Effects of Conformal Coatings on the Corrosion Rate of PCB-based Multielectrode-Array-Sensor

Multielectrode array sensor (MAS) for monitoring corrosion of Cu is developed using typical printed circuit board (PCB) processes. Its robustness is tested in highly corrosive HCl solutions with two different conformal coatings, namely acrylic and epoxy. It is found that the corrosion inhibiting na...
