Description
HI-GRADE AO-20-S is a white powder
formulated to reduce and prevent the oxides of solder, commonly know as dross, on still
pots and wave solder machines. Many competitive dross reducing materials are base on
mineral oils and fatty acid compounds that breakdown and deposit on the PCB assemblies.
AO-20-S is a stable, none fuming and high melting compound with no flash or fire points.
No smoke or fumes are generated when solder pot temperatures are below 250 deg. C. In
addition, it contains no halides which can corrode electronic assemblies.
Uses
Move dross into one area of solder bath
using spatula or knife blade. Solder pot temperature should be 230 - 250 deg. C
Apply AO-20-S directly over the dross. The amount to be applied depends on the area to be
covered.
Approximately 5 - 10 seconds after applying chopped powder unto the solder pot, the
recovery of dross from the solder begins. Continue working with the remaining dross.
Remove dirt and other materials form the pot after completion.
