How to Remove Conformal Coatings

Posted by Sean Horn on Fri, Aug 18, 2017 @ 07:30 AM

Appropriately selected and applied, conformal coatings provide essential working protection for printed circuit boards (PCBs). However, removal of conformal coatings is necessary if the wrong coating material is selected relative to the PCB’s functional requirements, inadequately supporting its operating environment. Poor coating application can trigger failure mechanisms within the assembly, also calling for its removal and re-application.

Conformal Coating for PCB's

Posted by Sean Horn on Fri, Jul 21, 2017 @ 07:47 AM

Printed circuit boards (PCBs) electrically connect and power all but the simplest electronic products.  To function as designed, PCBs and their components – capacitors, resistors, etc. – require protection against operating problems caused by corrosive liquids, dust, physical shock, temperature extremes and, in the case of medical implants, bodily fluids.  Conformal coatings are applied over PCBs to safeguard mechanisms and maintain functionality.

Which Conformal Coating Is Right for Me?

Posted by Sean Horn on Fri, May 19, 2017 @ 07:30 AM

          The value of polymeric conformal coatings for protecting printed circuit boards (PCBs) from functional retardants like dust, corrosion, moisture, and temperature fluctuations has been well-documented.  Conforming to the physical configurations of the exposed face of the PCB, conformal coating:

Parylene and Silicone Conformal Coatings:  A Comparison

Posted by Sean Horn on Fri, Jun 24, 2016 @ 07:30 AM

One liquid coating type that rivals the use of parylene is silicone conformal coating (Type SR), which cures rapidly, is reliably dielectric and displays exceptional stability across a wide temperature range.  These properties make it parylene’s chief performance competitor, for many purposes.  Further comparison delineates their benefits and disadvantages relative to each other.

Silicone Conformal Coating vs Parylene

Posted by Sean Horn on Fri, Aug 07, 2015 @ 09:46 AM

Silicone and Parylene conformal coatings are a lot like humans and dogs. At first glance, we are very different from our canine friends. However, we have a lot in common -- noses, two eyes, hearts, dreams. In fact, we share 84 percent of our DNA with Rover (or Spot). So too with the two coatings. While both have some functional differences -- which we'll explore here -- they also have an important similarity. Parylene and Silicone are both some of the best choices for conformal coatings of your company's products.

Best Conformal Coating for Humid Environments

Posted by Sean Horn on Fri, Apr 10, 2015 @ 08:43 AM

Just about every major type of conformal coating provides protection against moisture. If you get a printed circuit board coated with epoxy, acrylic, urethane, silicone or parylene wet, typically all that you have to do is wipe it off. Environments with high humidity pose a different set of challenges. Because moisture is omnipresent in humid environments, the conformal coating doesn't just have to resist water ingress. It also needs to completely seal the coated item. Given this additional requirement, the best choice will usually be either silicone or parylene.

Conformal Coatings for LED Applications

Posted by Sean Horn on Wed, Oct 30, 2013 @ 07:58 AM

From front to back, LEDs are improved by conformal coatings. Whether the coating is improving the LED's color accuracy, protecting it from damage or keeping the electronics functioning well, conformal coating of LED electronics extends the suitability of LED technology. Here are the top six ways that conformal coating and LEDs go well together

Parylene Alternatives

Posted by Sean Horn on Fri, Jan 18, 2013 @ 08:43 AM

Parylene conformal coating is a very robust coating, but sometimes it is not the right fit for a customer’s application for one reason or another.  The entire conformal coating process is based on first identifying the standards to be used and customer’s protection desired.  It would therefore only make sense that there are alternatives to parylene for different conformal coating demands.
