HandcraftUHF-TF is a first-hand alternative to the low-cost fluxes of unknown origin - a mass-market disruptor and a flagship formulation dedicated to soldering professionals and hobbyists alike.


Hand-soldering electronics, automotive repairs, IC-chip replacement, BGA-reballing, gaming console repair, halogen-free SMD solder paste.


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!


  • 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.
  • Designed for 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 (x103mPa/s)) Halide-free (<0.05%). Passes 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 @ 30-45% RH - up to 18 hours - one of thelongestvalues on the marketallowing for a long process windowand next day completion.
  • Viscosity (jars, cartridges): 110-160 Pa. s (Print-grade) and 80-120 Pa. s (Dispenser-grade),Tack value: 43-45g
  • Stable wetting performance and low voiding soldering on most PCB finishes. Halogen-free clear residue.Sharp definition at high printing speeds up to 100mm/sec, enclosed printhead compatible.
