Nexus has been examining Molecular Vapor Deposition (MVD), a new novel coating technique that may be able to offer superior protection to electronic circuit boards compared to the standard coating technologies like conformal coatings and Parylene.
The MVD process is a hybrid ALD (Atomic Layer Deposition) / CVD (Chemical Vapor Deposition) technique that uses multiple layers of ultra-thin coatings with differing properties to build a completely protective coating.
The results are proving to be highly effective and could change the industry in time.
But where did the MVD technology come from originally?
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)
- Industrial Inkjet Heads
- Display Technology
- Advanced Packaging
- Data Storage Industry
- Genome Sequencing
How is the MVD coating process used in the different industries?
The MVD process provides low temperature vapor deposition of coatings with many different properties in many sectors.
Consider the examples of MVD coating use below:
Surface Energy Control
- Bio-functional layer
Device Protection / Package Sealing
- Moisture barrier
- Corrosion barrier
- Chemical barrier
- Gas/Oxygen barrier
- Anti-reflection coatings
- Electrical insulation
- Conformal films on high A/R
- Adhesion promotion
- Improved thermal stability
- Improved mechanical durability
The MVD process offers great flexibility of processing thin films and it has now been considered for electronics protection.
