Best Electronics Coatings

Posted by Sean Horn on Fri, Nov 17, 2017 @ 08:01 AM

Available in five basic material types, conformal coatings can be readily adapted as protective, insulating films for electronics. However, there can be some confusion about which type is best-suited for a specific use. Clearly defining the performance parameters for the component[s] to-be-coated helps coordinate the conformal film material with a unit’s functional requirements. Accurate assessment of environmental conditions like anticipated levels of corrosion, contact with foreign particulates, expected concentrations of moisture/salt spray, temperature fluctuations and vibrational range determine which coating type is best-suited to your electronics’ applications. Without appropriate protection, printed circuit boards (PCBs) and similar electronics will not survive harsh environments, and malfunction.

Is Parylene a Conformal Coating?

Posted by Sean Horn on Fri, Nov 10, 2017 @ 08:06 AM

If, for some reason, you are told parylene is NOT a conformal coating, simply because it has no liquid phase of application, just walk away. And maybe have yourself a good laugh. For, as you may already know, parylene has repeatedly proven itself to be the most definitive of conformal coatings, for a variety of reasons, including:

4 Aerospace Applications of Parylene

Posted by Sean Horn on Fri, Nov 03, 2017 @ 07:49 AM

Superior to liquid coatings like acrylic, epoxy, silicone and urethane, parylene conformal films offer unparalleled protection for aerospace printed circuit boards (PCBs) and related electronic assemblies. Their complete encapsulation conforms entirely to all device surfaces – flat, round, creviced or edged, while adding almost no weight to the covered device.

Selecting a Parylene Conformal Coating Service Provider

Posted by Sean Horn on Fri, Oct 27, 2017 @ 08:04 AM

Selecting the best material/application method for your coating assignment prolongs assembly service-life and promotes optimal performance. The conformal coating industry is highly competitive, with competent providers available throughout the country. Compared to liquid resin coating materials – acrylic, epoxy, silicone and urethane – the polymer parylene generates superior conformal coating, but is more complex and expensive.

How to Source Conformal Coating Removal Services

Posted by Sean Horn on Fri, Oct 20, 2017 @ 08:03 AM

Conformal coatings provide reliable working security for PCBs. However, poor coating application or selection of the wrong coating material can cause assembly malfunction. In other cases, poorly manufactured PCBS may need component repair/replacement. When these problems arise, coating removal is necessary.

Three Things to Look for in Conformal Coating Services

Posted by Sean Horn on Fri, Oct 06, 2017 @ 08:15 AM

Printed circuit boards (PCBs) interconnect microchips and similar electronic components etched or laminated onto flat fiberglass/plastic panels. A variety of conformal coatings – liquid resins of acrylic. epoxy, silicone or urethane and chemically inert parylene -- assure proper insulation for PCBs. Such environmental conditions as contamination from debris, humidity within the unit, solvent incursion or the impact of human handling are minimized by conformal protection, reducing performance degradation while prolonging assembly life.

Conformal Coating Quality Standards

Posted by Sean Horn on Fri, Sep 15, 2017 @ 08:18 AM

Conformal coatings differ in their material-specific performance properties as protective films for electronic assemblies. Knowing the operational characteristics of various coating-types and their functional association with assembly components supports successful film application. Issues that confound conformal coating selection and application result from potential post-application problems like:
