PRODUCT DESCRIPTION
Ersin Multicore™ 381 is a rosin-based mildly activated flux
formulated to complement wave and reflow soldering
processes.
RECOMMENDED OPERATING CONDITIONS
Soldering with ERSIN 381 is convenient as it does not call for
any special methods or deviation from the normal hand
soldering practices.
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. Care should be exercised to avoid
unnecessarily high tip temperatures for excessive times. The
tip of the soldering iron should be properly tinned. Severely
contaminated soldering iron tips should be cleaned with
Multicore Tip Tinner/Cleaner.
Soldering Process: Best results will be obtained if the
following recommended operating practice is followed.
a) Apply the soldering iron tip to the work surface. The
iron tip should contact both the base material and the
lead at the same time to heat both surfaces properly. It
should take no more than a fraction of a second to heat
both surfaces adequately.
b) At this time the ERSIN 381 flux cored wire should be
applied to a part of the joint surface away from the
soldering iron and allowed to flow to form the joint
fillet. This will be virtually instantaneous. Do not
apply excessive solder to the joint as this will not
improve joint integrity and it will leave excess flux
residues on the surface.
c) Remove solder from the work piece and then remove
the iron tip.
This total process will be very rapid, depending upon
thermal mass, tip temperature, tip configuration and the
solderability of the surface to be joined.
