Design Rules for circuits to be conformal coated by Selective Robot

Selectively coating a circuit board with a robot can be a simple process.

However, for too many designers, conformal coating is simply a part number, to be applied to circuit boards.

This failure to appreciate the subtleties of the selective robot application process can result in an un-coatable (at least as specified) assembly process.

Follow our conformal coating design rules and save time, money and pain!

Every company has its own horror stories and folk lore about the challenges faced when conformal coating an assembly to successfully meet the designer’s specification.

It is almost certain that the majority of these ‘nightmare’ scenarios could have been headed off during the design and or prototyping stages of development.

Trying to coat connectors right up to the base of the component is going to challenge even the best engineers. Apply some conformal coating Design Rules and avoid these problems!

The design rules for conformal coating are straightforward.

Follow them and you can save money and time in your application process.

However, if the rules are not followed, the resultant circuit board design can challenge even the most sophisticated conformal coating system and its operator to achieve the finish desired.

Design Rules for Conformal Coating that could save you money, time and heartache

Unfortunately, for too many designers, conformal coating is simply a part number to apply to printed circuit boards.

Unfortunately, for too many designers, conformal coating is simply a part number to apply to printed circuit boards.

For manufacturers embracing lean philosophies and applying conformal coatings, a failure to appreciate the subtleties of the application process can result in an un-coatable (at least as specified) assembly process.

Nexus have split the conformal coating Design Rules into 4 sections.

These are:

  • General Design
  • Selective Robot
  • Dipping
  • Batch Spraying

The design rules for conformal coating are generally straightforward.

Follow them and you can save money and time in your application process.

However, if the rules are not followed, the resultant circuit board design can challenge even the most sophisticated conformal coating system and its operator to achieve the finish desired.
