Key Findings
Henkel’s Bergquist® HI-FLOW THF 1600P, a high-performance phase-change thermal interface material (TIM), has been successfully integrated into next-generation motor controllers, effectively addressing demanding power density and efficiency requirements. This implementation has demonstrably improved customer field reliability, leading to a significant reduction in field returns by 20% to 40%.
Technical / Clinical Details
The Bergquist® HI-FLOW THF 1600P features a thermal conductivity of 1.5 W/m-K. It is solid at room temperature but transitions to a liquid-like state upon reaching its phase-change temperature, allowing it to conform perfectly to microscopic surface irregularities between components (e.g., IGBTs, MOSFETs) and heatsinks. This ensures minimal thermal resistance and highly efficient heat transfer. Rigorous testing has validated its robust performance, including excellent temperature cycling stability and no degradation after 500 hours at 120°C. This exceptional durability is critical for motor controllers, which often operate in environments with continuous thermal fluctuations. By maintaining optimal operating temperatures, the TIM extends the lifespan of internal components, thereby enhancing the overall reliability of the motor controller system.
Background & Context
The electric vehicle (EV) and industrial motor sectors are increasingly pushing for more efficient and compact motor controllers. This trend invariably leads to higher power densities within the controllers, making thermal management a paramount concern. Excessive heat can severely degrade semiconductor performance and lead to premature failures, underscoring the indispensable role of reliable thermal interface materials. The successful deployment of Henkel’s Bergquist® HI-FLOW THF 1600P highlights the material’s ability to meet these escalating demands, providing a robust solution for critical thermal challenges in high-power applications.
Strategic Significance & Outlook
The demonstrated 20-40% reduction in field failures for motor controllers adopting Henkel’s Bergquist® HI-FLOW THF 1600P establishes a strong competitive advantage for this TIM in the market. This success is expected to drive broader adoption of similar phase-change TIM solutions across other sectors requiring high reliability and efficiency, such as renewable energy systems, industrial robotics, and data center power supplies. Henkel is well-positioned to leverage this proven technology to further develop and introduce advanced thermal management solutions that are not only high-performing but also environmentally conscious, continuously meeting the evolving and increasing demands of the global electronics industry.
