Development of innovative packaging materials based on electrically insulating particles (IPANEMA)

The project has the objective of developing and studying new materials for electrical and electronic products by combining innovative coating technologies. By optimising heat dissipation, electromagnetic compatibility and recycling potential, the project participants are improving the environmental sustainability of the materials.

Summary

The aim of the project is to achieve sustainable improvements in the competitive position of various industrial sectors involved in the manufacture of electronic equipment. The content of the project involves the development of innovative packaging processes for electrical and electronic products by combining innovative coating technologies with new application strategies. The aim is to use new plasma coating processes to utilise the properties of metallic particles and materials for use as electrically insulating materials. This allows innovative component and system concepts and designs, which have applications in various economic areas from microelectronics through to plant engineering.

Optimising heat dissipation, electromagnetic compatibility and recycling potential improves the environmental sustainability of the materials. In addition, increasing the quality and competitiveness of the systems to be developed will contribute to improving the entire value chain.

Results:

  • The fact that excellent heat dissipating capacity could be achieved with aluminium and copper proved advantageous, along with an improved method for optimising the grain size distribution.
  • Material for processing as cast resin and thermoplastic with up to 70% by volume for uncoated aluminium (approx. 85% by mass) resulted in heat conductivity of 9 W/mK. With coated aluminium at approx. 55 % by volume (approx. 76% by mass) heat conductivity of 4.5 W/mK was achieved.
  • Limitations arose due to the fact that electrical insulation can only be achieved to a limited extent, and the particle sizes suitable for the coating.
  • Demonstrators showed economic and environmental sustainability of the materials by improving the heat dissipation.
