Indium Launches Water-Soluble, Halogen-Free Solder Paste


Reading time ( words)

Indium Corporation has released Indium6.6HF Solder Paste—a new water-soluble solder paste that is compatible with both SnPb and Pb-free alloys. Indium6.6HF is designed to provide exceptional stencil printing performance and minimize voiding in PCB assembly applications.

Indium6.6HF exhibits superior wetting to a variety of surface finishes resulting in the fewest voids, a reduction in the size of the largest voids, and minimized overall voiding.

Other Indium6.6HF benefits include:

 - Halogen-free per IEC 61249-2-21 test method EN14582

 - Exceptional printing process window:

  • High transfer efficiency
  • Long stencil life (up to 12 hours)
  • Excellent response-to-pause
  • Prints consistently at a wide range of speeds

 - High tack value (>8 hours) ensures consistent component holding power, allowing high-speed component placement operation

 - Cleanable up to at least 72 hours after reflow
