Unlike anything else.
Heat management is only the beginning. Carbice has proven advantages across all of the important criteria—making it the ideal thermal management solution for any project.
The amount of heat that the TIM can move. Low thermal conductivity limits the amount and leads to performance caps or, worse, melt-downs. High thermal conductivity moves more heat, but requires low thermal resistance to move it to the heat sink. Carbice® Nanotubes are some of the most thermally conductive materials on earth and maintain their conduction, even when they bend under compression.
In most cases the heat source isn’t distributed evenly across the interface. This means even high through-plane thermal conductivity will eventually bottleneck at that chokepoint. Carbice Pad's aluminum backbone delivers optimal in-plane heat spreading, using its entire surface area to distribute the heat evenly and move it out. Our standard in-plane thermal conductivity is 200 W/mK. If customers need higher specs, we can provide a 1,300 W/mK solution today.
Carbice Pad is a high-tensile, tear-proof sheet that is easily incorporated on manufacturing lines or applied by hand. Carbice Pad is tailored to your needs, pre-cut to your specs, provided in cassettes or rolls if needed. Even if your existing assembly uses grease, we are confident Carbice Pad will deliver lower total cost of ownership in the long run.
Compression events can occur with every expansion and contraction during a thermal cycle or the product’s exposure to mechanical stresses. To maintain low thermal resistance a TIM has to be able to rebound after a compression event. While carbon nanotubes are the strongest materials in terms of tensile strength and elasticity, Carbice Nanotube arrays are soft and flexible under radial pressure. When compressed Carbice Nanotube arrays buckle and absorb kinetic energy, dampening shock and vibration. But their spring-like mechanics let them recover close to 100% once released.
The ability to overcome contact gaps between a heat source/sink and the TIM. High thermal resistance means heat cannot move to or from the TIM. A TIM delivers low thermal resistance when it is able to establish gap-free contact. Carbice Nanotubes can flex and fill every void of the interface, resulting in industry-leading low thermal resistance.
Greases pump out, dry out, crack, and cause stress concentrations. But PCMs and conventional gap pads don’t hold up over time and cycling either. This leads to dramatic performance drop-off, often within the given product’s expected lifetime. Carbice Pad doesn’t degrade. In fact, Carbice Pad maintains and can even increase performance over time and cycling.
A lot of customers tell us they started using grease TIMs, because they delivered exciting thermal conductivity and thermal resistance at time zero. But the reality is greases are incredibly difficult and expensive to add in assembly and if something goes wrong, it is messy and time-consuming to rework. Reworking Carbice Pad is clean, simple, and fast, allowing for leaner manufacturing requirements and lower total cost of ownership.
To understand the sustainability impact of a TIM, we have to examine its origin materials, manufacturing processes, reliability & lifetime, and end-of-use & recycling characteristics. Carbice Pad uses recycled carbon and aluminum as input materials, requires only low-temp/low-pressure manufacturing processes, last longer than any other TIM we’ve examined, and can easily be removed and recycled at its end of life.
