No-clean soft-solder wire for high-demand applications in electronic and electrical engineering.
FELDER ISO-Core® solder wires are manufactured of the same highly pure alloy components according to international standards like FELDER ISO-Tin® electronic solders.
The fluxes have a high temperature resistance!
The fluxes do not result in corrosion in non-iron metals and have the highest surface resistance values. Therefore, they can remain on the soldering joint.
In connection with lead-free alloys Sn95,5Ag3,8Cu0,7 the qualities of „EL“ and „ELR“ were positively rated by Siemens Berlin, certification center CT MM 6, already in January 2001.
