Leaded solder was the industry standard for decades until environmental regulations limited its use.
A solda com chumbo foi o padrão da indústria por décadas até que regulamentações ambientais limitassem seu uso.
Leaded solder was widely used in electronics manufacturing and repair throughout the 20th century in both Brazil and the USA. However, due to environmental and health concerns related to lead exposure, its use has been heavily restricted or banned in many applications since the 2000s, particularly in consumer electronics under RoHS (Restriction of Hazardous Substances) regulations. In Brazil, restrictions align with international standards, making lead-free solder increasingly common in industries. Understanding the distinction between leaded and lead-free solder is important for professionals in electronics, plumbing, and manufacturing sectors.
