Lead-free solder is a type of solder that does not contain lead, a toxic metal that was commonly used in soldering in the past. Due to environmental and health concerns, many countries have banned the use of lead in soldering, leading to the development and adoption of lead-free solder. Lead-free solder typically contains a combination of tin, silver, and copper, and is used in electronic and plumbing applications as a safer alternative to traditional lead-based solder. **
