The answer was a conformal coating. Conformal coating is a protective polymer film or chemical coating that seals off the vulnerable circuits. This coating acts like a barrier that shields the flex circuit board from things like dust, moisture, and other environmental contaminants.
Most conformal coatings come as a spray, and manufacturers can choose from several different types depending on the needs of a specific product. If you have questions about conformal coating for your flex printed circuit boards, contact GC Aero today.
Printed circuit boards are delicate, and interference by things like dust, humidity, or moisture could damage circuit boards and dramatically lower the efficiency of the electronic device. Since consumers expect their electronic devices to work in dusty, humid, hot, and cold environments, flex circu...
