Common Parylene Problems

Posted by Sean Horn on Fri, Jul 15, 2016

In addition to cracking, a range of associated issues may interfere with successful coating of parylene films.  Because it is applied via CVD, parylene generates a structurally continuous film covering a PCB or similar assembly.  In CVD, the interaction of vapor-phase chemical reactants formulate a non-volatile solid film on a substrate, useful for a variety […]

Parylene for LEDs

Posted by Sean Horn on Fri, Mar 4, 2016

LED Lifespan as Effected by UV Light Although LEDS are designed to provide as many as 100,000 hours of illumination under laboratory conditions, they are not nearly as resilient when subjected to persistent real-world, real-time usage.  Sensitive to electrical interference, moisture, UV light, and other persistent sources of physical damage, LEDs require protection to operate […]

Causes of Parylene Delamination

Posted by Sean Horn on Fri, Feb 26, 2016

Delamination Problems of Parylene Conformal Coatings Providing a uniform and pinhole-free substrate coating that is ultra-thin, lightweight and durable, parylene coatings completely conform to targeted components and assemblies.  Parylene CVD generates a structurally continuous film that, with appropriate pre-treatment, penetrates deep within substrate surfaces, rather than simply attaching thems
