Understanding Parylene Deposition

Posted by Sean Horn on Fri, Jul 31, 2015 @ 08:10 AM

Parylene's deposition process is unique among conformal coatings. Unlike others that start as a liquid, get deposited and dry, it starts as a solid. Parylene coating equipment turns it into a vapor, where it then deposits onto the substrate. This unique four-step method poses some challenges but also brings real advantages.

Things to consider when Choosing a Parylene Coating Service Provider

Posted by Sean Horn on Fri, Jul 10, 2015 @ 07:58 AM

Choosing parylene gets you half way to protecting your company's products with the best possible conformal coating.  To close the circle, unless you have invested in the proper equipment and training, you also need to choose the right service to apply the coating. The Parylene coating industry, while it is a fairly niche business, is still a competitive market, but the very few top-quality providers are relatively easy to identify. Here are some of the attributes that you should actively seek:

Parylene vs Potting

Posted by Sean Horn on Fri, Jul 03, 2015 @ 08:16 AM

If you have a printed circuit board or other item that needs protection, you typically have a choice between potting and conformal coating. While potting offers the largest and most powerful barrier against the outside world, it also carries some significant drawbacks. Conformal coating, especially with parylene, also offers a protective barrier, but does it without the challenges that potting poses.

Printed Circuit Boards and Parylene

Posted by Sean Horn on Fri, Jun 26, 2015 @ 08:00 AM

While Parylene can coat just about anything, one of its most common uses is for protecting printed circuit boards. Product engineers specify Parylene because it offers a unique blend of five capabilities.

Parylene and Wearable Devices

Posted by Sean Horn on Fri, Jun 19, 2015 @ 08:01 AM

Wearables are no longer emerging technology -- they are here. Whether a wearable item is a medical device like an insulin pump, a smart watch or even a finely woven piece of smart fabric, they all have one basic fact in common. All of them contain technologies that need protection from the outside world and, in just about every case; parylene is the most appropriate choice for protection.

Protecting LEDs with Parylene

Posted by Sean Horn on Fri, May 29, 2015 @ 08:00 AM

Light emitting diodes are gradually replacing all other types of lighting. As they move out of consumer electronics and into general purpose applications ,the demands on the technology are shifting. It's relatively easy to keep an LED safe when it is mounted in the front panel of a computer or hidden under a cover on an alarm clock. Protecting it when it is going to be exposed to the elements 24 hours a day, 365 days a year is more challenging.

Can parylene be used outdoors?

Posted by Sean Horn on Fri, May 22, 2015 @ 07:30 AM

Parylene can be used outdoors. However, it has one drawback that could limit its suitability in some outdoor applications: sunlight can yellow it. With this in mind, product designers specifying a coating for a product to be used where it will be subject to sunlight should carefully consider the coatings pros and cons before specifying it. Frequently, but not always, it remains the best choice.
