Cleaning Methods for Conformal Coating
Cleaning the substrate is an essential element of preparation for conformal coating, and here are several key reasons why: Although taking the steps to assure that substrate surfaces are clean increases production time and expense, the consequences of applying conformal coatings to contaminated components is far costlier and more time-consuming in the end. In addition,... Read More >>
Parylene’s Optical Properties and Performance
Parylene is a reliable, protective, conformal film that safeguards printed circuit boards (PCBs), similar electronic assemblies and other products. Parylene generates advantageous optical properties for a wide range of uses, including artwork/museum artifacts, cameras/sensors, computer touchscreens, healthcare/medical devices, light-emitting diode systems (LEDs), lenses and optoelectronic components. It should be noted that while the thinnest Parylene... Read More >>
Parylene Conformal Coatings and UV Light
Parylene has numerous outdoor applications. However, a major drawback of most Parylene types is limited resistance to direct contact with UV radiation. Daylight is the most common source of UV light. Prolonged exposure to its high energy radiation can cause objects extensive surface damage and lead to eventual malfunction of coated products. This is a... Read More >>
UV-Cure Touchup and Parylene Coating
UV curing, a photochemical process utilized to preserve conformal coatings, adhesives and inks, offers a range of enhanced properties compared to traditional curing methods. By exposing coatings or other substances to intense UV light for drying (curing), this technique delivers immediate results, boosting production speed and minimizing the need for setup and cleanup procedures. Reduced... Read More >>
What Types of Materials can be Parylene Coated?
A large number of substrate surfaces can be coated with Parylene. Below is a sample list of several industrial applications that can be coated with Parylene conformal coatings. With Parylene chemical vapor deposition (CVD), it is possible to obtain stress-free and defect-free conformal coatings on almost all types of materials. Sensors used in the automotive... Read More >>

Conformal coatings are applied to a wide array of products for various industries such as aerospace, automotive, biomedical, consumer goods, and military applications. These coatings aim to create a protective film that enhances the ease of use, functionality and longevity of the devices across different environments. Liquid Teflon™ (PTFE) and Parylene are two widely used... Read More >>
Ruggedizing COTS Electronics with Parylene
Parylene Coatings and COTS Electronics Because each conformal coating material has its unique strengths, selecting the right one for a particular application often depends on the specific environment where the product is to be used. Parylene conformal coatings provide dependable protection for printed circuit boards (PCBs) and related electronic assemblies. They safeguard components from contaminants,... Read More >>
The Impact of Temperature on Parylene Adhesion
Basic Thermal Properties of Parylene Conformal Coatings Vapor deposited Parylene combines high thermal stability with a low dielectric constant, minimal moisture absorption and other advantageous properties which sustain its adhesion to substrate surfaces. Among the most beneficial of Parylenes’ thermal properties is their ability to function at an exceptional range of temperatures. Depending on the... Read More >>
Mastering the Parylene Coating Process
While the Parylene deposition process is relatively straightforward, its implementation can pose challenges, especially in controlling coating thickness and ensuring a successful coating cycle. Because coating type and required surface thickness vary according to substrate material and coating project, deposition rates fluctuate. Processing times can vary from under an hour to over 24 hours, with a deposition rate of... Read More >>
How Easy is Parylene to Rework?
When it comes to reworking, Parylene’s strengths are also its biggest drawbacks. In addition to its ability to conformally coat substrates, it is also, by design, very challenging to remove. However, a good planning strategy before coating can help to reduce the need for Parylene rework. The Parylene Challenge Parylene dimer is deposited as a... Read More >>
