Understanding Thermal Interface Materials (TIM):
Efficient cooling of high-power electronic components necessitates meticulous engineering to manage heat effectively. The primary objective is to prevent junction temperatures from exceeding recommended levels, as they directly impact component longevity. Thermal interface materials play a crucial role in bridging the gap between hot components and heat sink assemblies, enhancing heat transfer and maintaining optimal component temperatures. For instance, gap filler pads facilitate heat transfer between solid surfaces.
Gap Fillers
Thermal Interface Materials
What are Gap Fillers?
Thermal interface materials, such as thermal gap fillers, are essential for electronic components to dissipate heat efficiently due to their excellent thermal conductivity characteristics. By filling voids and displacing air, these materials optimize heat transfer within devices and systems. Given air’s poor heat conduction properties, these scientifically designed gap fillers are instrumental in maintaining components at lower temperatures, ensuring they operate within acceptable thermal limits.
- Enhance heat dissipation for electronic components through their excellent thermal conductivity.
- Fill gaps to eliminate air, a poor heat conductor, promoting efficient heat transfer.
- Bridge significant gaps between heat-producing and heat-dissipating surfaces.
- Can cover multiple heat sources within an application, accommodating varying heights.
- Compliant and pressure-sensitive, they maintain optimal thermal performance without excessive stress on the system.
- Typically silicone-based, they may also contain thermally conductive fillers like BN, ZnO, and alumina.
- Standard thickness ranges from 0.25 to 5mm, allowing deflection without exerting excessive pressure.
- Ideal properties include low thermal resistance, high thermal conductivity, and low contact resistance for better surface wetting.
- User-friendly, exhibit low outgassing/bleeding, and prevent silicone condensation in optical applications.
How do Thermal Gap Fillers Function?
Thermal gap fillers, created in laboratories, are inserted into electronic systems to fill tiny air pockets and narrow gaps between hot components and heat sink assemblies or chassis. These gaps typically impede heat transfer due to air’s poor thermal conductivity.
Utilizing their remarkable thermal conductivity, gap filler formulations address this issue by spanning the previously air-filled gap. By efficiently conducting heat away from delicate components, these materials help ensure devices remain compliant and operate within specified temperature thresholds.

Liquid Gap Fillers
Thermal Interface Materials
Liquid gap fillers, used in thermal management, are thermally conductive materials that optimize heat transfer between heat-generating electronic components like integrated circuits or transistors and heat-dissipating mechanical elements such as heatsinks.
How do Liquid Gap Fillers Work?
These liquid materials flow between the hot component and the heatsink, eliminating any air gaps or voids to ensure efficient thermal conduction.
Alternative Thermal Fillers:
Apart from liquid gap fillers, another prevalent type is thermal gap pads, which offer similar benefits. Unlike liquid fillers, gap pads are solid and manually or robotically placed on components.
Advantages of Laird’s Liquid Gap Fillers:
Laird’s liquid gap fillers excel in filling large and irregular gaps without exerting excessive pressure, facilitating superior thermal management. Their product range includes one and two-part materials, as well as options optimized for vertical stability and consistent dispensing..
Automated Application Innovation by Laird:

Phase Change
What are Phase Change Materials?
Thermal Interface Phase Change Materials are used to enhance thermal transfer between a hot component and a thermal solution like a heatsink. This enables the component to run at a lower temperature whereby increase speed and extending life. Phase Change Materials are used in the most demanding application across many industry segments. These include consumer electronics, telecom/datacom, automotive electronics, industrial electronics, medical and military/aerospace.
How do Phase Change Materials Work?
The first PCMs melted to a liquid state at temperatures between 50C-60C. This “phase change” allowed the material to wet the mating surfaces, and flow to a minimum bond line to provide the lowest possible thermal resistance, the best performance. Today most PCMs do not change state (melt) but soften at operating temperatures in the 50C to 70C range whereby providing the same advantages of wetting and minimum bond line but further provide much better long-term reliability (more resistant to pump out) than earlier materials that truly phase change to liquid. PCMs are generally used in constant pressure application (with some type of spring loaded heatsink).
Characteristics and Functions:
- Thermal conductivity range: 1 – 8 W/mK
- Thickness range: 0.125mm to 0.5mm
- Compliancy: UL 94V0, RoHs, REACH
- Easy to use; peel and stick format with top tabbed liners or automatable placement
