Indium 8.9HF: Best all-around halogen-free solder paste

Indium 8.9HF is an industry-proven solder paste series that delivers no-clean, halogen-free solutions designed to produce low-voiding, enhanced electrical reliability, improved stability during the printing process and is ideal for miniaturized components and fine-pitch assembly. Indium 8.9HF provides first-class printing and robust reflow performance and is designed to AVOID THE VOID®.


  • Delivers excellent response-to-pause, even after being left on the stencil for 60 hours
  • Maintains excellent printing and reflow performance after remaining at room temperature for one month
  • Demonstrates consistent printing performance for up to 12 months when refrigerated
  • Resists premature flux spread to prevent surfaces from oxidizing
  • Performs with both Pb and Pb-free alloys
