FUCHS TIMs thermal interface materials are engineered to efficiently dissipate heat, ensuring reliable, safe, and optimized performance of electronic components. TIMs fill the air gap between heat-generating components, like chips or PCBs, and heat-dissipating surfaces, such as heat sinks or chassis. High thermal conductivity enables efficient heat transfer and rapid dissipation from critical hot spots, enhancing device performance and reliability.
Unlocking the Benefits of FUCHS TIMs
FUCHS TIMS are recommended for electronic applications requiring heat dissipation across a wide range of industries, including Automotive, Data Centers, Consumer Electronics, Telecommunications, Semiconductor, and Defense. Typical applications include CPUs and GPUs, data storage modules, ADAS control systems, electronic control units, power electronics such as MOSFETs and IGBTs, as well as various consumer electronic devices.
FUCHS TIMs offers several performance benefits including:
Excellent Thermal Conductivity
High Dielectric Strength
High Temperature Stability
Wide Compatibility
Silicone-Free
Easy Dispensing
Which TIMs is Right for You?
Selecting the right thermal interface material is critical to ensuring optimal reliability and efficiency in your application. Here are some key factors to consider:

Reworkability
Greases and putties allow easy removal while epoxies and potting compounds are permanent.

Mechanical Stability
Putty and liquid gap fillers are soft and forgiving whereas epoxies introduce stress on sensitive components.

Automation Compatibility
All types of TIMs except pads support automated dispensing. Pads are ideal for manual, repeatable assembly lines.

Contamination Sensitivity
Silicone-based TIMs can outgas and form films that reduce adhesion, and affect coating quality. Non-silicone materials offer low outgassing to protect sensitive electronics, optics, and cleanroom applications.
