Differences between Parylene and Acrylic Conformal Coating

Posted by Sean Horn on Fri, Apr 17, 2015 @ 09:00 AM

Parylene and acrylic conformal coatings represent two extremes of the types of compounds you can use to coat printed circuit boards, sensors, or other devices. While acrylic is popular and inexpensive, parylene offers some of the best performance of any coating compound.

Best Conformal Coating for Humid Environments

Posted by Sean Horn on Fri, Apr 10, 2015 @ 08:43 AM

Just about every major type of conformal coating provides protection against moisture. If you get a printed circuit board coated with epoxy, acrylic, urethane, silicone or parylene wet, typically all that you have to do is wipe it off. Environments with high humidity pose a different set of challenges. Because moisture is omnipresent in humid environments, the conformal coating doesn't just have to resist water ingress. It also needs to completely seal the coated item. Given this additional requirement, the best choice will usually be either silicone or parylene.

Is Parylene Coating Bio-compatible?

Posted by Sean Horn on Fri, Apr 03, 2015 @ 09:27 AM

Parylene is the most bio-compatible conformal coating currently available. Its chemical properties make it a natural for use in medical and biological applications. In addition, some of its general benefits also make it particularly valuable in healthcare applications. Finally, parylene also enjoys a stringent USP Class VI bio-compatibility certification.

How Easy is Parylene to Rework?

Posted by Sean Horn on Fri, Mar 27, 2015 @ 08:32 AM

When it comes to reworking, parylene's strengths are also its biggest drawbacks. In addition to its ability to comprehensively coat substrates, it is also, by design, very challenging to remove. However, "very challenging" and impossible are two different things. Furthermore, good planning strategy before coating can also help to reduce the need for parylene rework.

Parylene Conformal Coating for Medical Use

Posted by Sean Horn on Fri, Mar 20, 2015 @ 09:29 AM

Parylene conformal coatings have protected medical device components with an extended range of applications for over 40 years. They offer both patients and medical personnel the most reliable level of uniform, biocompatible device-security for cardio- logical and surgical procedures.  Their value and application proliferate, as technology develops.  

Organic Polymers used as Coatings

The overall generic name parylene designates a unique set of organic polymeric coating materials with innumerable applications.  All commercially applied parylene configurations are polycrystalline and linear in nature.

Drawbacks of Parylene Coating

Posted by Sean Horn on Thu, Mar 05, 2015 @ 02:09 PM

Parylene has a well-deserved reputation as one of the leading choices for conformal coatings. For many applications, it is the best choice. However, there are some real parylene disadvantages, as well. For many applications, other conformal coatings such as acrylic, epoxy, silicone or urethane offer better performance, lower cost or both.

Protecting MEMS with Parylene Coatings: No Small Feat

Posted by Sean Horn on Fri, Feb 27, 2015 @ 01:08 PM

As engineers continue to seek out the most powerful technologies packed into the smallest footprints possible, the use of microelectromechanical systems (MEMS) are on the rise. At the forefront of progress in miniaturization, MEMS enable small form factors without sacrificing precision and reliability. In many cases, MEMS technologies even offer an increase in performance over their larger, traditional counterparts. MEMS technologies can also be produced at low cost, owing to the use of semiconductor fabrication methods.
