Fretting Corrosion in Ruggedized Backplane Connectors


Fretting corrosion caused by the relative movement of contacts during continual shock and vibration in harsh environments is the leading cause of failure in aerospace, space, and defense systems platforms. Fretting is defined as accelerated surface damage occurring at the interface of the electrical contact due to micro-movements caused by temperature variation, vibration, and shock. This causes an increase in electrical contact resistance and eventually leads to an electrical failure.

This webinar will focus on common contact technologies used in the connector industry and how to avoid fretting corrosion by implementing Hypertac® hyperboloid contact technology in your connector designs. This contact technology offers proven benefits and our engineering teams over the years continue to creatively adapt the concept to meet the needs of so many diverse applications.
