Gold scavenging is a well-proven consequence of using tin-based solders on gold metallizations. Scavenging rapidly dissolves large quantities of gold during the solder reflow process and can lead to complete and irreparable destruction of gold conduction patterns. Tin-based alloy scavenging can completely destroy a thick-film gold layer in less than 30 seconds.

Indium-lead solders cause appreciably less scavenging and are satisfactory for use on gold films thicker than 1 micron. Gold is essentially insoluble in indium.

This kit contains 3 different solid (no flux core), 0.76mm (0.030″) diameter, indium-based solder wires. These Pb-containing and Pb-free alloys reflow at temperatures ranging from 143°C to 310°C.
