Power electronic substrate (original) (raw)
The role of the substrate in power electronics is to provide the interconnections to form an electric circuit (like a printed circuit board), and to cool the components. Compared to materials and techniques used in lower power microelectronics, these substrates must carry higher currents and provide a higher voltage isolation (up to several thousand volts). They also must operate over a wide temperature range (up to 150 or 200 °C).

| dbo:abstract | Direct bonded copper, (DBC, auch engl. Direct copper bonded, DCB), ist in der Aufbau- und Verbindungstechnik eine Struktur, die eine enge elektrisch/thermische Verbindung elektronischer Bauteile und Chips über Kupfer ermöglicht. Dies ist besonders in der Leistungselektronik für eine bessere Wärmeableitung wichtig. Es werden sowohl Hybridschaltkreise mittels Chip- und Drahtbonden als auch Metallkern-Leiterplatten gefertigt. Auf dem DBC-Substrat werden aus bzw. auf der Kupferschicht Leiterbahn-Strukturen und Kontaktflächen hergestellt, um Bauteile aufzulöten, die so besonders gut gekühlt werden, was bei konventionellen Leiterplatten aufgrund der schlechten Wärmeleitfähigkeit des Substrates nicht erreichbar ist.
