Modern electronic systems are based on a printed circuit technology that includes a myriad of processing steps. Many of these steps use chemicals that are precursors to ionic species and residues that remain on circuitry after final cleaning and electrical encapsulation. Although environmental protection is a design requirement, many of the circuits fail during field life and become inoperative. A relationship between field failure and the presence of ionic corrodents has been established by Raffalovich.1
