Solder The core associated with silicon cable widely used in RC cars, those silver-plated to boost the energy efficiency happens to be used most of the time. The silver component may move to solder and make use of a tin solder normal phenomenon occurred erosion alleged silver, power effectiveness is probable is weakened. It seems feasible to work for this behavior by in which they use the silver solder containing silver to solder in, and kept to a minor decrease in efficiency.
