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 >>
Liquid Teflon™ vs. Parylene
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 >>
Parylene for Medical Sensors
Many medical devices rely on sensors to detect and measure conditions affecting patient health. These sensors often record and transmit data on physical properties like heartbeat, blood pressure, breath rate, temperature and more to medical personnel and technology, enabling continuous physiological monitoring of health-specific disorders and improving the quality of diagnosis and treatment. Sensors are... Read More >>
Conformal Coating Boots vs. Tape: Making the Right Choice
Masking tapes and boots serve to shield components for specific masking purposes. Optimal masking protection hinges on selecting between the two options. It is imperative to uphold conductivity at all times. Moreover, operational variables such as the assembly’s production volume, the surface geometry of the component/assembly, and the type of coating on the assembly substrate... Read More >>
What is a Good Thickness for Acrylic Conformal Coating?
Acrylic conformal coatings (type AR), such as MG Chemicals 419C and HumiSeal® 1B31, are a very popular conformal coating choice. They are used primarily for moisture protection on printed circuit boards. Often, they are utilized because of their easy-to-use nature. As a result of this, acrylic conformal coating is frequently applied as a DIY project.... Read More >>
