    V5-Light-TF (V5L): The New Universal Air-Free Soldering Standard

    V5 Light (V5L) is the market version of the ultra-high reliability tacky flux V5-TF, engineered with the same revolutionary AIRfree™ V5 core technology. American-made, premium resin-based tacky paste flux guarantees NC REL0 True No-Clean performance and industrial-grade consistency, priced affordably to bring the most recent advancement in soldering chemistry to every bench. It is the perfect universal solution for rework, BGA, and all machined or hand soldering, offering superior quality and Halogen-Free compliance as the clear winning alternative to imported fluxes.

    Key Highlights:

    • Derived from V5-TF: Accessible market "light" version of the V5-TF tacky flux, designed for demanding EV, UAS, and VTOL assemblies.
    • NC REL0 True No-Clean: Maximum reliability, benign residues.
    • AIRfree™ V5 Core: Professional-grade consistency and uninterrupted flow soldering without splatter.
    • Priced for Volume: Premium resin enhanced in high volumes to achieve mass market affordability to compete with low cost imports without sacrificing quality.
    • Universal Utility: Excellent for Rework, BGA, Machined and Hand Soldering.
    • Genuine American Quality: Traceable origin, made in the USA - a piece of technology that make American products stand out and dominate on product shelves around the world.
    • REACH-compliant: Made with attention to European chemical regulations, does not contain SVHC-restricted substances.

    Product Description

    Premium Performance, Mass-Market Accessibility

    V5 Light TF (V5L) is the market version of the ultra-high reliability V5-TF, designed for EV, UAS, and VTOL applications, engineered with the same revolutionary AIRfree™ V5 core technology. The main difference is V5 Light does not contain visual or olfactory QC tracers present in V5. American-made, premium resin-based tacky paste flux guarantees NC REL0 True No-Clean performance and professional consistency, priced affordably to bring advanced industrial soldering to every bench. It is the perfect universal solution for rework, BGA, and all machined or hand soldering, offering superior quality and Halogen-Free compliance as the clear alternative to imported low-cost fluxes.

    Key Performance Advantages

    • NC REL0 True No-Clean Reliability: Provides maximum electrical reliability. Residues are benign, inert, and non-conductive, simplifying your process by eliminating the need for mandatory cleaning for most applications or second-guess.
    • Air-Free Technology & Consistency: The proprietary AIRfree™ formulation ensures a highly homogenous, almost clear paste, free of microscopic bubbles, delivering professional-grade consistency and uninterrupted flow for both automated dispensing and hand soldering without splatter.
    • Broad Process Window: Highly forgiving and versatile, maintaining robust fluxing action across a wide range of component sizes, surface finishes, and temperatures.
    • Thermal Stability: Engineered to withstand peak reflow temperatures and maintain activity during hot air rework procedures, effective up to 450ºC. This ensures strong, reliable solder joints that resist mechanical shock and fatigue.
    • User-Friendly Resin Base: The premium resin-based formulation delivers excellent wetting and tack, while contributing to low residue levels that minimize issues with electrical conductivity and contamination.

    Application-Specific Design Considerations

    • Universal Utility: The volume-priced formulation is highly effective for a wide market range, including Rework, BGA Reballing, Machine Dispensing, and General Hand Soldering.
    • Professional and Novice Use: Designed for industrial-level tack and flow control required by professionals, while its forgiving nature and broad process window benefit beginners and hobbyists.
    • Alloy Compatibility: Exhibits excellent compatibility with a wide range of solder alloys, including common SnAgCu and traditional SnPb alloys.
    • Rework & Component Replacement: Maintains stability and activity during hot-air rework, contributing to strong, vibration and drop-resistant solder joints.

    Compliance and Standards

    • NC REL0 Rated: Achieves the highest reliability standard for no-clean fluxes. Zero resistance "out of the box" without heat activation eliminates second-guessing if the flux has been activated sufficiently to become no-clean.
    • Halogen-Free Compliance: Meets the strictest industry requirements for environmental safety and long-term reliability.
    • REACH-compliant: Made with attention to European chemical regulations, does not contain SVHC-restricted substances.
    • Genuine American Quality: Traceable origin, made in the USA, ensuring responsible manufacturing and compliance to worldwide industrial standards.

    Cleaning "No-Clean"

    “No-clean” indicates cleaning method as defined by IPC standard and does not mean that the flux leaves no residue. No-clean rather means that the flux can be left on PCB for several consecutive SMT assemblies but also won’t cause corrosion if left indefinitely. However, cleaning can be necessary and it is desirable. No-clean fluxes are easily removed using industrial solvents in ultrasonic devices or using commercially available flux residue removers like STIRRI HydraSweep™.

    Dispensing Kit

    This product does not include any Dispensing Kit - a separate purchase! 

    Dispensing Kit is an add-on for manual dispensing, used to create a pressure with a plunger similarly to a medical syringe.

    Air syringes intended for pneumatic dispensing machines use a piston stopper instead of a plunger. Do not remove the piston as it delivers the best seal preventing contact with air!

    Compliance

    This material is certified REACH-compliant - does not use any raw materials from the REACH restricted list of substances of high concern.
