Solder Paste Products Features and Benefits End Use Applications
Lumet™ Solder Paste SAC305 Alloy
Excellent thermal cycling performance
Low voiding
Large experience base
Indoor and outdoor lighting
Automotive applications
Lumet™ Solder Paste MAXREL™ Alloy
Designed for high reliability application
High resistance to thermal cycling, vibration and creep
Ideally suited for outdoor use with high thermal cycling and vibrationconditions such as street lighting, traffic signals, automotive and
transportation lighting
Lumet™ Solder PasteSnBiAg Alloy
Low temp assembly for heat sensitive applications
Low process energy consumption
Suited for low thermal cycling load conditions such as intermittent use indoorlighting where thermal cycling tests would be between -20°C to 85°C,
and high temperature does not exceed 85°C.
Needs to be used in conjunction with a high strain absorption dielectric.
Sinter Products Features and Benefits End Use Applications
Argomax®
Die Attach Film
Superior high thermal conductivity
