How to Choose Between Potting and Conformal Coating

Posted by Sean Horn on Fri, Oct 14, 2016 @ 07:31 AM

            Protection of printed circuit boards (PCBs) is most often achieved with either potting or conformal coating.  The selection of which method to use depends upon the PCB’s purpose and how much protection it requires.  Potting offers the strongest shielding barrier, but is also affected by a range of operational disadvantages that can offset its functional benefits.  Conformal coatings generate reliable barrier protection, which frequently circumvent the problems inherent in potting.  This is particularly the case with parylene, a non-liquid conformal coating.

Parylene vs Potting

Posted by Sean Horn on Fri, Jul 03, 2015 @ 08:16 AM

If you have a printed circuit board or other item that needs protection, you typically have a choice between potting and conformal coating. While potting offers the largest and most powerful barrier against the outside world, it also carries some significant drawbacks. Conformal coating, especially with parylene, also offers a protective barrier, but does it without the challenges that potting poses.
