Logannsan, you may want to check into this a little more with your customer to find out what 2 is. It could be as Vlad say's 2Ag -silver, or it could be 2CU -copper or 2Ni- nickel. Also check this form for 62Sn 36Pb 2Ag just my 2 cent. Regards

Strange we use the 179~C eutectic 62/36/2 solder paste as standard in Europe. It is indeed 2% Ag in fact we dont sell 63/37 paste or very rarely. I think if you mix a little 60/40 powder with the 2% Ag alloy this overcomes the tombstoning problem.
