STIRRI® V5-TF Light™ (V5L) - Tacky Paste Flux: The New Universal High Performance Flux

V5 Light TF (V5L): The New Universal High Performance Flux

Overview: Premium Chemistry, Mass-Market Accessibility

V5 Light TF (V5L) uses the same core premium resin-based chemistry as the ultra-high reliability V5-TF (designed for EV, UAS, and VTOL applications). The main difference is that V5 Light is processed using standard manufacturing methods and does not include the specialized AIRfree™ Technology. This accessible, volume-priced 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.
  • Standardized Consistency: The premium resin-based formulation delivers professional-grade consistency and flow suitable for both automated dispensing and hand soldering. (Note: For specialized, ultra-consistent flow, please refer to V5-TF with AIRfree™ technology).
  • 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-resistant solder joints.

Compliance and Standards

  • NC REL0 Rated: Achieves the highest reliability standard for no-clean fluxes. Zero resistance 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.
