Explaining the mechanism of electrolysis and prevention methods to minimize the risk of defects!
One of the failure modes of metal film chip resistors is a phenomenon called "electrolysis." When electrolysis occurs, the resistance value may change, and in some cases, it may completely break. What should be considered to prevent electrolysis and safely use chip resistors? 【Contents】 ■ What is electrolysis? ■ Electrolysis in a narrow sense ■ Galvanic corrosion ■ Causes of moisture intrusion ■ Methods to prevent electrolysis ■ Experiment on substrate coating agents *This document is a technical resource that provides a detailed explanation of the mechanisms and prevention methods of electrolysis.
