This special no-clean flux volatilizes (vaporizes) at soldering leaving minimal clear residue which may
be removed with HOT water if desired.
Qualitek Silver Solder
These solders are specially formulated to be
used with gold and silver plated contacts to
prevent the leaching of precious metals which
is easily dissolved into tin. Leaching is the ten-
dency for tin/ lead-bearing solder to dissolve
metallizations during reflow operations. The
rate at which silver leaches into molten tin/ lead
solder alloy is retarded by using solder alloys
which contain a small amount of silver. These
solders contain 2% silver in the alloy.

Qualitek Lead-Free Solder
Environmentally safe solder. This solder is designed to
replace the standard lead barring type of solder for plumb-
ing applications. The reflow temperature is 221 o - 230 o C.
The alloy is 96.5% Tin (Sn) / 3.5 % Silver (Ag). This com-
bination is the best for soldering plumbing or similar con-
nections where excess heat will not destroy components. It
has excellent wetting and spreading properties.
