[Special Use Case] Measures Against Copper Erosion and Fine Wire Erosion

We will introduce measures against copper and fine wire corrosion.

Copper erosion and fine wire erosion This phenomenon occurs when soldering coil wires for relay components, earphones, microphones, etc., causing the wire to become thinner. Depending on the severity, it can lead to defects such as wire breakage. Causes of copper erosion Copper erosion occurs when the copper in the coil wire forms compounds with Sn in the solder and diffuses into the solder. Pb-free solder contains a higher amount of Sn, making it more susceptible to erosion. Countermeasures for copper erosion By adding a large amount of Cu to the solder alloy, it is possible to reduce the diffusion rate of Cu from the coil wire, thereby decreasing copper erosion. We offer solder with resin for copper erosion countermeasures and bar solder, so please contact us for more information.
