The Relife HW11 Lead-Free and Halogen-Free Solder Flux is a high-performance, environmentally friendly soldering flux paste engineered for precision micro-soldering, computer motherboard CPU servicing, and mobile phone chip repair. Formulated with a lead-free and halogen-free composition, HW11 meets modern safety standards while operating with minimal smoke emission and no irritating odor.

Featuring a nano high-activity factor, Relife HW11 quickly removes the oxide film from welding surfaces to ensure effortless soldering, superior surface wetting, and optimal joint adhesion. Its enhanced fluidity and non-corrosive, environmentally friendly solder-resist rosin allow the flux to spread evenly across fine-pitch components, preventing oxidation and avoiding cold soldering defects. Packaged in an accurate syringe injection tube with application tips, it enables precise, one-handed dispensing with zero waste. The no-clean formula leaves minimal, non-conductive residue to reduce post-cleaning effort and deliver bright, full, and uniform solder joints.

Key Features

1. Lead-Free & Halogen-Free Formula: Adheres to modern environmental standards for a safer workbench with minimal smoke and no irritating odor.
2. Nano High-Activity Factor: Rapidly breaks down surface oxide films to prevent cold soldering and ensure strong, reliable solder bonds.
3. Enhanced Fluidity & High Tackiness: Spreads evenly across micro-soldering points and fine-pitch components without slumping or bleeding.
4. No-Clean Minimal Residue: Leaves clear, non-conductive residue after reflow, reducing post-soldering cleanup time and short-circuit risks.
5. Syringe Injection Dispensing: Enables precise, zero-waste application and effortless one-handed metering directly on PCB pads.
6. Bright & Uniform Solder Joints: Enhances solder wetting performance to produce full, bright, and durable connections.
