Bismuth in solder
WebAs a result, alloy solder should be added to tin powder that contributes to the majority of solder paste, such as silver (Ag), indium (In), zinc (Zn), antimony (Sb), copper (Cu), bismuth (Bi) etc. With the trace metals added to tin powder, the melting point of solder paste can be reduced so that PCB assembly can be implemented in quantity with ... WebNov 25, 2024 · The stuff seems to be virtually unknown in the west. You look on reputable distributors, they've got leaded, and they've got tin or tin silver, and they've got the tin bismuth eutectic (58% bismuth, 42% tin), but at138C the melting point is way too low and it's said to be brittle as well. Hell, it's easier to find solder containing gold from ...
