Yokomo YOKYTSS1 - Racing Silver Solder  [YOKYTSS1]

Silver solder for RC wiring

This solder wire is presented as a purpose-built option for RC-scale electrical joints where silver plating or silvered conductors are used. In many silicone-insulated RC cables the conductor surface is silver-plated to improve conductivity, and routine tin-based soldering can cause surface erosion or migration of silver, which may reduce effective conductivity at the joint over time.

The YOKYTSS1 racing silver solder contains silver in the alloy to better match silver-plated conductors and to limit the galvanic behavior that can occur when dissimilar metals meet at a solder joint. In practice this helps keep contact resistance low at battery leads, motor leads, and other power connections commonly found in model cars.

For field or bench soldering, the material role is maintenance of electrical continuity rather than structural reinforcement. Users typically apply standard soldering technique for small RC wiring: clean the joint, wet solder to the surfaces being joined, and avoid prolonged overheating that can degrade insulation or adjacent components. Because this product is formulated for electrical performance in RC systems, expect modest differences compared with plain tin solder when used on silver-plated conductors.
