Right-Angle Solder Lugs typically have a right-angle shape with one or more solder feet for solder connection to a circuit board. The right-angle shape allows lugs to be easily soldered to electronic devices or circuit boards, providing a reliable electrical connection. Lugs are usually made of highly conductive metallic materials such as copper or carbon steel. They can also be nickel-plated, silver-plated, etc. to improve electrical conductivity and corrosion resistance.
