How Fast Does Parylene Deposit?

Posted by Sean Horn on Fri, Nov 20, 2020

Parylene conformal coatings combine a number of properties that are attractive for use in a wide spectrum of applications. Their low dielectric properties, high mechanical strength, transparency, bio compatibility, chemical inertness against all of the common acids, bases and organic solvents, low water/gas permeability and thermal properties make them interesting for use in many industries.

What Temperature Will My Parts See During the Parylene Coating Process?

Posted by Sean Horn on Fri, Nov 13, 2020

Parylene coating process involves 3 steps: sublimation, pyrolysis, and polymerization. At the first step, which takes place between 120°C – 175°C, the dimer parylene powder precursor is sublimized and pyrolysed forming the monomers (see Figure). Next, Pyrolysis takes place which is defined as the thermal decomposition of materials at elevated temperatures (above 500 °C) in […]

Best Coatings for Medical Devices

Parylene is a polymeric material that is commonly applied as a conformal coating layer in electronic applications. Parylene conformal coatings are used to provide environmental and/or dielectric isolation. They offer pinhole-free layers with low water permeability, high flexibility and high mechanical strength (see table). While parylene coatings are most frequently applied onto the electronic cir
