Thermally Conductive Adhesive
Thermally Conductive Adhesive TIA350R
TIA350R is a one-component, heat curable silicone adhesive designed for thermally conductive applications. TIA350R cures quickly upon exposure to heat, and adheres well to a wide variety of substrates.
Key Features
- Good thermal conductivity
- Low temperature, fast cure
- Easy to use one component formulation
- Electrically insulative
- Primerless adhesion to many substrates
- Non-corrosive to metals
Applications
- Thermal Interface Material between dies and heat spreaders
- Adhesive for use between various heat sources and heat dissipation devices.

Potential Uses
Thermal Interface Materials materials provide a heat path from a heat source to a heat dissipation device. Thermal Interface Materials are used in almost all Electronic Products to
- Remove heat,
- Maintain device processing speed / functionality,
- Extend the lifetime of electronic products.
Inside the package
- Thermal path between Si & heat spreader
- Requires structural adhesion
- Ability to withstand thermal stress
Outside the package
- Thermal path between heat spreader/ Sink
- Reparability commonly required
Testing of TIA 350R Thermally Conductive Adhesive
- TIA350R is a self leveling material with a thixo index (1 1/s / 10 1/s ) at 20 degrees C
- TIA350R shows a shear thinning effect when pumped
- Storage test
- Material shows a slight increase in viscosity after 14d @ RT
- Material can not be stored at 40°C
- Storage at RT does not show a significant impact on hardness
- Material can also be cured at lower temperatures (extended cure time might be required)
- Reliability data
- Material shows some changes in mechanical properties after aging
- Tensile Strength increased at higher temperatures (more force is needed to break the silicone), while the elongation is only slightly impacted (material still flexible)
- Almost no change in hardness at higher temperatures
- Useful Temperature Range: -40°C to 200°C
