What is UV radiation?

Ultra-violet radiation forms part of the electromagnetic spectrum and is invisible to the naked eye. The wave length of UV radiation varies from 100-400nm, finishing in the blue portion of visible light.

In terms of energy output, the shorter the wavelength of the UV radiation the higher the energy of the light. These energy levels can be subdivided into 4 specific regions:

  • UVA-Radiation (400-315nm)
  • UVB-Radiation (315-280nm)
  • UVC-Radiation (280-200nm)
  • VUV-Radiation (200-100nm)

SCH Technologies use UV light technology in curing conformal coatings in both their coating services and in their UV conformal coating conveyors.

About Dr Lee Hitchens

Dr Hitchens has been working in the electronics industry and the area of conformal coatings for over 25 years in various areas including sales and technical support. He has also been training people for almost the same amount of time in all areas of conformal coating whether that is materials & equipment selection, process development or troubleshooting to help them solve their particular problem. Recently, he decided that the industry needed a specific place where all of the useful knowledge on conformal coatings could be collated for users to find easily and use in their own production process. So, Nexus was born and he began the Nexus eBook project.
