Why Should You Add Conformal Coating To Your Printed Circuit Boards?


Why Should You Add Conformal Coating To Your Printed Circuit Boards?

Every electronic is mainly made up of and functions on the performance of the printed circuit boards installed within. These circuit boards comprise of a number of components like battery, resistors, conductors, diodes, capacitors, transistors, and much more. It is very important that all these components are kept away from any environmental hazards and atmospheric threats like moisture, humidity, pressure, extreme temperatures, and the like. This is why it is important to have a conformal coating on your printed circuit boards. This element protects the sensitive circuits in your device to help them live longer and work better. Let us take a look at the various threats that can be encountered and protected by conformal coating, to have a reliable PCB assembly from India.

Moisture and humidity

This is one of the biggest threats not only for printed circuit boards, but all kinds of electronics and electrical. Moisture and humidity can result in all sorts of problems like hacking of the appliance, shocks, shorts, and other failures. The circuit board can be rendered inoperable if moisture or humidity attacks it. Conformal coating helps here. It won’t be able to protect your device from a torrential downpour, but it can definitely resist humidity and condensation, thus helping your device to stay protected and function for longer.

Extreme temperatures

Every electronic and appliance is comfortable to work in only a specific temperature range. Any kind of extreme heat or cold may damage it. Same is the case with printed circuit boards. Especially if your device is meant to be used outdoors, it will have to be able to withstand the extreme highs and lows of the environment that are experienced in scorching summers and chilling winters. A conformal coating on a printed circuit boards keeps it protected, and helps it to fight against extreme temperatures.


Dust is everywhere, and there is nothing that can be done to eliminate it. But, keeping your circuit board protected against it is one thing you can do. Dust can clog up a circuit board, especially due to electrostatic attraction. But, when you have a conformal coating on your board, it shields the inner working of a circuit board from dust.
