Soldering wires
ISO-Core® for fine soldering in the electronics and electrical engineering as well as in the telecommunications and electric motor construction.
FELDER ISO-Core® soldering wires are made of the same high-purity alloy components according to the international standards as FELDER ISO-Tin® electronic solders.

The flux is characterized by its high temperature resistance. The bright solid flux residues of this soldering wires do not cause corrosion in non-ferrous metals. They can therefore remain on the solder joint. An optimum wetting and spreading values exceeding the normal standards turn it into a top product in flux-cored solder wires, also in its lead-free quality.
In combination with the lead-free alloy Sn95.5Ag3.8Cu0.7, the qualities of "EL" and "ELR" were assessed positively by Siemens Berlin (certification authority CT MM 6).
