Estimated reading time: Less than a minute

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

Indium5.7LT-1 is halogen-free per EN14582 test method. It joins Indium Corporation’s versatile high-performance, low-voiding solder pastes designed to accommodate a variety of industry requirements with lead-free, halogen-free, and no-clean options.
