    STIRRI®MtºHF-TF is a mid-temperature no-clean halogen-free synthetic REL0 soldering tacky paste flux for Tin/Lead (Sn/Pb) mid-temp assembly - Sn60Pb40, Sn62Pb36Ag2, Sn63Pb37 and similar mid-range leaded solder alloys.

    Clear flux body and clear residue make MT-HF a good choice for hand-soldering

    Contains QC-Aid™ optical tracer for instant visual contamination inspection. QC-Aid - Everyone can QC™

    Wide application range

    From hand-soldering electronics, automotive repairs, IC-chip replacement, BGA-reballing, gaming console repair to military/avionics-grade Tier halogen-free SMD solder paste.

    Performance

    Full body of enriched pine crystal rosins creating a transparent coating layer over the soldering area effectively blocking oxygen from the solder joints and thus allowing metals to bond - guaranteed!

    Traits:

    • Slightly yellow fully transparent rosin-rich flux body with clear non-corrosive residue. A truly no-clean flux - halogen-free, doesn't short components! REACH-compliant. Can be left on PCB or easily removed by hot air or basic solvents like Isopropanol.
    • Used in MT solder paste and hand-soldering electronics/automotive repairs. Smooth dispensing and flow, excellent ability to hold components in place. Easy flowing under IC chips. Universal for leaded and lead-free alloys.
    • Viscosity – 30-50 Pa/s (Malcom @ 10 RPM/25°C (x103Pa/s)) Halide-free (<0.05%). Passes BONO and SIR (Surface Insulation Resistance) test. No copper mirror breakthrough. Low electrochemical migration (<1 decade drop). 96°C-250°C temperature range.
    • Offers spectacular low-voiding and truly no-clean performance in many professional soldering areas including SMD solder paste. Best performs with mid-temp range tin/lead alloys melting at 150ºC-200ºC.
    • Contains QCAid™ - residual optical tracer glowing in UV blacklight allowing for immediate visual detection of contaminated PCB areas. QCAid - Everyone Can QC™

    SMD-Paste values:

    • Stencil life @ 30-70% RH - up to 16 hours - one of the longest values on the market allowing for a long process window and next day completion.
    • Viscosity (jars, cartridges): 100-150 Pa/s (print-grade) and 80-100 Pa/s (Dispenser-grade), Tack force: 42-44g
    • Stable wetting performance and low voiding soldering on most PCB finishes. Halogen-free clear residue. Sharp definition at high printing speeds up to 200mm/sec, enclosed print-head compatible.

    Market

    STIRRI®MT-HF compares to ALPHA® OM-6106 and Chipquik® SMD291; however, it features the QC-Aid™ optical tracer for instant visual contamination inspection, which is not offered by the market peers.

    Product Description

    Next generation REACH-compliant universal no-clean tacky paste flux for soldering electronics. Improved formula demonstrates mighty action, smooth flow from the syringe and excellent ability to hold components in place. Clear residue is fully translucent allowing unobstructed control over the soldering process. Contains QC-Aid™ optical tracer for an immediate visual contamination inspection highlighting residues in UV/blacklight. The flux has a pleasant non-chemical scent. REACH-compliant making soldering incredibly easy and fun without harming the environment or human health. 

    Complete the assembly with STIRRI HydraCoat™ conformal nano-coating. HydraCoat shields the assembly in 8 seconds. PCB continues to work even if fully submerged! 

    Strong points:

    - Industrial-grade wetting capabilities.
    - Excellent ability to hold components in place.
    - Clear residue resisting to turn brown under high-heat.
    - Not-corrosive. No-clean - can be left on PCB.
    - Slow burning ratio - long lasting.
    - QC-Aid™ for instant visual inspection of cleaning.
    - Pleasant non-chemical scent.
    - Environmentally/health friendly.

    STIRRI® is a modern prosumer product line made in the USA to satisfy demands for next generation high-end soldering chemicals.

    TACK & VISCOSITY: Contains sufficient amount of solids to stay put on the PCB - doesn’t spread over, but also not too thick - easy to clean. Holds components in-place yet allows for an easy repositioning by hot air. Smooth flow from the syringe - suitable for industrial component placement machines as well as handcraft rework and hobby use. Suspends BGA spheres creating a perfect activation environment for soldering leaded or lead-free solder balls or SMD solder paste - all-purpose flux!

    CLARITY & ODOR: Clear residue contains QC-Aid for instant PCB contamination inspection - the aid will glow in UV highlighting remaining residues for instant spot-cleaning. QC-Aid - Everyone can QC!™.  Cloud-free translucent material provides for a consistent unobstructed view of solder joints and IC pins while offering ultimate control over the soldering process and filling the air with pleasant non-chemical scent. Quick fix without fumes extractor will only make a workshop smell nice! 

    LONGEVITY & RESIDUE: Maintains stable performance under extended exposure to heat without turning into a dark gooey goop. Suitable for multi-step assembly - get back to a project a day or two later, once heated the flux will flow again without dropping performance. Dispensed in an amber syringes protecting the flux from the harms of environment extending the shelf life up to 2 years - a single tube lasts for a very long time!

    EASY SOLDERING & DESOLDERING: Implements upgraded booster for copper ions, visually noticeable while wicking the workspace regardless of the alloy leaded or lead-free. Instant action - quickly wets lead-free or leaded alloys delivering perfect shining joints. Clear residue can be easily removed by hot air, foam swab or HydraSweep Isopropanol.

    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.
