What’s the difference between a surface modifier and a conformal coating?

Surface Modifiers is an ultra-thin coating that is applied at a few microns in thickness.

In contrast, liquid conformal coatings are typically applied in the range of 25-75 um thus being thicker in nature.

Two of the most popular types of these ultra-thin coatings are:

  • Liquid materials which dry onto the substrate
  • Materials which are applied in a partial vacuum

The change in energy that a surface modifier creates when applied to a circuit board makes it harder for liquids like water and oiled to wet the surface and cause damage.
