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

How do I select a conformal coating?

I am regularly asked how I would go about choosing a conformal coating?

I normally respond to the person involved by asking an awful lot of questions and they wonder what they got themselves in to!

Why do I have to ask a lot of questions?

The questions are there because choosing a conformal coating process is a complicated process usually balancing a lot of important trade-offs and compromises.

When I consider the question I actually see three major parts of the complete process.

These parts are:

  1. The conformal coating material
  2. The application method
  3. The circuit board design

When you consider these three points you have to balance them to create the best compromise process solution that suits your requirements.

This is what I call the Holistic Approach to conformal coating.

So, what should you do next?

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
  • Supplier performance and availability
  • Price

To find out more about these factors visit Nexus and see how we recommend you select a conformal coating through the holistic approach.

 

How to Select a Conformal Coating Process – The Holistic Approach

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:

  1. The Conformal Coating Material Requirements
  2. The Application Method Selected
  3. 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 Announce Conformal Coating Research Program

Nexus Conformal Coating Research Program Some of the most Frequently Asked Questions that are asked of Nexus include:

  • What is the the best conformal coating for my Printed Circuit Boards (PCBs)?
  • How good is the Conformal Coating I am using right now?
  • Can I switch the conformal coating I am currently using?
  • Just how good are the new environmentally friendly conformal coatings ?
  • What conformal coating process should I use to give me the best protection for my board?
  • Can I use a lower cost conformal coating and still achieve the same level of protection?
In an effort to answer these questions and many more Nexus will begin Phase 1 of a full ongoing Research Program in August.This Research will identify the best conformal coating materials, conformal coating application processes and ultimately value for money for customers in the world of electronics printed circuit board protection.
The First Phase of the Research will:

  • Compare and rank the protective capability of a number new and well established conformal coatings including both liquid and parylene based materials, against single aggressive environments as well as the sequential load to provide a reliability enhancement index.
  • Compare and rank the performance capability of the commercial application methods including selective spraying, batch spraying, dipping and brushing.
  • Provide a cost comparison of coated assemblies and determine cost-benefit comparisons between coating materials and application processes combinations.

This research will be open to join by users and suppliers alike who wish to access the full unabridged data.

Find the Distributor for Conformal Coating Suppliers in your region with Nexus

Nexus have introduced a section to allow distributors to be linked to the conformal coating material and equipment suppliers. This allows the user to find the local representative for a material quickly and easily all within the same resource.

This is also linked through the Material Selection Guide so once you have decided which conformal coating materials you want further information from you can contact the distributor if they have signed up for the service.

This Service goes live on Monday 18th June.

For further information go to Nexus and look at THE INDEPENDENT  conformal Coating Resource.

 

Using the Conformal Coating Materials Selection Guide From Nexus

The Conformal Coating Selection Guide is now ready for users to compare their conformal coating material requirements.

Users will be able to specify their technical requirements for a conformal coating material and the location where the coating is to be used and the Nexus Selection Guide will provide different materials FROM DIFFERENT CONFORMAL COATING COMPANIES from around the world. This allows customers to compare technical specifications and supplier information from one portal providing INDEPENDENT power to the customer.

To use the system follow these simple instructions:

  • Log on  / sign up for Nexus
  • Indicate the Country or Region you would like to buy the coating in (some materials are not available globally)
  • Type in your technical specifications
  • Choose from the selection of conformal coatings FROM DIFFERENT MATERIAL MANUFACTURERS
  • Request further information from the Manufacturers or distributors

ITS SO EASY!

Even better you can request FREE help on selection and also use Nexus’s buying Service to negotiate to buy the coatings at a discounted price.

Leading conformal coating material manufacturers like Humiseal have joined the Nexus Conformal Coating Material Selection Guide Service.

Select your conformal coating material from multiple suppliers and find your contact for that material in your region of the world.
