Study of Overcoming Solder Icicling and Copper Wire Dissolution in an Automated Lead-Free Soldering System
Study of Overcoming Solder Icicling and Copper Wire Dissolution in an Automated Lead-Free Soldering System
Dip soldering remains a common attachment method due to its simplicity, robustness, uniformity and low cost for a number of applications [1]. In particular, the soldering of enameled copper wires to a terminal such as required when making transformers, inductors, electromagnets, motors, solenoids and other devices are often performed by dip soldering.
