Masking Boots for Conformal Coating

Posted by Sean Horn on Fri, Mar 09, 2018 @ 07:33 AM

With proper equipment and professional expertise, liquid conformal coatings and vapor-applied parylene readily provide printed circuit boards (PCBs) and similar electronics a durable overlay of protective, insulative film; parylene’s CVD processes ensure the coating actually penetrates the substrate surface, generating further device security.

Parylene Masking: Materials and Methods

Posted by Sean Horn on Fri, Jan 06, 2017 @ 07:45 AM

Parylene deposition takes place at the molecular level.  Applied at room temperature through CVD processing, the typical thickness of parylene conformal film is in the microns-range.

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 depositing parylene on a clean hydrophobic surface before its chemical vapor deposition (CVD) process is enacted.

Parylene Masking Revealed

Posted by Sean Horn on Wed, Aug 14, 2013 @ 09:07 AM

Whether the application is a medical device, a printed circuit board (PCB), or a light-emitting diode (LED), a parylene conformal coating is typically applied to protect the product. Sometimes, however, the product actually has to be protected from the parylene conformal coating—or at least parts of it do.
