Solder Wire STANNOL | Kristall 400
Solder Wire STANNOL Kristall 400 electronics soldering wire is based on a “No-Clean” flux. It has been developed for high requirements for conventional soldering and for soldering SMDs in industrial production and for repair and resoldering.
The wire flux in Solder Wire STANNOL Kristall 400 is a halogen-free activated flux based on synthetic resins with organic acids. it combines high activity and good flow characteristics in an outstanding way with small amounts of solid and electrically safe residues.

Solder Wire STANNOL Kristall 400 can be used for manual and machine soldering in the area of electrical engineering and electronics.
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 Stannol Kristall cored wire. Severely
contaminated soldering iron tips should first be cleaned and pre-tinned using Stannol Tippy, then wiped on a clean, damp
sponge before re-tinning with Kristall cored wire.
Stannol Kristall flux 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
Stannol Kristall solder wires, recommended working practices for hand soldering should be observed as follows:
a) 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.
b) Apply Kristall 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.
c) Remove solder wire from the workpiece and then remove the iron tip.
d) The total process will be very rapid, depending upon thermal mass, tip temperature and configuration and the
solderability of the surfaces to be joined.
Cleaning: Stannol Kristall flux cored solder wires have been formulated to leave pale flux residues and to resist spitting and
fuming. In most industrial and consumer electronics applications cleaning will not be required and the product may
therefore be used to complement a No Clean wave soldering or reflow process or to allow repairs to cleaned boards without
the need for a second cleaning process.
Should residue quantity be an important consideration, Stannol X39B flux cored wire may be specified if a halide free
product is required. Stannol Kristall 502, 505 and 511 offer good activity and consequently cored wire flux contents and
hence residue levels may be reduced in comparison with equivalent conventional products.
Should cleaning be required, this is best achieved using Stannol Flux-Ex 200B or Stannol Flux-Ex 500 solvent cleaner. Other
proprietary solvent or semi-aqueous processes may be suitable but saponification is not recommended.
