How do I know 100% of My Product was Coated with Parylene?
Parylene conformal coatings are highly reliable and are highly sought after in applications across the product spectrum, ranging from military sensors to medical implants. Because Parylene coatings are colorless (transparent), thin (micro-scale) and uniformly deposited all over the target surface, they are hardly visible to the naked eye. There are methods to detect, or test,... Read More >>
Brush Application of Conformal Coating
Conformal coatings’ functional value stems from their ability to safeguard printed circuit boards (PCBs) and similar electronics from external threats to their performance. Composed of acrylic, epoxy, silicone and urethane polymer resin, coatings also provide layers of insulative protection. These liquid coatings are applied to PCBs by wet methods, primarily by brush, dipping (component immersion)... Read More >>
Inspecting Parylene Coating
Parylene conformal coating (XY) offers insulative protection for intricate electronic circuit assemblies that need to perform under demanding conditions – facing potential chemical, electrical, moisture and vapor exposure. Applied using chemical vapor deposition (CVD), Parylene wicks deep into substrate surfaces, providing a level of protection that exceeds what liquid coatings like acrylic, epoxy, silicone and urethane can...

What’s the Difference Between Potting and Conformal Coating?
Printed circuit boards (PCBs) are an essential element of all electronic devices. Manufacturers must choose an appropriate method to protect their product’s most critical components from damage and harsh environmental conditions. That’s where this comparison of potting vs. conformal coating becomes invaluable — helping you select the right method of protection for your application and requirements. What... Read More >>
Removing Conformal Coating Instead of Repairing It
Sometimes problems with conformal coating are too complicated or difficult to repair. This can occur when bubbles develop in the coating during the application process. Bubbles cause voids in the coating that defeat its protective, insulating purpose, suggesting the need for removal. Other situations that lead to inadequate coverage, and may favor coating removal rather... Read More >>
Parylene Conformal Coatings for Oil & Gas Sensors
Parylene, a transparent polymer, provides seamless and void-free conformal coatings. Variants like Parylene N, C, D and Parylene HT® are crafted through molecular structure tweaks, each yielding distinct material properties for various applications. Among these derivatives, the fundamental type is Parylene N, derived from the poly-para-xylylene monomer. Parylene presents numerous benefits for application in the... Read More >>
What Is the Proper Adhesion Test for Conformal Coating?
Essential steps in researching conformal coatings include confirmed testing of coating properties as well as adhesion. An online search for “conformal coating adhesion test” results in a number of documented tests and standards. These include tests from the International Standards Board (ISO) and the American Society for Testing and Materials (ASTM). One must exercise caution,... Read More >>
Nadcap® Specifications for Conformal Coatings
The National Aerospace and Defense Contractors Accreditation Program The National Aerospace and Defense Contractors Accreditation Program (Nadcap®) provides cooperative global accreditation covering all aspects of product manufacture in the aerospace, defense and engineering industrial sectors, as well as for related industries. Product and process conformity assessment is the key to Nadcap’s industry-managed accreditation criteria, generating... Read More >>
How Parylene Protects Electronics in Harsh and Hostile Environments
Parylene comes from a series of polymers from paraxylene and is often used as a coating that safeguards electronic devices. Specifically, Parylene coating is a conformal coating applied at room temperature using a chemical vapor deposition (CVD) process. For many industries, Parylene shields electronics from contamination, corrosion and complications arising from exposure to harsh and hostile environments. Parylene Coatings... Read More >>
What Is Type XY Conformal Coating?
Type XY conformal coating, also known as Parylene, derives its name from its full chemical name, para-xylylene. To streamline its classification with other conformal coatings like acrylics (AR), silicones (SR), epoxies (ER), and urethanes (UR), the shorter name “Parylene” was eventually adopted. Type XY Conformal Coating Application Type XY conformal coating is applied through a... Read More >>
