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 >>
Parylene vs Acrylic Conformal Coatings
Parylene and acrylic resins serve as conformal coatings, yet their similarities are limited. Due to their distinct properties, each possesses unique uses and capabilities. Application Acrylic conformal coatings, a type of liquid conformal coating, can be applied in four ways: by spray, dip, brush or robotics. The chosen method depends on several factors, such as...

Parylene and Wearable Devices
Wearables are no longer an emerging technology — they are here. Whether a wearable is a medical device like an insulin pump, a smart watch or even a finely woven piece of smart fabric, they all have one basic fact in common. All of them contain technologies that need protection from the outside world, and... Read More >>
Benefits of Parylene Coatings for Electronics
Parylene conformal coatings are some of the best protection options available for printed circuit boards, multi-layer assemblies and other electronics. The coatings are applied through a vapor phase deposition (VPD) process that transforms the solid Parylene raw material, known as dimer, into a gas, enabling complete coverage of the substrate’s surface including deep penetration into...

Properties of Acrylic Conformal Coating
Exceptionally user-friendly, liquid acrylic resin (AR) conformal coatings protect printed circuit boards (PCBs) and similar electronics from corrosion, dirt/dust, fungus, moisture and thermal shock. AR’s ease of application contributes to its status as the most frequently used conformal material. Liquid Application Methods for AR The primary means of AR liquid application are brush, dip (immersion)... Read More >>
Low Outgassing Conformal Coatings
Hermeticity and Outgassing In an ideal hermetic system that is under vacuum and completely sealed, unless gas is injected, entry of gasses from the surrounding environment is restricted. However, in reality hermetic systems can still have some leakage through their sealings and via outgassing of internal components. Outgassing is the desorption of gases/vapors from the...

Differences between Parylene and Acrylic Conformal Coating
Parylene and acrylic conformal coatings represent two extremes of the types of compounds that can be used to coat printed circuit boards, sensors or an array other devices. While acrylic is popular and inexpensive, Parylene offers some of the best performance of any coating compound. Understanding AR Acrylic resin (AR) is the most commonly used... Read More >>
