Bismuth-based solder has become increasingly important in both Brazil and the USA due to environmental regulations like RoHS (Restriction of Hazardous Substances). In manufacturing hubs, particularly in São Paulo and in US electronics centers, the shift from lead-based to bismuth-based solders reflects global compliance with environmental standards. The technology is particularly valued in industries dealing with sensitive electronic components where lower processing temperatures reduce thermal stress on circuits.
