The critical areas of designing for conformal coating
Are these phrases familiar on the conformal coating production line to you? “Who designed this process?”, “This is impossible. We can’t meet their requirements”, “How did they decide to coat this board this way?”
It is tempting to consider one of these parts in isolation.
However, this could be a mistake.
After all, the wrong choice can be devastating to the conformal coating production process as a whole and even worse, the reliability of your product.
I feel that to identify the best conformal coating material and application process there are several key factors that you need to consider that, if you are lucky, will add up to at least one sensible process choice.
Factors to be considered include:
Temperature operating range
International, customer or National Standards
Environmental considerations of the circuit board
Requirement to rework the conformal coating
Conformal coating material type
Application process considerations
Curing the conformal coating
National, State, Regional Legislation and Insurance
Choosing a conformal coating process is a complicated and involved process usually balancing a number of trade-offs and compromises. This is because of three major parts of the complete process that can offer different options and create difficult choices.
These parts are:
The Conformal Coating Material Requirements
The Application Method Selected
The Circuit Board Design
When you consider these three points you have to balance them to create the best compromise solution that suits your requirements. This is the Holistic Approach to conformal coating.
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 Understanding Liquid Conformal Coating Materials & their Selection. This presentation will look at How to select a conformal coating, the various coating material properties, your options for selecting the coating and what can happen when you get it wrong.
Want to choose the right conformal coating for the project and protect the circuit board correctly? Don’t miss 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.
Each How To Guide will be initially launched through the FREE subscription service. The Guides will then be available for access online here below. There will also be a Printer Friendly version and a PDF version for easy download if required.
