Solder The core connected with silicon cable widely used in RC cars, those silver-plated to enhance the power efficiency is used usually. The silver component may relocate to solder while making utilization of a tin solder normal trend occurred erosion alleged silver, power effectiveness is probable is weakened. It seems feasible to get results for this behavior by in which they normally use the silver solder containing silver to solder in, and kept to a minor decrease in efficiency.
