Why Does LED Technology Require Conformal Coating?

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),...

An Effortless Approach to Eliminate Bubbles in Conformal Coating Through Solvent Type and Product Selection

Hello Again!  The last time we discussed bubbles in conformal coating, I wrote how to resolve process related root causes.  There are other simple ways to reduce the amount of bubbles:

  • by varying the types of solvents used in a product
  • by using a product that contains a surface tension modifier, hence increasing the rate at which bubbles burst.

If you recall, most of the bubbles are...
