Product Overview
Reflow Peak Temperature Below 220°C
With lower process temperatures compared to traditional lead-free alloys, Indalloy®301LT prevents thermal defects such as warpage or delamination within electronics packaging.
Solid Thermal Performance
For temperature-sensitive thermal interface applications, Indalloy®301LT enables soldering as an alternative to leverage the high thermal conductivity of a metals-based solution compared to conventional organic TIMs.
Lead-Free and Bismuth-Free
Future-proof, ROHS-compliant technology with robust mechanical properties enables low-temperature soldering without sacrificing reliability compared to traditional bismuth-containing alloys.
Reliability Delivered
Tested against AQG-324 for automotive power electronics, Indalloy®301LT offers reliable performance in applications that must balance mission profile demands and processing temperatures.
