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 >>
Repairing Parylene Delamination
Applied as a conformal coating through a unique chemical vapor deposition (CVD) process, Parylene conformal coatings provide an ultra-thin, pinhole-free barrier protection for a wide range of components. With appropriate pre-treatment, CVD penetrates deep within substrate surfaces, rather than merely attaching to substrate exteriors. Ultra-thin protection negates operational dysfunction caused by excessive coating mass or... Read More >>
A Guide to Parylene Service Temperatures
A specialized chemical vapor deposition (CVD) process adheres Parylene conformal coatings to substrates. CVD uniformly encapsulates all exposed substrate surfaces as a gaseous monomer; completely eliminating wet coatings’ liquid phase and need for post-deposition curing. Synthesizing in-process, CVD polymerization requires careful monitoring of temperature levels throughout. Beneficial thermal properties of Parylene protective coatings include reliable...

Benefits of Conformal Coatings for LEDs
LEDs are often subjected to harsh environments. To ensure that they perform reliably long term in these conditions, LEDs often rely on conformal coatings. Below are the three coatings commonly considered to protect LEDs: Parylenes: Parylenes are often selected due to their ultra-thin, optically clear nature and resistance to moisture and chemicals. Designed for harsh... Read More >>
Conformal Coating for Agricultural Lighting
Used for food production, indoor gardening and hydroponics and horticulture, grow lights have both industrial and consumer applications. Because total illumination intensity diminishes with distance from the point source (grow lightbulbs), production efficiency is enhanced by: The objective is equal lighting, with the entire range of generated illumination shining on plants. Where direct light is... Read More >>
Can Parylene be used as a Standalone Enclosure?
Parylene polymer conformal films are recognized for their wide array of advantageous functional traits when it comes to coating printed circuit boards (PCBs) and similar electronics. These films offer valuable properties like biocompatibility, resistance to chemicals and solvents, reliable dielectric and insulation characteristics, and ultra-thin, pinhole-free film thicknesses ranging from 1 to 50 μm. Furthermore,... Read More >>
Types of Parylene
Applied in a gaseous form to component surfaces through a chemical vapor deposition (CVD) process, Parylene (Poly-para-xylylene) films protect printed circuit boards (PCBs) and similar electrical assemblies. Gaseous CVD application supports efficient coating of complex component surfaces characterized by crevices, exposed internal areas, or sharp edges. Depending on the specific use, Parylene conformal coatings exhibit... Read More >>
When to Use Conformal Coating Removal Services
If necessary, it is possible to remove unwanted conformal coatings from PCBs. The process can often be accomplished by either the assembly’s original equipment manufacturer (OEM) or an end-user, but the capability to do so does not always exist. For these parties, removing the coating may be beyond the purview of their experience with conformal... Read More >>
