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.


Did you read the June Edition of the Nexus Newsletter?

We had two great articles on the Critical areas of designing for conformal coating and Why selecting a conformal coating can cost you a fortune!

We also launched our new Practical conformal coating masking section.

Nexus June Newsletter available to download

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.


NEW Practical masking for Conformal Coating Section

Nexus have collated a range of conformal coating masking videos looking at different materials including masking tapes, dots, liquid latex and masking boots. Find out more

Why hybrid processing of traditional conformal coatings and fluoropolymer, nanocoatings could improve your reliability

Traditional conformal coatings protect the circuit well if they are selected correctly. However, where the coating is not applied there is little or no protection.

Nano coatings (FC), ultra thin coatings of thickness <2μm, provide hydrophobic properties and don’t need masking.

The lack of need for masking is due to the coating thickness being so thin that there is no resistance to removing the material. This means the FC can coat all of the circuit including connectors and offer the protection of the coating.

However, this very fact means the FC coating is delicate to handle and may not provide the long term reliability needed like a traditional coating.

So, what if we could combine the two materials and have the properties of both?

The circuit board would have:

  • The long term protection due the traditional conformal coating
  • The hydrophobic nature due to the FC coating
  • Protection all across the circuit board

Nexus have been experimenting wth dual coating with both traditional conformal coatings and ultra-thin coatings.

A circuit board with both conformal coating and a fluoropolymer (FC) coating applied. The FC material in the connector repels the water droplet that would normally capillary into the component.

The results are extremely interesting for potentially increasing the protection of the circuit without adding a significant amount of cost to the process.

Nexus Newsletter looks at Conformal Coating Subcontract Services and houses

In this issue Nexus reviews subcontract conformal coating services provided by coating houses and the problems faced today. If you want to subcontract out then read this article. Nexus is also looking closer at conformal coating defects related to the IPC Standards and why they occur? The technical article Who Do Defects Occur? gives some insight into how to solve most of the main issues that can stop the line and cause a lot of heartache.

Also, we are introducing a new section at Nexus this month called Conformal Coating101. This section answers all the questions about why we use coating, what it does etc and answers many of the questions we are regularly asked.

Finally, Nexus starts its Conformal Coating Workshop Program off in October and November in China and India, respectively and we confirm further dates for North America and Europe in the New Year.

Nexus Conformal Coating Newsletter in September

The next Nexus Newsletter will be published in the middle of September. Covered within the issue will be articles including:

Main Feature – Subcontract Conformal Coating Services – A necessary evil or the ideal solution.

Technical Article – So you are considering outsourcing – What does that really cost?

Ask the Experts – Users and suppliers of subcontract service explain their viewpoint on challenges found in contract coating.

Nexus August Newsletter is now available and Features Conformal Coating AOI and Inspection

In the August issue Nexus investigates key conformal coating inspection issues faced today by users and suppliers of conformal coatings, services and equipment. Nexus is also pleased to confirm the participation of Conformal Coating Consultant, Bob Willis, in its online conformal coating webinars series and Global Workshop & Conferences Program which launch soon across Asia, Europe and North America. Also, we are pleased to announce that Nexus will be exhibiting at Nepcon China next month. Finally there is an interview with Nexus Consultant & Parylene Expert Mel Popovich.

FEATURE: Conformal Coating Inspection: What do you see? Inspection is a key area in conformal coating This feature looks at the standards, what they mean and what you see with new automated conformal coating inspection technology today.

FEATURE: Conformal Coating Defects: Definitions and images of common conformal coating failure mechanisms Nexus examines the defects you can find in conformal coating so you can recognise what your problem is!
