New from Panasonic and in response to the problems associated with thermal management in smaller and more complex electronic devices is PGS or Pyrolytic Highly Oriented Graphite Sheets. Made of graphite with a structure that is close to a single crystal, it combines high thermal conductivity with a thin and low weight structure. The Panasonic PGS is now available at from Rutronik.
Thermal problems increase with the miniaturization and the high density mounting of devices and effective thermal solutions are becoming more and more important in order to reach desired performance levels and to meet specific design standards. The PGS from Panasonic provides two main thermal functions: it transfers the heat energy from the heat source to the heat sink. This allows a design positioning the heat sink not directly at the heat source. And the PGS acts as a thermal interface dispatching the heat to the heat sink, thus improving the efficiency of the heat sink.
One of the effects is the reduction of hot-spots. The PGS allows heat energy to be spread out and improves the reliability of the semiconductor that produces the heat. These features make the PGS suitable as a thermal solution for LED lighting solutions, automotive lighting equipment, medical, industrial and optical equipment, telecom, communication, handheld and portable devices, semiconductor manufacturing equipment, embedded and PC applications, battery cooling, the temperature reduction of housing of devices and all miniaturized and downsized devices.
The PGS has a high thermal conductivity of 700-1750W/mK. It is very thin (17-100µm), light weight (1-2g/cm3) and highly flexible in bending and shaping.
