Troubleshooting Conformal Coating Contamination


Contamination on the circuit board on top of the conformal coatingContamination happens when debris is trapped or found on the conformal coating of the printed circuit board. This can affect the reliability of the board over time.

Origin of Contamination:

Contamination can occur during the following situations:

  • Pre-production stage
  • Processing stage (during application)
  • Drying or curing stage
  • During the lifetime of the product

Preventing Contamination:

Contamination during the conformal coating process can be avoided by:

  • Improving cleanliness prior to production.
  • Having an efficient cleaning process prior to conformal coating.
  • Ensuring a safe and effective process after the coating.
