By incorporating the advanced technology of Parylene coatings, smart meter life expectancy is improved in ways other methods cannot."

Article Summary

  • Despite the technical maturity and value of smart meters, there is potential for component failures.
  • Smart meter failure can be expensive and result in warranty claims, failure analysis costs, unnecessary logistics, and brand damage.
  • Conformal coatings are a logical and necessary method of protecting smart meters from harsh environments.
  • Parylene provides superior conformality, with a uniform, controllable thickness that is pinhole-free.
  • It is inert, thermally stable between -200°C and 125°C and higher, has a dielectric strength of 7 kV/mil, and provides excellent barrier protection against moisture, corrosives, chemicals, gases, and fungus.
