Cable assembly and strand tinning: Wide range of fluxes
As a developer and producer of fluxes for electronics production, we also offer a wide range of fluxes for cable assembly, especially for the strand tinning process. The aim when using a flux is to achieve uniformly good tinning using leaded or lead-free solders. It must be possible to control the tinning process so that only a defined length of the strand is tinned.
Any flux residue must not have any effect on the subsequent use of the end product, for example due to corrosion or low surface electrical resistance (SIR). Furthermore, it is important that the flux used does not penetrate the cable and strand sheathing, as otherwise the strands and wires could corrode. Furthermore, the cable sheathing may be damaged in this case.
The fluxes must meet the temperature requirements of the respective process. If the solder bath is run at higher temperatures, the fluxes must remain active. This is particularly important if the strand coatings are "burned off" during the soldering process.

Critical requirements for fluxes in cable assemblies
No Clean-flux solutions ensure minimal residues that do not compromise electrical surface resistance (SIR) or cause corrosion. The applied flux must not penetrate the cable coating or strand coating, as this could lead to corrosion or material damage. On top, the flux must withstand the high temperatures of wire tinning and soldering processes without degrading in performance. If the solder bath operates at elevated temperatures, the flux must remain active, particularly when strand coatings are intentionally burned off during soldering.
Optimized flux performance for cable assembly and wire tinning
Emil Otto's high-performance flux solutions are tailored to meet the exact demands of cable assembly, ensuring reliable wire tinning with defined length control and protection against corrosion, preserving the integrity of strands and coating. No Clean-flux options to minimize post-process cleaning and temperature-resistant fluxes ensure stable performance in high-heat soldering processes.
