New electronics coating lowers cost of moisture protection for PCBs
3M has launched the new 3M™ Novec™ Electronics Coating EGC-1700, to provide a fast and low cost way of protecting sensitive electronic circuits and assemblies against moisture and corrosive chemical environments. Novec EGC- 1700 dries quickly to form an extremely thin, yet remarkably repellent, light-duty coating. This new product now makes it viable to apply moisture protection to inexpensive circuits and assemblies, where the cost of most conformal coatings is prohibitive.
It is a clear, low viscosity solution of a fluorochemical acrylate polymer coating, diluted in a 3M Novec hydrofluoroether solvent. The solvent is nonflammable and has low toxicity, zero ozone- depletion and low global warming potential, to provide acceptable workplace safety and environmental properties. When applied to clean and moisture-free surfaces such as copper, aluminium,ceramics, steel, tin or glass, Novec EGC-1700 dries quickly to create a thin,transparent, protective film with excellent anti-wetting, antistiction, anti-migration and anti-corrosion properties (Plate 5).
