What Temperature is Parylene Applied At?

Posted by Sean Horn on Fri, Aug 3, 2018

Parylene (XY) conformal coatings are applied to substrate materials through a specialized chemical vapor deposition (CVD) process that completely eliminates the liquid phase of wet coatings.  No initiators or catalysts are involved in CVD polymerization, which synthesizes truly conformal protective film in-process.  This is in stark contrast to wet coating materials such as acrylic, epoxy, [&hel

Can I Glue to Parylene?

Posted by Sean Horn on Fri, Jul 27, 2018

With reliable moisture barrier properties, parylene (XY) conformal coatings generally have a hydrophobic surface when deposited onto substrates, causing liquids to form separate droplets on film surfaces.  While this outcome is useful for many XY applications, greater hydrophilic response, wherein XY molecules form ionic or hydrogen bonds with water molecules, can also be desired.  This [&hellip

In-Line Parylene Processing??

Posted by Sean Horn on Fri, Jun 29, 2018

The phrase “in-line parylene processing” is deceptive  because it does not accurately describe the method in which parylene (XY) is applied as a conformal coating.  It is true that some aspects of the traditional production line are relevant, but primarily in a fractional way. without the traditional station-to-station regimentation of standard in-line manufacturing processes.
