"GB/T 20633.1-2006 Coatings for carrying printed circuit boards - Part 1: Definitions, classification and general requirements" specifies the definition, classification and general requirements for electrical insulating materials applicable to Coatings for carrying printed circuit boards. The standard equivalents IEC 61086-1:2004, which clarifies the terms and definitions of Coatings, such as "Coatings" refers to electrical insulating materials used on the surface of printed circuit boards to resist atmospheric corrosion. The standard also classifies Coatings, including general-purpose, high-Reliability and aerospace types, and specifies material class codes and Resin model codes. This standard does not deal with the compatibility requirements of coatings and printed circuit boards, and is applicable to the design, production and quality control of coatings for carrying printed circuit boards.
