HI-GRADE #3590-10 NO-RESIDUE FLUX
Description
Hi-Grade #3590-10 No Residue Flux is a
specially formulated low solids, non-halide, rosin/resin-free flux designed for soldering
where the cleaning operations are to be eliminated. This flux contains very effective flux
activators which result in better solderability and lower defects.
Benefits
- Meets Bellcore Specifications TR-NWT-000078
- Boards properly fluxed and soldered will pass MIL-D-28809
without cleaning
- Increased acid value results in better solderability and
lower defects
- Compatible with conformal coatings
Application And Uses
The Hi-Grade #3590-10 can be applied
by foam, wave, spray or by dipping. The following suggestions will help improve the
foaming characteristics:
- Narrow flux chimney
- Use dual stones
- Add brushes inside flux chimney
- Maintain proper flux level
- Clean foam fluxing stone regularly
- Maintain specific gravity or acid value with #16-3000
Thinner
The Hi-Grade #3590-10 can used successfully
in all types of spray fluxes. It can be used very effectively in single or dual wave
soldering configurations. Assemblies with surface mount, through-hole and mixed technology
boards can all be soldered successfully.
The Hi-Grade #3590-10 can be used
successfully with all solderability preservative coatings, including hot air leveled,
roll-tinned, infrared fused, rosin based lacquers and organic solderability protective
coatings.

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.
