2023 / 03Introduction to Testing Methods for Flatness of Module Bottom Surface
The application thickness of thermal conductive silicone grease during module installation depends on the flatness of the module bottom. For modules with good bottom flatness, if the thermal conductive silicone grease is applied too thick, it will form a film in the middle of the contact surface, which actually hinders direct contact of metals. Although the thermal conductivity of thermal conductive silicone grease is better than air, it is not as good as metal. Therefore, the accurate judgment of the flatness of the module bottom surface affects whether the temperature rise of the module in the system can be further optimized. The following text mainly introduces several tools and methods for detecting the flatness of module bottom surface, hoping to be helpful for readers to understand the concept of module bottom surface flatness.
