V5-TF – Universal Air-Free No-Clean Halogen-Free Soldering Tacky Flux for Advanced Electronics (ROL0)

V5-TF: Next-Generation Air-Free & Halogen-Free Flux

Overview: Six-Sigma Consistency for Demanding Electronics

V5-TF is the ultra-high reliability, premium edition of our V5 rosin chemistry, specifically engineered for critical industrial applications like aerospace (eVTOL, FPV, HALE, UAS) and electric vehicle (EV) manufacturing. It utilizes our proprietary AIRfree™ Core Technology, a consolidated manufacturing process that removes microscopic air bubbles common in conventional fluxes. This unique approach ensures six-sigma consistency and uninterrupted flow, which is vital for high-precision metered automated conveyor dispensing and achieving superior solder joint integrity in demanding environments.

Key Features & Benefits (The AIRfree™ Advantage)

Feature	V5-TF Advantage	Significance for Critical Assemblies
AIRfree™ Core Technology	Provides a highly homogenous paste with virtually no microscopic air bubbles.	Dispensing Reliability: Guarantees uninterrupted flow, eliminating splatter and inconsistent dispensing issues.
Six-Sigma Consistency	The highest level of material quality assurance available in flux paste.	Yield & Quality: Ensures extremely low voiding rates and repeatable performance for mission-critical systems.
QC-Aid™ Tracers	Includes Optical UV-Tracer and Olfactory Tracer.	Contamination Control: Facilitates instant detection of residues for cleaning inspection. Also used to detect contamination on tools, containers, dispensing equipment, flushed lines, workbenches, gloves, and garments to prevent cross-contamination.
Premium V5 Rosin	Superior NC ROL0 True No-Clean rosin-based formulation.	High Reliability: Residues are inert and non-conductive, simplifying processes in complex, high-density PCBs.
Thermal Stability	Maintains robust activity across a wide range (up to 450°C).	Robustness: Ensures strong solder joints resistant to vibration and mechanical shock.

Typical Applications

Industry / Category	Specific Use Case
Aerospace & Defense	Manufacturing of eVTOL systems, HALE platforms, and high-performance FPV/UAS components requiring high-vibration resistance.
EV & Industrial Automation	Mass production lines using high-speed metered conveyor dispensing where air pockets cause costly line stoppages.
Advanced Rework	Precision BGA/aBGA reballing, hot-air rework (up to 450°C), and mission-critical hand-soldering.

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 for total Halogen content.
• REACH-compliant: Made using REACH-compliant, premium raw materials.

• 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.
