Six Reasons to use Acrylic conformal coating to protect your circuit boards

  1. Acrylic conformal coating materials provide a protective non conductive dielectric layer that is applied onto the printed circuit board assembly to protect the electronic assembly from damage due to moisture.
  2. They reduce fungus growth on the circuit board in the long-term.
  3. They prevent dust, contamination and any foreign debris falling onto the unprotected surface. This, stops corrosion occurring in harsh or extreme environments.
  4. Conformal coating also can prevent damage from rough handling during installation and the lifetime of the product
  5. There is some evidence that the conformal coating can aid in the reduction of mechanical and thermal stresses on the components and circuit board itself during service.
  6. The coating can help to increase the dielectric strength between conductors enabling the design of the PCB to be more compact and small.

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.
