Get on the Right Wavelength with LED Curable Conformal Coatings

Posted by Dan Griffin on Jun 27, 2019 10:32:28 AM

The evolution of conformal coatings for protection of PCBs and electronics has accelerated over the past few years. One development in particular has increased in popularity due to a promising array of advantages over its predecessors. These are LED Curable Coatings.

A partial list of existing technologies for conformal coatings would include:

  • acrylics (both solvent and water-borne)
  • solvent-borne polyurethanes
  • silicone-based polymers
  • synthetic rubber (solvent-borne)
  • Parylene technology
  • UV-curable acrylated urethanes (arc and microwave bulb source)

and most recently . . .

Why Does LED Technology Require Conformal Coating?

Posted by Chris Palin on Jul 19, 2017 9:39:16 AM

ENERGY STAR, The United States Environmental Protection Agency program that provides certification to buildings and consumer products which meet certain standards of energy efficiency, defines what a LED light is.

LEDs, or light-emitting diodes, are semiconductor devices that produce visible light when an electrical current passed through them. LEDs are a type of Solid State Lighting (SSL), as are organic light–emitting diodes (OLEDs) and light–emitting polymers (LEPs). 

Also states: Thermal management is probably the single most important factor in the successful performance of a LED product over its lifetime because the higher the temperature at which the LEDs are operated, the more quickly the light will degrade, and the shorter the useful life will be.
