Relife RL-422S-IM Halogen Free Flux Paste with Push & Needles - 10cc

RL-422S-IM Professional Halogen-Free Flux for BGA & Micro Soldering

In motherboard repair, poor-quality flux causes weak solder joints, oxidation, bridging, and difficult rework. Many ordinary flux pastes leave heavy residue, corrode pads, or produce unstable solder flow during BGA reballing. The Relife RL-422S-IM Halogen Free Flux Paste is designed to deliver clean, smooth, and stable soldering performance for precision PCB work. Its halogen-free formula reduces corrosion risk while ensuring even solder flow and bright, reliable joints. With optimized viscosity and syringe control design, this flux supports accurate application in micro soldering, BGA rework, IC repair, and fine-pitch component installation. Technicians prefer RL-422S-IM because it improves solder wetting, reduces residue issues, and enhances overall repair reliability.
