Ecorel™ HT 301T

  • Pb93,5Sn5Ag1,5 Leaded solder paste
  • No clean printing process
  • Low voids & high reliability

ECOREL HT 301T is a No-Clean solder paste with high lead content (Pb93,5Sn5Ag1,5), designed for power semiconductors and high temperature assembly of micromodules and embedded systems. Formulated in order to achieve very low levels of voiding, especially for power components (QFN, DPAK, etc.) and to remove easily the flux residues when post reflow cleaning is required.



  • Low void level to improve heat dissipation
  • Very good wetting on NiAu, Ni, NiP, and Cu lead frames
  • Easy-to-clean flux residues


  • Increase lifetime and reliability of your product, hence reduces risk of premature failures.
  • Fast paste-printing speed


  • No CMR containing substances
  • No Halogen
