Materials we recycle. As a recycler, we are focused on purchasing scrap tin in a variety of forms and alloys. More specifically, solder alloys containing tin are an everyday item for us.
At least half, and in many cases, more than half of the metal (solder) purchased for electronic manufacture is wasted as it becomes tied up in dross. With the advent of lead free solders as well as the spike in tin prices during 2008 the moderate economic pain of dross generation has become acute.
As much as 70% of bar solder can be wasted as solder dross and with SAC 305 now at the 25/Lb level and even leaded solder costing almost twice as much as in previous years it is a major issue. Recovering your own dross could save you money but it is not an undertaking that should be done lightly.
The salt slag generated ranges up to 35 pct of the melt charge in rotary furnaces. Higher quality scrap is melted in reverberatory furnaces, using a flux consisting of equal parts sodium chloride and potassium chloride with 2 to 5 pct cryolite. Dross from this type of furnace ranges up to 10 pct of the melt charge.
Dross is formed when molten solder on the surface of a solder pot or bath comes in contact with oxygen forming tin oxides. A thin film of dross in a solder pot is desirable as it slows down further oxidation of the solder as long as it is not detrimental to the integrity of a solder wave.
