Making a tin-lead alloy for pastes, as for raw bars, is the same. It is a smelting and refining process governed by the market prices for those metals.

All of the value added and "wizardry" come in the making of the solder powder, designing and making the flux vehicle systems.

Get in contact with the development people at Indium, OMG Americas, Alpha Metals, Qualitek, AIM, Kester, etc, etc. All of these companies make their own metal powders and develope solder pastes for the electronics industry.
