The Parylene Deposition Process

There are several variables that influence the Parylene coating process, including the substrate material, cleanliness, and preparation. Through understanding the variables that can impact the coating process, SCS’ team has mastered the art of building the right process, which means the successful coating your application.

Below is an overview of the Parylene coating process:

  1. Substrates to be coated are placed in the coating chamber.
  2. Parylene raw material (dimer) is placed in the system.
  3. The powdered dimer is vaporized into a dimeric gas. This gas is then pyrolized into monomeric gas.
  4. The monomeric gas enters the ambient temperature coating chamber and polymerizes on all surfaces, completing the coating process. The substrates are now protected with ultra-thin Parylene.
