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

10x increased reliability when comparedto solders

High shear strength

Controlled, uniform bond line thickness

No Voids

Argomax® (once processed) is pure silver, with a much higher melting point than solders. Argomax® is ideal for ultra high power,

high performance LEDs

Fortibond™ Pressureless Sinterable Paste

High thermal conductivity

High reliability

Ultra low voiding

High Shear Strength

Fortibond™ is well suited for both indoor and outdoor lighting applications that use high power LEDs due to the material’s high thermal

conductivity and reliability

Conductive Epoxy Features and Benefits End Use Applications

Atrox™ Conductive Epoxy

Silver filled epoxy is tailored for LED applications

Low Voiding

Low temp and low modulus versions

Enables a thin bond line

Atrox™ is designed for low to mid power LEDs, applications such as displays,indicators, signals and various small consumer electronics and multi-chip

LED lighting packages
