Abstract :
Parylene coating tests of circuits produced with various no-clean soldering fluxes are conducted to determine the impact of no-clean circuit processing on the Parylene coatability of these boards. The properties and characteristics of Parylene conformal coating are described. Surface insulation resistance test procedures and results for no-clean flux/no-clean soldered and Parylene coated circuit samples are summarized
