REWORK FLUXES
Multifix 425-01 and 450-01 are tacky fluxes designed for use in a wide range of electronics assembly and rework processes. They represent a range of activities and residue levels to meet different customer requirements.
- No Clean Formulations
- Low residue
- Range of activity to deal with different component solderability
- Halide free
- Suitable for dispensing
- Compatible with solder coatings and/or No Clean flux cored solder wire product range
Both products are supplied in syringes or cartridges for application by dispensing. The user should select the product most appropriate to the application.
Multifix 450-01 leaves visible but clear residues that do not require cleaning. It has good activity for rework operations.
Multifix 425-01 is less active. However, the residues are clear and barely visible while soldering activity is still sufficient for many users.
