Indium Corporation has released a new low-temperature solder paste specifically developed to minimize solder beading and solder balling. Indium5.7LT-1 is an air reflow, halogen-free, no-clean solder paste designed for low-temperature assembly processes using indium and bismuth alloys.

Indium 5.7LT-1 is engineered with a balanced set of properties for outstanding printing and soldering, including:

  • Low-temperature reflow
  • Clear post-reflow flux residue
  • High transfer efficiency and low variation
  • Excellent response-to-pause
  • Low-voiding in bottom termination components (QFNs), BGAs, LGAs
  • Excellent wetting
