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:

Click on each to examine individually for details or click conformal coating application techniques for an overview.

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.

Where are conformal coatings used?

Conformal coatings are being used as protection in ever increasing electronic applications across a wide range of market sectors.

Due to the fact conformal coatings provide several key benefits including moisture and insulation properties, chemical resistance and particulate protection, this means they are used anywhere there is a need for a higher reliability than that which is achieved without the coating.

However, it is possible to identify traditional and emerging sectors where conformal coatings are applied.

Book your place on the Nexus Webinar: Conformal Coating Guide to Design, Application & Reliability which will be held on the 12th November 2012

The Nexus webinar: Conformal Coating Guide to Design, Application & Reliability will be held on the 12th November. 

Conformal coating may be a new process to many people and its important to have a good grounding in the fundamentals before embarking on the use of coatings. An incorrect choice at the design stage can add significant cost to the product without the desired benefits. Correct selection of components and application techniques can significantly reduce cost by reducing or eliminating masking steps. A key step during design is to assess the effective reliability prior to going into full production.

Topics will include:

Why conformal coating is necessary
Types of material and their benefits
Design engineers check list
Coating application methods
Testing product reliability

Application Methods, Materials for Field Reliability
Monday 10th December

There are different Conformal Coating application methods and materials to coat a board assembly. The product type and its application are the key factors in the decision process but do you have the onsite knowledge? You should also look at the onsite or subcontract services options, depending on the product and the requirements, and it may make sense to contract it out for technical reasons. Assessment of the effectiveness of the selected conformal coating is key to long term reliability but how is this assessed and what are the criteria?

Topics will include:

Service environment and coating selection
Application with dip, spray, vacuum (parylene) & manual methods
Onsite or contract service what are the options?
What are the true cost factors to consider?
Reliability testing of coatings and products
