Fluxes as sustainable concentrates for electronics manufacturing
The flux concentrates from Emil Otto are of particular interest to customers who require large quantities of flux or manufacture abroad. All granulates can be transported without hazardous substance identification and with a significantly reduction in size.
A flux becomes a hazardous substance if it contains alcohol, among other things. The flux concentrates are free of this as the customer mixes the alcohol or the alcohol-water mixture on site. The mixing of the flux is very simple because each concentrate contains the necessary information which liquid has to be added to the concentrate and in which dosage. Furthermore, the granulates can be packaged more easily and with less volume, which also reduces transportation costs. Due to this transport optimizations the flux concentrates can be transported economically over long distances, as freight carriers charge very low costs for non-hazardous goods. The concentrates include fluxes for wave and selective soldering as well as manual and dip soldering.

What are flux concentrates?
Flux concentrates from Emil Otto are specially formulated chemical mixtures that are supplied in concentrated form. They must be diluted before use to ensure the optimum solids content and the correct activation in the soldering process. This flexibility offers numerous advantages over prefabricated fluxes:
Concentrates are not classified as hazardous goods, which means that they can be transported at a lower cost and stored without environmental restrictions.
Concentrates can be shipped in reduced volumes, resulting in lower transportation costs.
When diluted, concentrates ensure a stable and reliable soldering quality.
In terms of process reliability and stability, the concentrates in their diluted form are in no way less effective than their original liquid product forms.
Concentrates are more durable, since the aspect of shelf only becomes relevant after mixing.
