Electric Vehicles: Polymers for Performance, Reliability, & Protection

Posted by Dan Griffin on Jul 30, 2020 1:00:00 PM

Adoption of plug in -electric vehicles (EVs) has been slower than many expected, but there is little question the next few years will see adoption accelerate. Your hypersensitive dog will have to find new visitors to harass when your delivery drivers arrive without notice, driving to your door silently in all-electric commercial vans. Many of your favorite suppliers and stores have already ordered these vehicles. Game-changing battery and charging developments are eliminating range anxiety, and autonomous driving controls and safety innovations are in the final stages of building our trust.

Protective Coatings and Polymers for Hydrogen Fuel Cell Electronics

Posted by Jacek Knop on Jun 30, 2020 2:45:04 PM

Modern hydrogen fuel cell technologies require ever more sophisticated and reliable electronic control systems to assure both safety and longevity. Hydrogen fuel cells are gaining in popularity in critical industries including automotive, aerospace, ocean transportation, military, and power microgrid systems among others. Protection of printed circuit boards and their components from physical, chemical, and thermal damage is essential to produce robust and reliable fuel cell systems for demanding applications.

Understanding the Importance of the Moisture Vapor Transmission Rate of Conformal Coatings

Posted by Dan Griffin on Mar 25, 2020 10:00:00 AM

A critical function of conformal coatings is to protect PCBs and electronics from damage caused by moisture and humidity. In this discussion, we will attempt to answer some of the more common questions we often hear regarding the level of protection you can expect from a conformal coating.

Are conformal coatings waterproof?

The above is probably the most common question and most misunderstood subject in the area of PCB protection

The Potential Cost of NOT Conformal Coating Your PCB

Posted by Dan Griffin on Jan 23, 2020 10:00:00 AM

The PCB industry continues to evolve with ever increasing demands for efficiency and manufacturing cost reductions. From the design phase onward, suppliers and contract manufacturers are being asked by their OEM overlords for increased performance at lower and lower costs. An obvious potential source for cost reduction is the use of alternative cheaper raw materials or their elimination where possible. At some point in the discussion, it is sometimes asked,  “Why don’t we just eliminate the conformal coating?” or "Are conformal coatings necessary".

Thinners for Conformal Coatings: The Basics of What, When, and How

Posted by Dan Griffin on Oct 31, 2019 10:30:00 AM

You have completed your search for an ideal conformal coating chemistry, one that will provide your PCBs the protection and reliability demanded by your industry and customers. After all that work, you probably assume your job is finished. Our apologies for being the bearer of bad news: There is still work to be done. In this basic presentation and discussion, we will talk about the proper choice and implementation of thinners for your coating. In many cases, a mistake in thinner can harm or even completely negate the protective properties of your conformal coating when applied to your PCB.
