation, the main challenge faced by the customer is how to improve the stability of the miniature inductor under extreme temperature changes, while ensuring that the inductor will not be damaged under mechanical vibration and impact. Specific issues include: material expansion under temperature difference changes: Micro inductors often operate in high and low temperature environments, and expand and contract during temperature changes, which can easily lead to stress concentration in components and affect the stability of inductors. Seismic requirements: Inductors must have certain seismic resistance in practical use, especially in electric vehicles and high vibration environments, to prevent solder joint breakage or inductance detachment. Environmental tolerance: Micro inductors are often exposed to extreme working environments, such as high temperatures, high humidity, or dusty environments in automotive electronic control systems. Therefore, sealing materials must have excellent properties such as high temperature resistance, low temperature resistance, water resistance, and corrosion resistance.
