Ecorel Free 305-21-T5 Lead Free Solder Paste

ECOREL™ FREE 305-21 T5 is a No Clean solder paste with high performance chemistry of the ECORELTM range assuring that the assembled electronics can reach their best reliability, while exposed to challenging conditions of humidity and temperature.

  • The flux residues remaining on the PCB after soldering are chemically inert. It passes the Bono corrosion test. This is a key attribute to control the risk for electro chemical migration (ECM)
  • Low solder void percentage
  • Fine particle size distribution: the type 5 powder enhances the printing quality printing through very small stencil apertures (0201 / 01005, μBGA…
  • Less under stencil wiping is needed due to reduced smearing.
