Corrosion of the Materials in the Electrical Connectors

Electrical connector is an important component in electronic system, and its reliability directly affects the reliability of the whole system. Corrosion often occurs in the use of electrical connectors and leads to failure. This paper summarizes the corrosion failure analysis process of three kinds of connectors. The failure types include fluorine corrosion, electrolytic corrosion and sweat corrosion. The quality assurance measures of Anticorrosion for electrical connectors are expounded.
