Flux F3-further development of flux F1.Hemore activeand allows solderingmore

oxidized and difficult places.

Steel, nickel-plated Chinese connectors, old panels, zinc, silver - you can now solder all this without any problems.

The former safety for radioelements inherent in flux F1 has been preserved. However, F3 flux has a lower resistance after drying: about3 Mohm. It is necessary to wash it off only if this circumstance can affect the operation of the circuit.
