Conformal coatings are applied to printed circuit boards (PCBs) to protect them from environmental stress such as salt, corrosion, humidity, and moisture, mitigate tin whiskers, and provide a barrier to electrically insulate components.

Shielding printed circuit boards from environmental damage is the primary purpose for using light-cure conformal coatings.

A few of the more common Q&As are summarized below:

In the new era of connectivity, Electromagnetic Interference (EMI) is an important consideration when working with electronic components.

Manual brushing is just one of many methods commonly used for applying conformal coating materials to PCBs and other components. It is a hand-applied method that requires little investment into automation or equipment. With practice, it can be one of the simplest methods available, especially for small-batch production or isolated applications.
