While they may not always perform a particular electrical function, they are the most effective way to increase circuit lifespan in harsh or rough service environments.  After you've read 5 Reasons to Use Conformal Coatings on PCBs post, you're probably ready for the next step.

Here are 10 Questions you need to ask yourself before choosing a conformal coating for your application:

  1. What is the end environment for the board?
  2. What requirements do you have for the coating? ( UL, MIL, IPC)
  3. Will you have shadow areas on your board?
  4. Are you looking for secondary heat or moisture cure?
