What You Need to Know About Aerosol Spray Conformal Coating

Aerosol Spraying conformal coatingAerosol spray is one of the most common application methods for low volume conformal coating processing. The use of an aerosol spray can allows fast entry and coating across circuit boards.

Conformal coating aerosols are just like batch spraying wherein the process is all inclusive and not selective. Thus, this process May require a certain level of masking on circuit parts that don’t require coating.

The Basics

  • Solvent-based conformal coatings mostly come in aerosol cans.
  • A spray booth is needed during aerosol application where it is safe to use atomized coating.
  • No prior blending or mixture is required for aerosol application.
  • It requires skill, knowledge, and training to have high quality coating finish.
  • It is cost efficient and ideal for low and volume coating.

Variables to consider in aerosol spray conformal coating finish:

  • The operator’s skill and extensive training.
  • The volume of solids or solvent percentage.
  • The masking level needed.

Conformal coating using aerosol spray has its own set of advantages and disadvantages. Some of the benefits involve fast completion, easy execution, and low cost. On the flipside, quality control of the coating is dependent on the operator and additional masking cost.
