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 […]

Can Parylene Be Layered?

Posted by Sean Horn on Fri, Oct 2, 2020

Multilayer conformal coatings are advantageous in resolving diffusion or stability issues. A vast amount of knowledge is available in the literature about the use of multilayered stacks of parylene and stacks making use of different intermediate materials such as metals and so on. Use of multiple layers of parylene C was most commonly reported for […]
