Nexus July Newsletter almost ready to be sent out

Next week Nexus are launching two really interesting articles as part of the Nexus newsletter.

The first is a guest article from Warren Boomer of Thin Film Partners on why Parylene coating can cost more than traditional liquid conformal coatings can and how the price is calculated.

The second is  a review of where to start when selecting a conformal coating application process by Dr Lee Hitchens of Nexus.

Both can be read in the July newsletter being launched next week.

Make sure you are signed up now to receive this monthly technical email.

This month’s newsletter contains two great articles on designing and selecting conformal coatings, a launch of a new section on practical masking and all of the many updates this month to the eBook.

Here’s an insight into what its all about!


Why selecting a conformal coating can cost you a fortune!

Choosing a coating to protect your product should be easy.

So, why does it go wrong so often?

Find out why and how to stop it happening.


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?”

If so read on and prevent it happening to you.

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.

What are the critical points to correctly design your conformal coated circuit board to meet the highest standards?

When designing for reliability with conformal coating then there are several important areas to consider for the product:

  • Reliability Requirements
  • Life Cycle
  • Environment
  • Materials and Parts selection
  • Electrical Effects

The purpose of the conformal coating is to protect the printed circuit board. This is to increase the circuit and product reliability.

The purpose of the coating is to protect the circuit. Understanding the key points will ensure that the coating does its job

To ensure the right level of reliability is achieved with the conformal coating then a complete understanding of the design requirements for the circuit board is critical.

This should be the starting point for most engineers when considering designing for reliability.

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.

Unfortunately, too many designers see conformal coating as a part number and do not understand the application 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.

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
