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

Overview: Premium Chemistry, Mass-Market Accessibility

V5 Light TF (V5L) uses the same core premium rosin-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 ROL0 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 ROL0 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 or second-guessing activation.
• Standardized Consistency: The premium rosin-based formulation delivers professional-grade consistency and flow suitable for both automated dispensing and hand soldering. (Note: For specialized, ultra-consistent flow for mission-critical automation, 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 450°C. This ensures strong, reliable solder joints that resist mechanical shock and fatigue.
• User-Friendly Rosin Base: The premium rosin-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 the industrial-level tack and flow control required by professionals, while its forgiving nature benefits 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 ROL0 Rated: Achieves the highest reliability standard for no-clean fluxes. Zero resistance without heat activation.
• Halogen-Free Compliance: Meets the strictest HX-Zero™ industry requirements, tested to EN 14582 standards.
• REACH-compliant: Made using REACH-compliant, premium raw materials.
• Genuine American Quality: Traceable origin, made in the USA, ensuring responsible manufacturing and compliance with worldwide industrial standards.

• ROL0 is a Rosin-based flux classification characterized by its very low activity level, making it suitable for high-reliability, no-clean applications. Its activated residue is not corrosive, it is halide-free (<0.05%), and it exhibits high surface insulation resistance. It passes the copper mirror breakthrough test and demonstrates low electrochemical migration (<1 decade drop).

“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™.

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!

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