Next-Generation Halogen-Free Tacky Flux for Hand Soldering and Rework: V5-TF (RC Sample 99g)
This high-performance, universal, no-clean, halogen-free tacky flux (V5-TF) is ideal for demanding hand soldering and rework applications, particularly in industries like aerospace and electric vehicle (EV) manufacturing. Its robust performance and environmental compliance make it suitable for critical assemblies where reliability is paramount.
Key Features & Benefits for Hand Soldering & Rework:
- Superior Wetting & Tack: The rosin-based formulation provides excellent wetting and immediate tack, crucial for efficient component placement and rework. This ensures secure component positioning during hand soldering and prevents shifting during rework processes.
- Controlled Flow & Stay-in-Place: The flux's optimized texture and controlled flow rate minimize spreading and ensure it stays in place during component placement and hot air rework, crucial for precise manual assembly. This is especially beneficial for intricate hand soldering tasks.
- Wide Temperature Compatibility: Effective fluxing action is maintained across a broad temperature range, accommodating both leaded and lead-free soldering processes. It withstands hand soldering temperatures and the higher temperatures encountered during hot air rework (up to 450°C), providing flexibility for various applications.
- Minimal Residue & No-Clean: The halogen-free, low-residue nature of the flux minimizes potential issues with electrical conductivity, insulation resistance, and contamination, simplifying the hand soldering process and reducing the need for cleaning in many cases. This is particularly important for densely populated boards where cleaning is difficult.
- Robust Solder Joints: Contributes to strong, reliable solder joints resistant to vibration and mechanical shock, essential for handheld devices and other applications subject to stress.
- Excellent for Rework: The flux's properties are maintained during hot air rework, enabling effective component removal and replacement without compromising joint integrity.
- Pleasant Scent: Improves the working environment for technicians engaged in hand soldering.
Application-Specific Considerations for Hand Soldering & Rework:
- General Electronics: Suitable for a wide range of hand soldering tasks, from general purpose electronics repair to complex assemblies.
- Aerospace & Defense: Meets stringent reliability requirements for leaded aerospace and defense applications, crucial for long-endurance, high-altitude operation.
- EV, eVTOL, HALE, UAS: Compatible with lead-free alloys used in these industries, addressing the specific challenges of high-temperature performance, vibration resistance, and compatibility with sensitive components.
- BGA Rework: The controlled flow and stay-in-place characteristics make it suitable for BGA rework, ensuring proper reflow and joint formation.
Compliance & Standards:
- Adheres to IPC J-STD-004C (Requirements for Soldering Fluxes) and other relevant IPC standards.
- Designed to meet relevant aerospace (e.g., MIL-STD) and military standards where applicable.
Formulation & Environmental Impact:
- Rosin/Halogen-Free Synthetic Resin Blend: Combines the benefits of rosin (wetting, tack) with the advantages of a halogen-free synthetic resin (electrical performance, environmental compliance).
- Low VOC (Volatile Organic Compound) content minimizes environmental impact.
- Packaged in amber tubes for a 2-year shelf life (Sample 99g currently will be packaged in clear syringes with 12 months shelf life).
Cleaning:
While V5-TF is designed as a no-clean flux, cleaning may be necessary prior to conformal coating to ensure optimal coating adhesion and long-term reliability, particularly in harsh environments. Consult with us for guidance on appropriate cleaning procedures and conformal coating materials.

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!
