Unpacking the Rising Popularity of LED Curable Conformal Coatings

Written by Dan Griffin | Dec 7, 2022 11:28:13 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  • Aging or outdated application equipment replacements 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

 

Benefits of LED Curable Conformal Coatings 

There are countless advantages to choosing LED curable coatings, including:

  • Processed on the same commercial spray equipment as traditional conformal coatings (Saves $$) 
  • less need for expensive curing enclosures (Saves $$) 
  • consistent and repeatable cure 
  • lower energy requirements (Saves $$) 
  • little or no hazardous wavelengths generated 
  • less heat generation for sensitive components 
  • longer bulb life and lower maintenance costs (Saves $$)
     

Common Applications for LED Curable Conformal Coatings

LED curable coatings are suitable for nearly all conventional conformal coatings applications. Their lower energy and maintenance requirements combined with short cycle times make them especially valuable in certain areas including 

  • Automotive PCBs due to their high volumes and energy requirements  
  • White goods such as refrigerators, washers, and dryers 
  • HVAC control boards 
  • Electronic vehicle applications including power and safety controls and autonomous driving devices
