Lead-free solder nitrogen inerting

The amount of dross depends on oxidation characteristics and the concentration of constituent metals in the alloy. For example, tin, which is a major constituent of most lead-free solder alloys, undergoes rapid oxidation in air. Therefore, high-tin-content, lead-free alloys will produce high dross levels if measures such as nitrogen inerting are not taken to impede its formation. [Pg.572]

Based on theoretical considerations, the formation of dross is five to seven times greater for lead-free alloys compared to 60Pb-40Sn or eutectic Sn-Pb alloys because of the increased tin content and soldering temperature [7]. In certain minimum cases, the dross doubles or triples. In addition to better yield and increased reliability, substantial reductions in dross formation to reduce cost are another reason for implementing nitrogen inerting. [Pg.581]
