Thermal Interface Materials

Electronic devices and systems continue to be designed to run at increasingly higher clock speeds while at the same time being reduced in size. As a result Thermal Management becomes more important to the functionality of a product. To increase heat dissipation between a hot area and the cooling device such as a heat sink, THERMAWORX Thermal Interface Materials are used. These silicone based materials work by displacing the air in uneven areas with highly conductive material yielding increased cooling. Thermal Interface Materials offer excellent thermal transfer properties across a wide gap range, and are available in several formulations for use in a variety of thermal management scenarios.

Welcome to 3G Shielding's Thermal Catalog, where we present our range of advanced thermal management solutions. In this section, we focus on the revolutionary Thermal Gap Pads, an essential component in efficiently transferring heat away from critical electronic devices. These high-performance thermal gap pads are designed to bridge the gaps between heat-generating components and heat sinks, ensuring optimal heat dissipation and prolonged device reliability.

What are Thermal Gap Pads?

Thermal gap pads are soft, compressible thermal interface materials (TIMs) designed to fill gaps and irregularities between electronic components and heat sinks. They provide efficient heat conduction by eliminating air gaps, thereby facilitating the transfer of heat away from the source to the sink. Thermal gap pads come in various formulations, thicknesses, and thermal conductivities, making them suitable for a wide range of applications.

Key Benefits of 3G Shielding's Thermal Gap Pads:

  • Superior Thermal Conductivity: Our thermal gap pads boast high thermal conductivity, allowing for effective heat dissipation. With low thermal resistance, they minimize the risk of overheating and ensure optimum performance of your electronic devices.
  • Even and Uniform Thermal Interface: The soft and conformable nature of our gap pads ensures complete contact with irregular surfaces, creating an even and uniform thermal interface. This minimizes the presence of air gaps, a common issue with rigid TIMs, and enhances the overall thermal performance.
  • Electrical Insulation: To prevent electrical short circuits and EMI (Electromagnetic Interference), our thermal gap pads offer excellent electrical insulation properties. This ensures safe and reliable operation, especially in high-voltage applications.
  • Reliable Performance Across Temperature Range: Our thermal gap pads are engineered to maintain their properties across a wide temperature range, making them suitable for extreme operating conditions and rugged environments.
  • Easy Application and Reusability: 3G Shielding's thermal gap pads are user-friendly and easy to install, saving valuable time during assembly. Additionally, they can be repositioned or reused without compromising their performance, reducing material wastage and costs.
