Yokomo YOKYTSS1 Silver Solder - RC Electrical Upgrade  [YOKYTSS1]

Silver-alloy solder for model electronics

This solder is offered as a specialist option for RC electrical joints where silver-plated or silvered conductors appear. Many silicone-insulated RC cables use a silver finish on the conductor to boost conductivity, and ordinary tin-based soldering can sometimes erode that finish or cause silver migration, which may raise contact resistance over time.

The YOKYTSS1 racing silver solder includes silver in its composition to better match silver-plated conductors and to reduce galvanic action at the joint between differing metals. In service this can help preserve low contact resistance at battery leads, motor leads and other high-current connections on scale models.

When used on the bench or in the field, this material is selected to preserve electrical continuity rather than to add mechanical strength. Typical practice for small RC wiring applies: prepare the surfaces, apply solder so it flows to both surfaces, and avoid overheating that could damage insulation or nearby parts. Expect slightly different wetting and flow behavior compared with plain tin solders when working with silver-plated wires.
