Nano-coatings are being used all the time to protect electronic circuit board assemblies. This is because the base materials they are formulated from are fluorinated polymers that have very different properties to traditional conformal coatings. So, how are the Nano-coatings

What are the main methods for cleaning contamination from a printed circuit board before conformal coating?
Successful cleaning of electronic circuit board assemblies can be achieved by a variety of techniques. These include: • Aqueous wash • Semi-aqueous wash • Solvent & chemical wash • Plasma cleaning Each of these methods can effectively remove contamination. However,
How was the new Molecular Vapor Deposition (MVD) technology developed for protecting electronic circuit boards?
The Molecular Vapor Deposition (MVD®) process was found in 2003 by the SPTS MVD group located in San Jose, California. SPTS provided Nano-film technology processing, equipment and coating services, supplying to multiple markets including: MEMS (Microelectromechanical systems) Semiconductors Industrial Inkjet
What sectors are acrylic conformal coatings used in protecting electronic circuit boards?
Acrylic conformal coatings are used in protecting circuit boards in every sector of the modern world. Historically, they are the oldest material to be used as a conformal coating and the acrylic resin continues to dominate for the time being.
Ten reasons to use Molecular Vapor Deposition (MVD) in protecting electronic circuit boards
Molecular Vapor Deposition (MVD) is a new coating from Thin Film Partners that uses a hybrid coating process of alternating layers of ALD (Atomic Layer Deposition) and CVD (Chemical Vapor Deposition) films combined with a hydrophobic final top coat. The
Do you need UL qualification for your conformal coating?
In conformal coating, there are many International, National and internal company standards for manufacture of coating materials, processing and inspection. The UL standards (and qualification) are used to qualify a conformal coating material to a certain specification. Therefore, it is
Why may I have to clean my circuit board before conformal coating?
Whether to clean circuit boards before conformal coating is a well discussed problem. However, I thought it may be interesting to summarize the reasons for considering the cleaning process before coating as it can be critical to the success of
How thick should I apply my conformal coating?
A regular question asked in conformal coating is how thick should the coating film be? Well, the simple answer is thick enough so the conformal coating works and protects the circuit board. But not too thick as this can cause
Choosing the right conformal coating application process
Choosing the right process for your conformal coating production line is a complicated and involved process. It normally is a case of balancing a number of factors and making compromises. This is because of the three major parts of the
How do I brush coat my conformal coating?
The application of conformal coating using a brush to apply the material to the circuit board is a common practice. This can be done as a complete production process or as a finishing task before final inspection. The technique involves
