Water Soluble Fluxes
Amerway 725 VOC Free O.A. Flux -- Amerway 725 is an organic acid activated water soluble flux formulated to conform to a VOC Free environment. This flux has high activity level for wave soldering or lead dipping and can be completely cleaned with water or a combination of water and detergent. The Amerway 725 has excellent solder wetting characteristics on a wide variety of metal surfaces.
Application: Amerway 725 flux can be applied by wave, spray or foam fluxing equipment. The flux application and reservoir tanks should be made of plastic or titanium. Best results can be obtained with the following guidelines:
A. Keep the wave height or pot level through appropriate adjustments.
B. Replace flux daily if self-contained storage container is not available; otherwise replace after every forty hours of operation.
C. Adjust the specific gravity to the nominal level by using a hydrometer. Evaporation volume can be replenished with the addition of de-ionized water.
D. Add flux to maintain the appropriate level.
E. Clean fluxing equipment regularly to remove debris which may come from the printed circuit boards.
F. When wave fluxing, it is recommended that a air knife be used at the exit of the wave fluxer.
G. An increase in preheat topside temperature may be necessary to evaporate the water from the flux and eliminate spatter at the solder pot which could produce solder balls.
Benefits: Amerway 725 VOC Free Organic Acid Water Soluble Flux has excellent wetting characteristics on a wide variety of metallic surfaces which will reduce icicling and bridging problems. Its wetting and penetrating ability leave shiny solder connections on even heavily oxidized surfaces, as well as brass and tin-nickel surfaces. This VOC free flux is water cleanable and can provide cost savings through enhanced process control as well as a safer work environment.
- No-flammable.
- Cleans to a high standard.
- Use water as thinner.
- Increase line speed.
- Reduction in defect rates.
- Reduction of dross on solder pot.
Residue Considerations: As with all organic acid halide activated fluxes, printed circuit boards must be thoroughly cleaned as soon as possible to prevent the possibility of corrosion and electomingration. Any delays can also cause solder joints to discolor. In line washers are recommended when using the Amerway 725 flux. When a batch washer is used, a pre-soak is recommended with a wash acid such as Amerway 900 Emviro-Clean-25 to minimize washing difficulties when a batch of boards is being accumulated. Amerway 725 cleans effectively in water with a minimum temperature of 120 F or higher. Water quality is the largest consideration in water wash system and care must be taken to utilize wetting agents or neutralizers where needed or proper cleaning will not occur.
