The Impact of Temperature on Parylene Adhesion

Posted by Sean Horn on Fri, May 20, 2016

Basic Thermal Properties of Parylene Conformal Coatings  CVD-generated parylene combines high thermal stability with a low dielectric constant, minimal moisture absorption, and other advantageous properties which sustain its adhesion to substrate surfaces.  Among the most beneficial of the parylenes’ thermal properties is their ability to function at an exceptional range of temperatures.  Dep

Characteristics of Noble Metals Selecting the appropriate pre-treatment procedures is a key factor to this success of parylene adhesion to any substance.  Procedures vary quite considerably, according to the materials designated for conformal coating and substrate.  Chemically inert surfaces like gold, silver and other noble metals, and nonpolar thermoplastics such as parylene, are extremely dif

Surface Treatments Prior to Parylene Coating

Pre-coating Essentials Poor parylene adhesion negates many of the coating’s most-valued functional properties, including dielectric strength, and resistance to the effects of chemicals, corrosive agents, and moisture.  Surface treatments that amplify the interface adhesion between the deposited parylene and the coated substrate are therefore highly desirable.  These treatments entail depositin
