Specifications Relife RL 426 soldering paste flux

• Suitable for sensors, wires, SMT components, BGA chip tinning, mobile phones and computers.
• High-purity, environmentally friendly (lead-free/halogen-free) flux paste that enhances solder fluidity and improves solder wetting.
• Effectively removes oxide film from soldering surfaces to make welding easier and to prevent oxidation.
• Leaves minimal residue, non-conductive after soldering, and generates less smoke for a cleaner repair environment.
• Strong solder joint formation—ensures “firm and strong welds” for demanding mobile repair tasks.
