Abstract

The article analyzes the scientific and technical literature data concerning the main methods of removing moisture-proof electrical insulation coatings from printed circuit boards and assemblies during their repair and modification. Characteristics, advantages and disadvantages of the removal of electrical insulation coatings by dissolution, peeling, mechanical, thermal and micro-jet methods are presented. The above methods mentioned for polyurethane, epoxy, acrylic, organosilicon and parylene electrical insulation coatings are considered and the most optimal methods depending on the nature of the material are determined.
