Patent ID: 7313001

Claim:
An electrical circuit arrangement comprising electrical and/or electronic components ( 4 ), conductor tracks ( 6 ) for electrical connection of the components ( 4 ), and a mount substrate ( 5 ), wherein the components ( 4 ) and the conductor tracks ( 6 ) are arranged on the mount substrate ( 5 ), wherein the mount substrate ( 5 ) comprises a metal part ( 7 ), which has an electrically insulating coating ( 9 ) on one surface of the metal part ( 7 ) which faces the components ( 4 ) and the conductor tracks ( 6 ), and wherein at least one component ( 4 ) and/or at least one conductor track ( 6 ) are/is located on the coating ( 9 ) and wherein the metal part ( 7 ) comprises a highly thermally conductive metal selected from aluminum, aluminum alloy, steel or metal alloy and wherein the electrically insulating coating ( 9 ) has a dielectric strength of at least 400 V for DC applications, and has a dielectric strength of at least 2000 V for AC applications and wherein at least one component is a power semiconductor ( 11 , 12 ), the coating ( 9 ) has a cutout ( 13 ), such that the power semiconductor ( 11 , 12 ) is mounted directly on the metal part ( 7 ), or the power semiconductor ( 11 , 12 ) is mounted on the coating ( 9 ), and the power semiconductor ( 11 , 12 ) is in the form of a chip without a housing and has a bonded connection for the conductor track ( 6 ) on the coating.
