362 & 366, July 2007
Multicore flux cored solder wires provide fast soldering
on copper and brass surfaces as well as solder coated
materials. Activity of the halide activated versions on
nickel is also good depending on the state of oxidation of
the nickel finish. The good thermal stability of Multicore
fluxes means they are also well suited to soldering
applications requiring high melting temperature alloys.
Cleaning: Multicore 362 and 366 cored solder wires have
been formulated to leave pale flux residues and to resist
spilling and fuming.
Cleaning will not be required in most situations but if
necessary this is best achieved using Multicore MCF800
Cleaner (see separate technical data sheet). Other
proprietary solvent or semi-aqueous processes may be
suitable. Saponification may be viable but customers must
ensure that the desired level of cleanliness can be achieved
by their chosen system.
