Performance Advantages and Applications
The activity level and residue characteristics of Kester 1544 Flux are directly governed by its solid percentage concentration. This formula is specifically developed for critical soldering conditions where standard or non-activated options fall short. Key functional benefits include:
- High Activation Level: Designed for applications where non-activated (R) and mildly activated (RMA) rosin fluxes lack sufficient strength to remove heavy metal oxides.
- Corrosion Prevention: Serves as an ideal alternative when complete removal of potentially corrosive, water-soluble organic acid flux residues is not feasible.
- Superior Surface Wetting: Enables instant wetting and excellent capillary action across intricate electronic assemblies.
- Solder Coating Compatibility: Highly suited for lead-tinning, solder coating bare metal leads, and precision circuit soldering.
Operational Characteristics
By blending pure Grade WW rosin with optimized organic activators, Kester 1544 Flux ensures rapid oxide removal without compromising the long-term electrical integrity of sensitive assemblies under proper process parameters.
