Conformal coatings can be applied to printed circuit boards (PCBs) in the production process environment in many different ways including spraying selectively, batch spraying and dipping.

The holistic approach to conformal coating application methods 

It is possible to split the different application methods and their suitability in many different ways including:

  • Compatibility with the conformal coating material
  • Design of the circuit board
  • Suitability to low, medium and high volume
  • Manual versus automatic process
  • Type of method of application
  • Level of control required

Each of the various coating methods has different advantages and disadvantages.

This relates to the holistic approach to conformal coating processing. It states that you should consider the conformal coating material itself, the application process and the circuit board together and not as three separate entities.

However, when considering the application methods it is possible to make some assumptions that help in selection.

China Nexus Workshop Topic: Encapsulation and Potting – Where do they fit in compared to conformal coatings?

Nexus are to hold a FREE conformal coating workshop in the Diamond SCH coating facility in Shenzhen China on the 17th October 2012.

Topics include Encapsulation and Potting – Where do they fit in compared to conformal coatings? This presentation looks at the role of encapsulation and potting relative to conformal coatings and discusses where the boundaries lie in using one material reliably compared to the next.

For example, if you want to waterproof a PCB what coating, encapsulant or potting material should you use? Watch this presentation and find out more.

This One-day workshop will be held at the Diamond SCH Conformal Coating Facility. The address is 3rd Floor, A5 Building, Tianrui Industrial Park, Fuyuan Road1, FuYong Town, Baoan District, Shenzhen, China.
