Pb solder was the industry standard for electronics manufacturing and plumbing applications throughout the 20th century in both Brazil and the United States. However, due to health and environmental concerns related to lead exposure, many countries have implemented regulations (such as RoHS in Europe and California's Proposition 65 in the USA) restricting its use. In Brazil, regulations have gradually phased out Pb solder in new applications, though it may still be found in maintenance and repair work on older equipment. Understanding the distinction between Pb solder and lead-free alternatives is important for professionals in electronics, manufacturing, and plumbing sectors.
