Silver Solder, 62/36/2%, 21AWG, .032", 1lb
These solders are specially formulated to be used with gold and silver plated contacts to prevent the leaching of precious metals which is easily dissolved into tin. Leaching is the tendency for tin/ lead-bearing solder to dissolve metallizations during reflow operations. The rate at which silver leaches into molten tin/ lead solder alloy is retarded by using solder alloys which contain a small amount of silver. These solders contain 2% silver in the alloy.
