Indium Tin Oxide is an alternative material that is both transparent and electrically-conductive. Using one of these alloys alone would provide superior thermal conductivity, but would also require containment of the liquid. 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. measures of association in statistics pdf. Indium Corporation does not recommend, manufacture, market, or endorse any of our products for human consumption or to treat or diagnose any disease. All of our thermal interface materials are metal-based, which means they have a very high conductivity as compared to polymer-based thermal interface materials. 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. These alloys can be pure indium, indium alloys, Pb-free, or Pb-contained. Thermal Conductivity of Materials. All of our thermal interface materials are metal-based, which means they have a very high conductivity as compared to polymer-based thermal interface materials. For vapors, it also depends upon pressure. The cross-plane thermal conductivity of InGaZnO (IGZO) thin films was measured using the 3 technique from 18 to 300 K. The studied morphologies include amorphous (a-IGZO), semicrystalline (semi-c-IGZO), and c-axis-aligned single-crystal-like IGZO (c-IGZO) grown by pulsed laser deposition (PLD) as well as a-IGZO deposited by sputtering and by solution combustion processing. Indium Corporation 1996-2022. al. Do you have other "burning" questions on thermal management? Measuring thermal conductivity is straightforward, and can be solved for using the equation = PL/(AT) (1) Where T is the temperature gradient (T1 - T2), L is the distance between T1 and T2, A is the area of a fiber, P is the power being supplied to the sample, and is the thermal conductivity. Phonons play a major role in many of the physical properties of condensed matter, like thermal conductivity and electrical conductivity. As was written, in liquids, the thermal conduction is caused by atomic or molecular diffusion, but physical mechanisms for explaining the thermal conductivity of liquids are not well understood.

The indium bonded sample was The measured thermal conductivity in the in-plane direction, in 8.5 2 W/m K, is an order of magnitude higher than that in the through-plane direction, through 0.760.15 W/m K, which implies a high thermal anisotropy 11 3. In fact, lattice thermal conduction is the dominant thermal conduction mechanism in nonmetals, if not the only one. 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. All Rights Reserved. The mean free path also depends on the diameter of the molecule, with larger molecules more likely to experience collisions than small molecules, which is the average distance traveled by an energy carrier (a molecule) before experiencing a collision. The other three melt at close to, or over, 1,000C. To improve package reliability, it is especially important to choose the right alloy. It is recommended that, as the alloy is removed from the bottle, the volume be replaced with dry argon. Indium Corporation 1996-2022. "So You Want to be in Manufacturing?"

Denotes Materials that Indium Corporation can provide, Associate Director ESM Product Management. Because SMA-TIM products are made of metal, they cannot experience pump out problems - even under power cycling. In contrast, for alloys, the contribution of kph to k is no longer negligible. He told me there are two key characteristics that give indium the advantage over these other metals: Temperature and Flow Stress. Both of these values are very high. Alloy: 97In 3Ag Diameter: .030" Quantity: 3 FT Spool Liquidus Melting Temperature: 143C Eutectic Solidus Melting Temperature: 143C Eutectic Pb-Free: Yes This low melting point also means that indium is annealed at room temperature - it returns to the softened state without heat," according to Bob.
