Overview of Conformal Coating and its Removal Techniques

Conformal coatings are applied to printed circuit board and electronic devices for protection against a variety of environmental, mechanical, electrical and chemical problems,which can effectively improve and extend the service life and reliability of the products. In the repair process and failure analysis of electronic assembly, itis very important to remove the conformal coating cleanly and make no damage to the board.The types of conformal coatings are introduced. And the different removal techniques for the different conformal coating type are explored.
