Corrosion Lifetime Estimation of Printed Circuit Board in Marine Atmosphere Environment Using Multiphysics Simulation

Printed Circuit Board (PCB) is a major component of the electronic device and it has been used in diverse extreme environment such as data center near coast. In this study, simulation model was to predict corrosion lifetime PCBs marine atmospheric environments. The devised considering dimensions PCB, biased voltage, salt To prove validity proposed model, spray acceleration test conducted. Finally, life equations according geometrical environmental factors were proposed.
