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.

How To Create Your Own Internal Conformal Coating Test Standard

Posted by Chris Palin on Jun 19, 2017 11:00:00 AM

How do you select and test a conformal coating that is right for your specific application? Or maybe you would like to create your own test specification due to any special characteristics of your device’s operating environment? Or depending on your geographical location, you may also be required to use a different testing specification that is dictated by local authorities.

A widely used method to create an internal specification, is to simply select a conformal coating material that meets an existing specification standard. Such standard could be MIL-I-46058C or IEC-60664. However, you must be careful to ensure that the existing standard that you choose, does indeed meet 100% of your requirements. In such cases, you may have to specify test methods from other existing standards.
