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.

These factors can contribute to structural aging in Germany, as the country's infrastructure and policies may need to adapt to support an older population with fewer working-age individuals. **
