The object
Iver Anderson invented a lead-free SAC solder alloy for electronics assembly. The tin-silver-copper alloy provided electronics makers with a workable lead-free solder for circuit-board assembly, supporting the industry-wide move away from lead-containing joints. It became especially consequential as environmental rules tightened worldwide.
