Best Electronics Coatings
Available in five basic material types, conformal coatings serve as adaptable protective and insulating films for electronics. However, selecting the most suitable type can be difficult. Clearly defining the performance parameters of the components to be coated is crucial to determine the optimal conformal film material that aligns with the unit’s functional needs. An accurate...

Conformal Coating Removal Standards
If problems in a conformal coating defy reliable repair, coating removal may be the only solution. Removing conformal coating from PCBs requires matching removal methodology with coating type and the component’s function. A variety of factors – bubbles/voids, coating thickness, component failure, inadequate masking, poor adhesion, surface finish, among many others – can necessitate coating removal.... Read More >>
Is Parylene Coating Biocompatible?
Parylene is one of the most biocompatible conformal coatings currently available. Its chemical properties make it a natural for use in medical and biological applications. In addition, some of its general benefits also make it particularly valuable in healthcare applications. Finally, Parylene also holds a stringent USP Class VI biocompatibility certification. Parylene’s Chemistry and Capabilities... Read More >>
Best Conformal Coating for Humid Environments
Liquid conformal coatings such as epoxy resins (ER), acrylic resin (AR), polyurethane (UR) and silicones (SR) as well as Parylene conformal coatings (XY) are well known for protecting printed circuit boards (PCBs) against moisture. In the case of high-humidity environments; however, a different set of challenges can arise. Since moisture is omnipresent in a humid... Read More >>
All About Conformal Coatings
Conformal coatings insulate printed circuit boards (PCBs) and similar electronics; their protection increases devices’ tolerance to harsh environments. The result is undisturbed functionality through a range of frequently harsh operating environments and performance conditions. Conformal coatings are used to protect applications in the aerospace/defense, automotive, consumer and medical device industries. There are five basic types... Read More >>
Silicone vs. Urethane Conformal Coating
Silicone and urethane stand out as prevalent conformal coating types due to their protective attributes. The superiority between the two coatings hinges on your specific application. Below is an exploration of the advantages and disadvantages of each type. Silicone Conformal Coating Benefits Most common silicone coatings have continuous operating temperature ratings of 200ºC. This is... Read More >>
Conformal Coating vs. Potting
There are two common methods for circuit board protection, conformal coating and potting. Depending on the project, the use of one of these two options typically provides sufficient protection to a circuit board. What is Conformal Coating? Conformal coating is a protective, nonconductive dielectric layer that is applied onto the printed circuit board assembly to protect... Read More >>
The Conformal Coating Removal Process
Removing unwanted conformal coating from a PCB can range from a straightforward task to a challenging undertaking. The ease or difficulty of the process is dictated by the type of coating that needs removal, its location on the board and the components present. Identify the coating to be removed from the assembly first. Once determined,... Read More >>
Why use a Conformal Coating Drying Cabinet?
Various pieces of conformal coating equipment serve distinct functions, with drying cabinets being no exception. Drying cabinets play a crucial role in the process, extracting air from around assemblies, securing them in place during curing, and shielding them from potential damage. Drying cabinets are mainly used to extract air from around the assemblies to aid... Read More >>
Conformal Coating Quality Standards
Conformal coatings vary in their material-specific properties when used as protective films for electronic assemblies. Understanding the operational traits of different coating types and their interaction with assembly components is crucial for effective film application. Challenges in selecting and applying conformal coatings stem from possible post-application issues such as: Stringent professional standards and specifications are... Read More >>
