RECOMMENDED OPERATING CONDITIONS
Soldering iron: Good results should be obtained using a
range of tip temperatures. However, the optimum tip
temperature and heat capacity required for a hand
soldering process is a function of both soldering iron
design and the nature of the task and care should be
exercised to avoid unnecessarily high tip temperatures for
excessive times. A high tip temperature will increase any
tendency to flux spitting and it may produce some residue
darkening.
The soldering iron tip should be properly tinned and this
may be achieved using Multicore cored wire. Severely
contaminated soldering iron tips should first be cleaned
and pre-tinned using Multicore Tip Tinner/Cleaner TTC1,
then wiped on a clean, damp sponge before re-tinning with
Multicore cored wire.
Soldering process: Multicore cored wires contain a
careful balance of resins and activators to provide clear
residues, maximum activity and high residue reliability,
without cleaning in most situations. To achieve the best
results from Multicore solder wires, recommended
working practices for hand soldering should be observed
as follows:
• Apply the soldering iron tip to the work surface,
ensuring that it simultaneously contacts the base
material and the component termination to heat both
surfaces adequately. This process should only take a
fraction of a second.
• Apply Multicore flux cored solder wire to a part of the
joint surface away from the soldering iron and allow
to flow sufficiently to form a sound joint fillet – this
should be virtually instantaneous. Do not apply
excessive solder or heat to the joint as this may result
in dull, gritty fillets and excessive or darkened flux
residues.
• Remove solder wire from the work piece and then
remove the iron tip.
The total process will be very rapid, depending upon
thermal mass, tip temperature and configuration and the
solderability of the surfaces to be joined.
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 in soldering
applications requiring high melting temperature alloys.
Cleaning: Multicore 400, 502, 505 and 511flux 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.
