DKL EF-28 Alcohol-Resin Paste Flux
DKL EF-28 Alcohol-Resin Paste Flux delivers high performance for professional electronic soldering. This preparation contains a precise blend of 60-80% Gum Rosin (Colophony) and 15-20% Propan-2-ol. Consequently, the flux provides superior wetting for high-reliability assemblies. It cleans tinned copper surfaces effectively. Furthermore, the formula leaves non-corrosive residues that remain safe on your finished assembly.
EF-28 Performance Characteristics & Technical Benefits
The DKL EF-28 is formulated to meet the rigorous characterisation requirements of the IPC J-STD-004B standard for high-quality interconnections.
DKL engineered EF-28 for the rigorous demands of modern manufacturing. It ensures excellent solderability with legacy leaded alloys and modern lead-free options. This ROM1 classified rosin flux offers several industrial advantages:
- Superior Wetting: The flux initiates rapid action on precision copper components.
- High-Reliability Formula: Resin chemistry produces stable, non-corrosive residues. These residues protect long-term board performance.
- Versatile Compatibility: It supports leaded alloys like Sn60/Pb40. Additionally, it works perfectly with lead-free alternatives like SN100C®.
- No-Clean Efficiency: Most users treat this as a no-clean paste flux. However, you can remove residues easily with isopropyl alcohol for coating preparation.
Application Methods for EF-28 Alcohol-Resin Paste Flux
Apply EF-28 flux paste using a brush or dipping method. Solder the components immediately with a standard iron or induction heat. Afterwards, the flux cools into a hard, protective barrier. Therefore, you do not need to perform post-process cleaning in standard environments.
EF-28 Paste Flux Format Availability:
- Standard Stock: We supply 500g and 1kg industrial containers.
- Bulk Supply: Custom large-volume sizes are available upon request.
- Physical State: The stable paste features a faint, non-pungent odour.
Health, Safety & Compliance
Always follow standard workshop safety protocols when handling this flammable flux. Wear appropriate eye and skin protection. Moreover, you must ensure the workspace has adequate fume extraction. Soldering fumes can irritate the respiratory system. For this reason, avoid prolonged exposure.
