What application methods are available for applying conformal coating?

 

Conformal coatings can be applied to printed circuit boards (PCBs) in the production process environment in many different ways.

Listed below are the common methods of applying conformal coating materials:

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.

What are my options for conformal coating application methods?

This is a question I am asked time and again.

Of course most people know of the selective robot and how it applies conformal coating.

However, there are many different application methods available for both liquid conformal coatings and Parylene and listed below are the common techniques:

Note, each of the various methods has different strengths and weaknesses.

However, each of these application methods should be considered in relation to the holistic approach to conformal coating processing 

What is the holistic approach to conformal coating?

The holistic approach states that you should consider the conformal coating material, the application process and the circuit board together and not as three separate entities.

I consider this approach the most fundamental issue and crucial factor in all of conformal coating processing.

Ironically, it is ignored on a regular basis.

In fact, I find that the failure to apply the holistic approach at the beginning of the conformal coating selection process is normally the root cause of many conformal coating problems.
