What can be Coated: Conformal Coatings and Parylene Compared

Posted by Sean Horn on Fri, Mar 23, 2018 @ 08:02 AM

Conformal coatings are used to protect printed circuit boards (PCBs) from dust, humidity/moisture, mildew/mold, temperature extremes, and other elements whose prolonged contact might interfere with assembly function. Coatings also enhance electrical clearance-tolerance, while safeguarding PCB components from contamination (particulate or otherwise), corrosive materials, and mechanical stress.

Brush Application of Conformal Coating

Posted by Sean Horn on Fri, Mar 02, 2018 @ 08:00 AM

Conformal coatings’ functional value stems from their ability to safeguard printed circuit boards (PCBs) and similar electronics from external threats to their performance. Composed of acrylic, epoxy, silicone and urethane polymer resin, coatings also provide layers of insulative protection. These liquid coatings are applied to PCBs by wet methods, primarily by brush, dipping (component immersion) or automated/manual spraying.

Aerospace Conformal Coatings

Posted by Sean Horn on Fri, Feb 09, 2018 @ 08:05 AM

Conformal coatings composed of acrylic, silicone and parylene polymer materials are valuable for a wide range of aerospace applications, which can push technologies to their limits. Applied to printed circuit boards (PCBs) and related electrical assemblies, conformal coatings maintain device performance through difficult operational conditions. The presence of atmospheric variation, chemicals, humidity, mobile ion permeation, moisture, temperature fluctuation, or excessive vibration can generate:

Conformal Coating Applications: Liquid vs Parylene

Posted by Sean Horn on Fri, Jan 19, 2018 @ 07:10 AM

Conformal coating of an object occurs when an appropriate coating material is applied on-top and around an underlying substrate, to protect it from such environmental and performance concerns as chemical incursion and excess moisture. Liquid organic polymer conformal coatings – acrylic, epoxy, silicone and urethane – prevent:
