What are grounding contact made of？
Grounding contacts are typically made from materials that provide excellent electrical conductivity and grounding performance.
Main component
SMD (Surface Mount Device) grounding contacts are often made from Beryllium Copper, which is known for its excellent electrical conductivity and spring properties. Beryllium Copper is plated and used in SMT (Surface Mount Technology) solder reflow processes, offering superior grounding performance.
Some grounding contacts, like the Soft SMD Grounding Contacts from Laird Performance Materials, have a foam cored contact with a metalized polyimide film outer covering. This material is used for circuit grounding of SMT devices and is designed to be solder reflow compatible, suitable for automatic processing.
This is a newer non-metallic grounding material that has been utilized in the field of power system lightning protection and grounding. FGCGM is a composite material with carbon as its main conductive component, which has strong physical and chemical stability. It is prepared through a combination of chemical processes and physical composite processes, making it different from traditional metal grounding materials .
These materials are chosen for their ability to provide low resistance paths for electrical current, ensuring effective grounding in various applications.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
