We are back today to finish our conversation with Miloš Lazić to find out how he became interested in liquid metals.Read More
Yesterday, in Part 2 of our interview, Miloš mentioned how using a hybrid solid/liquid TIM provides benefits over thermal grease. Today we discuss the challenges of working with liquid metal, and how to address these issues.Read More
In yesterday’s post, Miloš and I discussed what he’s been working on in the lab. Today we answer a question that impacts our TIM customers.Read More
I recently caught up with Miloš, one of our Technical Support Engineers who has taken a special interest in liquid metals. In the lab, Miloš has been experimenting with / creating some of our next-generation liquid-solid hybrid metal materials. Let’s find out what drives his pursuit of the ultimate Thermal Interface Material (TIM).Read More
- TIM1: Solder preforms are used as a solder thermal interface material between a processor die and a heat-spreader at the TIM1 level.
- TIM1.5: In mobile applications or bare die applications, such as laptops or video graphics boards, there is no heat-spreader. Instead, the die is in direct contact with the cooling solution. That is why we call this thermal interface level TIM1.5. Here we recommend our compressible thermal materials, such as Heat-Springs® or liquid metal
- TIM2: In the TIM2 level between the heat-spreader and the heat-sink we also recommend our compressible interface material - Heat-Springs® or liquid metal
Thermal Interface Materials
Although many TIM1 soldering processes use indium-containing materials to obtain the lowest thermal resistance for IC cooling, our engineers and industry partners have developed a new system that out-performs the status-quo. This patented system is called mdTIM.
Pure indium metal has a superb thermal transfer rate, but air or gas pockets (voids) can degrade the performance of the material. These voids are created by entrapped air or gasses produced by flux component evaporation that fail to escape during reflow.
MdTIM does not use flux so you don’t have issues caused by outgassing. Additionally, mdTIM provides you with a thermal conductivity of 87w/mK.
This patented system of materials and reflow technology eliminates voids before they can become a problem.
