Amerway #300 Rosin Flux-RA-25 Technical Data Bulletin
Technical Data Sheet
| Description: |
| Amerway 300 Rosin Flux-RA-25 is specially formulated with a pure water-white rosin in
alcohol and is considerably stronger and more active than the Type RMA fluxes. For
High reliability, flux residues should be removed from printed circuit after soldering with
Amerway 900 Enviro-Clean-25 Detergent and Saponifier or solvent. Amerway 300-RA-
25 meets the Joint Industry Standard J-STD-004, flux Type M-1. |
| Application: |
| Amerway 300 Rosin flux RA-25 was formulated for use with foam, wave, dipping, spray
or brushing application. Although there are no standard operating instructions due to the
variety of equipment for foaming, the following guidelines will help assure dependable
soldering. |
| |
-Maintain a constant level in the flux tank. |
| |
-Evaporation losses should be compensated by using Amerway 305 RA Thinner. |
| |
-Keep equipment clean and avoid contamination, particularly oil and water. |
| |
-Keep the air pressure low and make sure the air lines contain traps to remove
moisture and oil wick could change the foaming properties of the flux. |
| Benefits: |
|
| |
-Provides excellent solderability with difficult to solder printed circuit boards. |
| |
-Excellent wetting and capillary action. |
| |
-Clean white rosin ensures clean solder joints. |
| |
-Fast recovery of foam column. |
| |
-Conforms to the requirement of J-STD-004. |
