Tin-lead solder was the dominant soldering material in electronics manufacturing throughout the 20th century. However, it has been largely phased out in many countries due to environmental and health concerns related to lead toxicity. The European Union's RoHS (Restriction of Hazardous Substances) directive and similar regulations have driven the adoption of lead-free alternatives. In Brazil and Portugal, this transition is ongoing, with legacy equipment and repairs sometimes still using tin-lead solder while new manufacturing typically requires lead-free compliance.
