Do you know Thermal Conductivity sheet for CPU?

Thank you for reading my blog all the time.

Since I opened this blog, many people emailed me and asked, "don't you have more applications which you can share with us?"

So I would like to measure Thermal Conductivity Sheet for cooling CPU.

The sheet is made of mixing fillers like Alumina in Silicon rubber.

Not only raise the thermal conductivity, but it also gives the flexibility and adherence.

This enables to reduce the thermal resistance between CPU and heat sink or other surface touching CPU.

Our Thermowave Analyzer is useful for the Thermal Conductivity sheet for CPU.

I would like to share the measurement result later.

So please keep in touch with us.

How to measure the coating of carbide tool?

The carbide tool is made of mixing Cobalt with Tungsten Carbide(WC).

To improve the quality, it will be coated with either Titanium Nitride(TiN), Titanium Carbon(TiC), Aluminum Nitride(AlN), or Diamond Like Carbon(DLC).

Normally, measuring the thermal property of these coatings were very difficult.

However, they could be evaluated with our Thermal Microscope(TM3).

The above picture is an example of evaluating the coating of a Carbide tool.

We scan the coating region and substrate region in a line.

The features of TM3 are:

1. TM3 could evaluate with a spatial resolution of 3um.

2. The thermal conductivity of coating on a substrate could be evaluated.

3. TM3 could evaluate the sample from out-of-plane orientation as well.

4. Tm3 could evaluate the thermal conductivity of thin films(100nm - ).

As conclusion, TM3 could

1. Measure the thermal conductivity of coatings.

2. Evaluate the intermediate region between coating and substrate.

If you have any questions, feel free to contact us.
