Just make sure that any solder that you do use doesn't say Pb on it which means lead.
The solder you're using is a combination of 95% tin and 5% antimony solders also bearing silver exist however the SB SN mix is the most common.

It often requires more courage to dare to do right than to fear to do wrong.
"To move ahead you need to believe in yourself...have conviction in your beliefs and the confidence to execute those beliefs.
It is actually the other way around. Silver bearing solder is the most common. 95/5 is also available, but is not used as much as the regular stuff because it is less tolerant as far as heat is concerned.
