Conductive anodic filament expert joins Isola
Isola Group S.à r.l., has recruited Dr. Antonio “Tony” Caputo to its Analytical Services Lab in Chandler, AZ.
Dr. Caputo’s work at Isola will focus on research on the chemical nature of Conductive Anodic Filament (CAF) failures; this is a failure mode in printed wiring boards (PWBs) that occurs under conditions of high humidity and high voltage gradients. The ability to identify how CAF forms chemically, and to understand the fundamental reaction conditions that accelerate CAF formation, will enable Isola to introduce new laminate systems that are more CAF resistant. Dr. Caputo has spent over a decade studying electrochemical corrosion failure modes and researching the importance of CAF. He has worked in collaboration with the Center for Microelectronics, Assembly, and Packaging (CMAP) and BlackBerry.
