There are a number of reasons for the use of circuit board protection. This could include, but is not limited to: harsh environments caused by chemicals, moisture, and exposure to other contaminates, mechanical protection from vibration, shock and temperature cycling, electrical Insulation either from the environment or from the assembly. Additionally, the requirement for proprietary design protection is becoming increasingly important. Therefore, some circuit board protection options can be used to slow down or prevent reverse engineering of proprietary assemblies.
