Unpacking the Rising Popularity of LED Curable Conformal Coatings

Posted by Dan Griffin on Dec 7, 2022 6:28:13 PM

The transition to LED curable conformal coatings is beginning to build momentum, beginning as a slow evolution and developing into a revolution of sorts. The driving forces behind this include: 

  • Improved processing equipment designs and availability 
  • Aging or outdated application equipment replacements 
  • Increasing range of LED curables commercially available or in development 
  • Rising labor, equipment, and energy costs  

If you and your organization are faced with aging equipment and higher costs, there isn't a better time to consider the potential advantages of LED curable conformal coatings

Get the Best Results When Manual Brushing Conformal Coatings

Posted by Vlad David on Nov 9, 2022 10:54:30 AM

Manual brushing is just one of many methods commonly used for applying conformal coating materials to PCBs and other components. It is a hand-applied method that requires little investment into automation or equipment. With practice, it can be one of the simplest methods available, especially for small-batch production or isolated applications.

Complete Guide to Viscosity Part 2: Measurements and Devices Explained

Posted by Vlad David on Jul 7, 2022 12:15:49 PM

This blog is the second installment in our two-part series on viscosity (with special consideration on adhesives and coatings).

In our previous viscosity blog, we discussed the properties of viscosity and how viscosity can be affected by temperature, the addition of dilution or thinning agents, and other similar factors.

The Evolution of UV Curable Conformal Coatings

Posted by Chase Corp Editor on Mar 8, 2022 10:59:29 AM

Durable Protection for Demanding Automotive Requirements

HumiSeal chemists have been designing state-of-the-art conformal coatings for nearly 70 years, first producing UV curable coatings more than two decades ago. At that time, UV curable technology was considered the next generation of coatings, mainly due to its advantages; including:

Protect Yourself Against Counterfeit Conformal Coatings

Posted by Peter Manning on Feb 21, 2022 11:48:04 AM

Counterfeits exist. Our industry is no exception. We’ve pointed out counterfeit conformal coatings on two separate occasions, but it is time to do so again. Unlike most electronics components, damage attributed to counterfeit conformal coatings is often unreported as it can be challenging to tell the difference between counterfeit brands and the original coating. The best way to protect yourself against this is to purchase directly from HumiSeal or one of our authorized channel providers.

Complete Guide to Viscosity: Part 1

Posted by Vlad David on Jan 18, 2022 11:15:00 AM

This is the first in a short series on material viscosity, in which we will review what it is and how to measure it. We will start with the definition of viscosity. Viscosity is the internal friction of moving fluid and a measurement of the resistance of a fluid deformed by shear stress. It is measured in centiPoise. The lower the number, the less viscous the material, as can be seen by this comparison chart: starting with water at 1 cPs and ending with honey at anywhere between 2,000 – 10,000 cPs.

Masking Before Parylene Conformal Coating

Posted by Dan Griffin on Oct 28, 2021 11:00:00 AM

Conformal coating with parylene is a very different process compared to coating with traditional solvent-borne or UV curable materials. Parylene coating has some advantages including

  • a very thin application profile,
  • uniform and complete surface coverage, and
  • generally excellent protection and minimal outgassing potential.

On the other hand, parylene coating also presents unique challenges such as

  • a significant investment in complex equipment,
  • batch processes that limit productivity and increases costs, and
  • the user’s inability to selectively control where the coating is applied.

It is this final challenge that we will concern ourselves with within the following discussion.

b* Stability Explained: Nobody Wants a Yellow LCD Display

Posted by Dan Griffin on Sep 23, 2021 9:00:00 AM

Most anyone over the age of 30 has probably seen Back to the Future and remembers Marty McFly. One line of Marty’s that inexorably drew him into ill-advised actions was the classic “Nobody calls me yellow.” Nothing good comes from yellow, and this turns out to be just as applicable in LCD screen manufacture as it was in the movie.
