Upgrade your soldering results with the 2UUL SC19 Mr. Flux 100, a professional-grade 100g soldering flux paste specially formulated for precise PCB repair and micro-soldering. Trusted by mobile phone technicians and electronics repair centers, this high-performance flux delivers excellent solder wetting, strong joint formation, and reliable performance on delicate boards.

The advanced anti-oxidation formula effectively removes and prevents oxidation on pads and components, ensuring smooth solder flow and minimizing common defects such as cold joints or incomplete wetting. Its smooth, stable, high-viscosity consistency applies easily with a syringe or tool, stays in place without running or splattering under heat, and leaves minimal residue thanks to its no-clean / low-residue formula—reducing post-solder cleanup time.

Ideal for everyday workshop use, the generous 100g pack is perfect for IC reballing, BGA chip repair, SMD soldering, jumper work, and full motherboard rework on smartphones, tablets, and other electronics. Compatible with both leaded and lead-free solder.
