Nano Coating vs Parylene

Posted by Sean Horn on Fri, Feb 24, 2017 @ 08:00 AM

Although its basic component is remarkably small – with 25,400,000 nanometers included in just one inch(!!) -- nanotechnology encompasses a growing, interdisciplinary field with an unlimited future.  Nanowires and nanotubes are used in transistors for printed circuit boards (PCBs) and associated electronic assemblies.  Bio-nanobatteries, capacitators, LCDs, and microprocessors represent just a few nano-applications, which include uses for aerospace, agricultural, automotive, consumer, industrial, medical, military and oceanic products.

Disadvantages of Using Parylene on Electronics

Posted by Sean Horn on Fri, Sep 23, 2016 @ 07:30 AM

Despite parylene’s numerous benefits as a conformal coating, it has several disadvantages that should be recognized before it is used.  Failure mechanisms that can emerge from parylene coatings have limited its wider scale application in comparison to liquid conformal films such as acrylic, epoxy, silicon, and urethane.  In many situations, wet coatings can provide better performance and lower cost (or both) for many applications

5 Key Properties of Parylene

Posted by Sean Horn on Tue, Jan 07, 2014 @ 09:42 AM

Since its discovery in the 1940s, Parylene has skyrocketed to prominence as an ideal conformal coating choice for a range of applications. Given its unique blend of properties, it might seem like an unparalleled conformal coating option. In many ways, it is. Here are five key properties of Parylene that differentiate it from the rest.

Ultraviolet (UV) Stability of Parylene

Posted by Sean Horn on Wed, Oct 23, 2013 @ 09:48 AM


For all of Parylene's strengths, it has one key drawback—Parylene's resistance to ultraviolet (UV) radiation is limited. Most formulations of Parylene gradually yellow when exposed to the kind of UV light that's produced by the sun. While this isn't a problem when Parylene gets used to conformally coat a printed circuit board that's sealed in a box, it can be a problem when a display made of Parylene-coated LEDs is installed outdoors.

Parylene Disadvantages

Posted by Sean Horn on Wed, Oct 17, 2012 @ 09:51 AM

Parylene offers the best protection against solvents of any conformal coating.  It is also brings to the table excellent moisture and gas protection, very high dielectric strength, and is bio-compatible.  Even with all of these benefits, there are still some disadvantages to using parylene versus other conformal coatings.
