Many of the lead-free solders can emit alpha particles. Typical lead-free alloys containing tin, silver, bismuth,
antimony or copper could be contaminated with small amounts of lead and therefore alpha emitting
Polonium210. The contamination of lead-free solders is particularly suspect for alpha particle emissions when
derived from recycled metals. Pure Technologies certifies and guarantees the alpha emission quality of all its
lead-free solders to ensure consistency with the customers' low alpha requirements.
