IMS (Insulated metal substrate) technology allows the mounting of power components directly on a highly thermally conductive printed circuit board . The result is a compact and reliable solution which, thanks also to the reduced cost compared to systems with traditional heat sinks, is finding more and more application in sectors where effective dissipation of the heat generated by electronic components is required, such as of Lighting, Automotive and Power Supply . The devices can operate at lower temperatures with a guarantee of greater reliability and lifespan , avoiding the assembly phases of mechanical heat sinks. The assembly cycle is simplified and can in some cases be reduced to just the SMT assembly operation. The availability of dielectric layers of different nature and thickness offers many design possibilities from a thermal and electrical insulation point of view. It is possible to use different materials with both aluminum and

Main Features very good electrical insulation very good slide and wear properties inherent flame retardant continuous service temperature up to 260 °C very good chemical resistance good UV and weather resistance Target industries aircraft and aerospace technology chemical technology food technology cryogenic engineering mechanical engineering semiconductor technology

Rigid RIGID VINYL CHLORIDE, PVC belongs to the thermoplastics category and has an amorphous structure, high solidity and a high modulus of elasticity. It has excellent elec- trical properties, especially in the low voltage and frequency field. It is used with temperatures between – 10°C and + 60°C. Up to temperatures of 60°C, rigid PVC is stable against the majority of diluted or concentrated acids. Rigid PVC is physiologically inert. The possibility of using products in the food sector depends exclusively on the type of stabilisation. It is a good electrical insulator and absorbs little water; it can also be welded and glued.
