Indium 5.7LT-1

Indalloy 303 (Bi+) Bi57/Sn42/Ag1 Low Temperature Halogen-Free No-Clean Solder Paste

Indium5.7LT-1 is an air reflow, halogen-free, no-clean solder paste designed for assembly processes using Bi-based and In-based low-temperature alloys. This paste is a clear residue product with exceptional wetting capabilities. The low activation temperature of Indium5.7LT-1, in combination with the SnBi alloys, can be especially useful as a low-temperature, Pb-free solution.

Low-temperature Pb-free solution
Outstanding printing transfer efficiency with low variation between prints
Clear post-reflow flux residue
Solder beading and solder balling minimization performance
Exceptional wetting in air and nitrogen reflow
Halogen-free per EN14582 test method

Alloys

Indium Corporation manufactures low-oxide spherical powder composed of the 58Bi/42Sn eutectic alloy in the industry standard Types 3 and 4 mesh sizes. Other non-standard mesh sizes are available upon request. The weight ratio of the flux/vehicle to the solder powder is referred to as the metal load and is typically in the range of 83-92% for standard alloy compositions.
