Solvent-based conformal coatings have been used in the U.S. for many years to protect printed wiring boards (PWB) in automotive, military, and other applications. With changing laws and environmental concerns, strong emphasis is being placed on conversion to solventless coatings of all types. This paper describes the development, testing, and prove-out of a solvent-less conformal coating that works with no-clean fluxes and pastes and still maintains high reliability in the harsh automotive underhood environment.
Automotive printed wiring board manufacturers succeed with 100 % solids conformal coatings and no-clean flux
