Why Conformal Coating Is Essential for Our Ceiling Fan Controller's PCBA

       In our ceiling fan controllers, the PCBA is protected by a thin layer of conformal coating, also known as "three-proof paint." This coating is vital for defending the circuitry against moisture, dust, and corrosion—common issues that can lead to premature failure.

       Without this protective coating, the PCBA in our controllers would be vulnerable. Moisture in the air can cause corrosion on the copper traces, and dust accumulation can lead to overheating or short circuits over time. This is especially important for devices like ceiling fans that may operate in humid or dusty environments.

       Compared to an uncoated PCBA, our coated boards have a significant advantage. The coating acts as an invisible shield, dramatically improving reliability. This means our controllers are built to last longer and perform more stably, reducing the risk of malfunctions for our customers.

By using conformal coating, we ensure that the electronic heart of your fan controller is well-protected, providing peace of mind and long-term value.
