Graphite TIM dissipates module heat in demanding environments

A new type of graphite thermal interface material (TIM) from Panasonic Industry provides efficient thermal dissipation on power modules, says the company.

Operating power modules in demanding and even harsh industrial and automotive environments means that handling heat can be challenging.

The conventional approach is to mount modules on dedicated heat sinks and using a layer of grease for heat dissipation. The grease has to be replaced from time to time, which can be labour-intensive. Another factor is that the grease does not stay where it is applied which can counteract effective thermal dissipation, says Panasonic Industry.

The company says these issues are addressed by the latest Panasonic Industry’s GraphiteTIM. It has released its compressible EYGR TIM, reducing the thermal resistance by filling the gap and the unevenness on the surface of both power module and heatsink to enhance thermal dissipation performance.

It has a thermal resistance of 0.2 K∙cm2/W (at 600 kPa) and a thermal conductivity in X-and Y- direction from 200 to 400W/m∙K, respectively 28W/m∙K in Z-direction. The Panasonic Industry GraphiteTIM types have a wide operating temperature range of -55 to +400 degrees C for power module in many electronic devices.

Target applications are inverters, converters, automotive control units, medical equipment or server infrastructures which require reliability, longevity and ease of service.
