Ecofrec™ TF 37

  Technical Data Sheet     Safety Data Sheet   ECOFREC™ TF37 & ECOFREC™ TF37I are tacky flux designed for soldering and rework of traditional components and SMDs. Tacky fluxes ECOFREC™ TF37 & ECOFREC™ TF37I allow metal-free soldering of SMDs on PCBs, the PCBs' solder pads being covered by about 100 microns of metal solid solder deposit (SSD technology such as SIPAD etc). Designed for this technology, ECOFREC™ TF37 & ECOFREC™ TF37I exhibit good printing behavior. Specifications Color Amber Solubility In water: Not soluble In alcohol: Soluble Classification according ANSI/J-STD-004 ROL0 Halogen % 0 Density at 20°C 1 Viscosity at 20°C Pa.s  (Measured on BROOKFIELD RVT viscosimeter with Mobile F HELIPATH system, at 5 rpm) 300 - 500 Characteristics Tacky Fluxes ECOFREC™ TF37 & ECOFREC™ TF37 are high viscosity fluxes made of complex blending of resins, activators and solvents. After soldering, flux residues remaining on the PCB are non-aggressive and not l
