Handcraft-UHF-TF™ is a universal no-clean halogen-free soldering tacky paste flux

Clear flux body and clear residue make it fantastic choice for hand-soldering

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

Wide application range

Top-tier aerospace & defense grade material can be safely used for hand-soldering electronics, automotive repairs, IC-chip replacement, BGA-reballing, gaming console repair, applications requiring halogen-free no-clean clear residue with incredibly low voiding.

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 (x10'3Pa/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 @ 30-70% 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 value: 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.
