HI-GRADE #2212 MILDLY ACTIVATED (RMA)
ROSIN FLUX
Description
HI-GRADE #2212 ROSIN FLUX is a specially
formulated rosin mildly activated foam flux designed to prevent "white residue"
formation.
This flux contains a specially blended
solvent system to go along with its exceptionally pure rosin base, which provides very
effective fluxing and greater insulation resistance.
Components in the solvent system are of
high purity and the unique blending of solvents keeps evaporation losses to a minimum.
HI-GRADE #2212 ROSIN, FLUX is laboratory
tested (both raw materials and finished product) under strict quality control for
consistent composition and performance.
HI-GRADE #2212 ROSIN FLUX meets MIL-F-14256
specification covering liquid mildly activated rosin fluxes.
Uses
HI-GRADE #2212 ROSIN FLUX is especially
formulated for fast, efficient foam fluxing of printed circuit boards and other electronic
assemblies.
Advantages
HI-GRADE #2212 ROSIN FLUX has many special
characteristics - among them are:
1) Flux formulation virtually eliminates
unsightly white residues.
2) Excellent capillary action.
3) Fast recovery of foam column.
4) Instant wetting.
5) Minimal evaporation losses.
Applications
HI-GRADE #2212 ROSIN FLUX is formulated for
use with foam flux operations, but can also be applied by dipping, brushing or spraying.
Although there are no uniform working instructions because of the variety of foam fluxing
equipment on the market, the following guidelines will help assure dependable solder
joints:
1. Maintain adequate and constant flux
level in the fluxing unit.
2. Evaporation losses should be compensated by using HI-GRADE #16-2212 ROSIN FLUX THINNER.
3. Keep equipment clean and avoid contamination, particularly, oil and water.
4. Keep the air pressure low and make sure the air lines contain traps to remove water and
oils which may change the foaming properties of the flux.
Residue
The residue is considered non-hygroscopic,
non-tacky and can be easily removed with Hi-Grade rosin residue removers. Alcohol and
chlorinated solvents will also remove the residue, but at a reduced rate. It is suggested
when to remove all undecomposed flux to attain high reliability.

Safety And Precautions
All fluxes with low flash points should be
handled with utmost care and precaution. They should stored in a dry, well-ventilated area
and flames, sparks and direct heating should be avoided.
