When Should I Use Conformal Coating?
The coating is skinny, making it an excellent choice for some circuit boards and devices, particularly those with strict weight or thickness restrictions.

Circuit boards in cell phones, for instance, are often put in tiny spaces. In situations like these, conformal coating is a perfect option.

How do conformal coatings work?
A conformal coating is a defensive boundary that shields sensitive electronic parts against cruel natural conditions, for example, dampness, chemicals, and debris. Conformal coatings are a breathable protective layer that will protect against the particular environmental requirement yet keep any water caught in the circuit board away. They are not designed to be a total sealant.

The particular advantages of conformal coatings can be summarized as follows:
1. Insulating properties allow a reduction in PCB conductor spacing of more than 80%.
2. Completely protect the assembly against chemical and corrosive attacks.
3. Eliminate potential performance degradation due to environmental hazards.

Finally, the conformal coating allows protection without significant additions to the weight or thickness of the device.
