Legislation in Germany and in many other countries states that electronic devices should be protected against fire. In accordance with this, most electronic and electrical products contain substances which are flame retarding, but have harmful environmental implications. Thus, the protection of the environment makes it necessary to eliminate these harmful substances. The described base material consists of silicone filled with alumina. Silicone is a non‐toxic material. The filler increases the thermal conductivity of the material. As a result of its good thermal properties, the material does not need flame retarding substances, but is still able to satisfy the fire protection requirements. The properties of the material itself and the construction allow the building of an excellent, non‐flame retarded and therefore environmentally friendly 3D‐circuit board.
