Process residues and other secondary materials can be used to produce new and pure solder alloys. Tin and lead smelters buy up residues and recyclable material for this purpose throughout Europe. These materials are prepared with the help of various pyro- and hydrometallurgical processes. During the metallurgical production steps, the alloys are combined into the correct composition according to standards or customer specifications. After each refining step, an analysis is carried out in the laboratory, where the samples are analysed using state-of-the-art technologies and extensive metallurgical know-how. Practically all types of tin and lead residues can be processed in a resource-saving, environmentally friendly and economical manner. In the production of micro-alloyed solders for electronics production, doping of e.g. Ge, Ni, etc. with pure metals is carried out. These are purchased from manufacturers and alloyed according to the customer’s requirements. The benefit for the customer is that the complete process is in one hand and the elements can be adjusted down to the ppm range.
