Originally developed for telecommunication applications in order to reduce gold consumption and cost while still maintaining functionality and performance.
TPG has designed and developed its own selective gold plating machines for the last 40 years. The recently developed, Cyclon machine, is the world's only fully automatic coax connector selective gold plating line - capable of plating selectively either externally or internally a large volume of loose parts. Some applications have even been designed to graduate the internal thickness of plating in the bore so that there is a thicker deposit in the contact area further in the connector than at the opening.
TPG can design and implement a selective gold plating solution for most applications - resulting in huge gold savings for our customers.
