Flexsol 903 is a rosin based, absolutely
halogen free, no-clean solder wire.
Flexsol 903 is designed
to minimize spattering during soldering.
It wets faster and spreads
more than similar products, even with SnCu alloys.
Total
soldering times close to those
of the SnPb alloys.
Flux
content 2,2% or 3,5%.
Flexsol 903 key features include: very
low spattering halide
free: (0.00% halides) prolongs
solder tip life 3
flux channels suited
for automatic (robotic) soldering
Available alloys are:
SAC305
SnCu0,7
Application
The Flexsol 903
should be applied
slightly to the
point where component,
pad and soldering
tip meet.
Add subsequently,
without interrupting
the heat supply,
the correct amount
of solder.
Recommended
soldering tip temperature
setting is 320°C-360°C
(625°F-680°F)
when
soldering
of more
dense
materials
is required
(Ni,Zn,…),
a temperature
up to
420°C
(790°F)
is allowed.
