Indium metal has a high thermal conductivity (86W/m-k) but silver, gold, and even aluminum, have higher thermal conductivity. Read more about our use of cookies here. Calculating the thermal conductivity of an alloy is not done by taking an average (or weighted average) of its elemental constituents. Alternation of gas pocket and solid material causes that the heat must be transferred through many interfaces causing rapid decrease in heat transfer coefficient. The InN thermal conductivity, obtained from measurement of InN ceramics, was 45 W/ (m-K) This is much below 176 W/ (m-K), the ideal lattice estimate based on phonon-phonon inelastic scattering, indicating a large contribution from point defects and grain boundaries to phonon scattering. So, I went to Bob Jarrett, one of the designers of the Heat-Spring, to find out why indium works better than these other materials. The materials currently in the database are ones commonly used in the construction of cryogenic hardware. Metal thermal interface materials (TIMs) are known to have higher isotropic thermal conductivity than any non-metals.

The thermal conductivity of an alloy is impacted more by the chemical bonding structure between the inclusive elements than by the measured conductivity each element exhibits alone. Liquids tend to have better thermal conductivity than gases, and the ability to flow makes a liquid suitable for removing excess heat from mechanical components. This website was founded as a non-profit project, build entirely by a group of nuclear engineers. We look forward to learning more about your applications. Its key advantage is its high bulk thermal conductivity, but other attributes include a low tensile strength and indium's ability to lower melting temperatures So, you can use an indium thermal interface as an attach material without destroying temperature-sensitive components or disturbing other solder joints on your board. The presence of a solid solder preform absorbs and contains the liquid alloys while improving thermal conductivity. This may not seem logical, but is correct. In fact, in pure metals such as gold, silver, copper, and aluminum, the heat current associated with the flow of electrons by far exceeds a small contribution due to the flow of phonons. K minimum. The measurements have been performed at atmospheric pressure in a range of temperatures from 450 to 750 K using a new experimental method based on the principle of the transient hot wire technique. Their contribution to the thermal conductivity is referred to as theelectronic thermal conductivity, ke. To improve package reliability, it is especially important to choose the right alloy. Semiconductor superlattice structures have shown promise as thermoelectric materials for their high power factor and low thermal conductivity. The lower the thermal conductivity of the material the greater the material's ability to resist heat transfer.
