Two process for
a solderable final finish.
- Chemical Tin
- Chemical Silver

Chemical
tin process UNISTAN
Process UNISTAN guaranteed
solderability during 6 months,
it gives a dense and fine grain
tin deposit. Thickness of
tin layer between 0.8 and 1.2
µm.
UNISTAN has an excellent
resistance to oxydation, which
allows him multiple passages in
REFLOW and soldering wave.
With UNISTAN the problem of the
"Whiskers" is solved.
UNISTAN contains a specific
inhibiting system which enables
him to have a high productivity
Chemical
silver process SYLVERSTAN
process SILVERSTAN guaranteed
solderability during 1 year, it
gives a dense and fine grain tin
deposit. Thickness of tin
layer between 0.2 and 0.3
um.
process SILVERSTAN is very
speed, 6 minutes cycle time .
process SILVERSTAN allows him
multiple passages in REFLOW and
soldering wave
UNISTAN SILVERSTAN
Process make it
possible to treat the printed
circuits simple and double
faces, multi-layer, flexible,
and flex-rigid, they use in
horizontal and vertical process. UNISTAN SILVERSTAN are
used to treat flexible circuits
with technology « reel to reel ». UNISTAN SILVERSTAN
are recommended for the circuits « fine line »
et « micro fine-line ».
