RELIFE RL-UV424 FLUX PASTE (10ML)

Description

The RELIFE RL-UV424 Halogen-Free No-Clean Flux Paste is a premium, high-activity soldering flux engineered specifically for advanced smartphone, laptop, and gaming console logic board repairs. Formulated to meet the strict demands of chip-level micro-soldering, this syringe-loaded flux paste is completely free of toxic halogens, ensuring a safer workspace and preventing the long-term corrosion of delicate copper traces.

Featuring an advanced “No-Clean” chemical profile, the RL-UV424 exhibits exceptional wetting properties, allowing lead-free solder alloys to flow smoothly and form brilliant, uniform, and mechanically strong solder spheres. It leaves behind a minimal, transparent, and non-conductive residue that requires no post-solder washing, drastically speeding up your bench workflow.

Key Features & Bench Advantages:

• 100% Halogen-Free Formulation: Eliminates aggressive chemical compounds, significantly reducing irritating fumes and protecting delicate multi-layered PCB substrates from long-term acid corrosion.
• Superior Wetting & High Activity: Accelerates heat transfer and effortlessly breaks down tough surface oxidation, ensuring perfect surface tension for smooth BGA reballing.
• No-Clean Transparent Residue: Leaves behind an ultra-clear, non-sticky, and highly insulated residue layer that won’t bridge pins, look messy, or discolor the motherboard.
• Anti-Oxidation Shielding: Forms a resilient protective barrier over copper pads during high-temperature reflow cycles, preventing pad darkening and cold solder joints.
• Syringe Dispenser Convenience: Packaged in a professional syringe plunger tube for precise, mess-free micro-droplet application directly onto dense smartphone CPU, RAM, and Power IC matrices.

Technical Specification Matrix

Recommended Bench Application:

1. For BGA Reballing: Apply a tiny bead of RL-UV424 over the clean IC pads before dropping your solder balls or applying solder paste. Its high tackiness keeps the micro-spheres perfectly aligned as they transition into molten spheres under your hot air gun.
2. For Drag Soldering: Apply a thin line across dense connector pins (like FPC battery or screen sockets) to guide your soldering iron tip seamlessly, eliminating bridge shorts on the first pass.
