    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.

    Default 95/5

    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.
