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  • Aging or outdated application equipment replacements 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

How to Calculate the Cost of Conformal Coating on a PCB?

Posted by Dan Griffin on Apr 16, 2020 11:00:00 AM

One of the most basic and common questions we at HumiSeal® are asked by both existing and potential new customers is,

“How much does it cost to conformally coat my printed circuit boards?”

Since conformal coatings are usually sold in liquid form by the liter or gallon, it is necessary to go through a fairly basic calculation that we will present here.

The simplest and most common way to evaluate cost is by determining the cost in dollars of coating per PCB.

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".

Protective Gels: The Next Level of Protection for Your PCBs

Posted by Dan Griffin on Dec 16, 2019 9:57:33 AM

Conformal coating of printed circuit boards (PCBs) has resulted in a steady evolution in performance and protection for modern electronics. It has allowed for lightweight and reliable controls in industries such as automotive and aerospace among others. This has brought about the possibility of increased length of warranties as well as fewer failures and claims. Nevertheless, original equipment manufacturers (OEMs) and consumers continue to raise their standards and expectations for longevity and reliability to levels unimagined just 10 years ago. In the automotive industry, as an example, thermal cycling testing might have involved as few as 10 or 50 cycles in the recent past. That standard is now often 500 or even 1000 cycles with no apparent ending in sight.

So what do I do when conformal coating is not enough?
