Parylene Coating: Does Thicker or Thinner Coating Provide Better Performance?

Posted by Sean Horn on Fri, May 25, 2018

Parylene (XY) conformal coatings are known and recommended because of their many beneficial performance characteristics.  They provide uniform, pinhole-free protective films with excellent barrier/dielectric/insulative properties, able to conform to virtually any substrate configuration.  One property in particular – micron-thin coating layers – distinguishes XY from liquid coating materials

Conformal Coatings Thickness: Comparing Parylene with Liquid Coatings

Of the five most commonly used conformal coatings, four – acrylic (AR), epoxy (ER), silicone (SR) and urethane (UR) – are classified as wet materials, meaning they are applied to substrates by three basic types of liquid-based technology:

Parylene Effectiveness at Different Thicknesses

Each conformal coating material exhibits a range of unique performance properties that determine its product uses.  Relevant factors include the required coating-thickness necessary to assure reliable performance.  Like other coating types, parylene (XY) layer thickness is largely a function of several factors:  (1) substrate material, (2) the kind of assembly being covered, and (3) its [&helli
