Conformal coating selective robot spray valve comparison

Nexus examine the different types of conformal coating valves that can be utilised with the different selective robot platforms.

The valves can be used in isolation or in combination to provide different conformal coating performances dependent on the coating pattern required and the material type used.


Parylene vapor deposition application method

Nexus examines the Parylene conformal coating vapor deposition application method.

We examine the key points of the production process including complexity, equipment, process type, factors affecting performance and the advantages and disadvantages of the technique.


Conformal coating dipping summary

Nexus examines the dip conformal coating application method.

We examine the key points of the production process including complexity, equipment, process type, factors affecting performance and the advantages and disadvantages of the technique.

Why write Nexus?

Dr Lee Hitchens has been working in the electronics industry and the area of conformal coatings for over 25 years in various areas including sales and technical support.
He has also uniquely been training people for almost the same amount of time in all areas of conformal coating whether that is materials & equipment selection, process development or troubleshooting to help them solve their particular problem.
In 2015 he decided that the industry needed a specific place where all of the useful knowledge on conformal coatings could be collated for users to find easily and use in their own production process.
So, Nexus was born and he began writing the website.


Welcome to Nexus

Nexus is an independent website and eBook dedicated to providing technical and commercial information on all areas of conformal coating, Parylene and thin film technologies and the related topics connected to the process.

The knowledge we provide is from many different people from the world of conformal coating that you should find useful.

We examine all areas of conformal coating including materials, selection, application, troubleshooting, process control, design, basic knowledge and rework.

We provide technical information on thin film coatings that include conformal coatings, fluoropolymers, metal oxides and other ultra thin coatings, plus encapsulates and potting compounds, and a specialist cleaning section.

These specialist materials are used to protect high value products such as circuit boards exposed to aggressive elements in the environment.


Practical conformal coating masking summary

Techniques for masking components, connectors, test points, mounting holes and via’s have been developed with years of experience and standard methods now exist.

Nexus have collated a range of masking videos covering different materials including masking tapes, dots, liquid latex and masking boots.
