Electronic circuit for use in automotive area, has heat producing component exhibiting housing side that is connected with printed circuit board by attachment element, which separates housing side regarding heat transfer from circuit board

摘要

The circuit (10) has a heat producing component e.g. chip (30), an injection molding mass (40) and a heat conducting body (50), exhibiting electrical connections (150), which provide an electrical connection between the component and a printed circuit board (PCB) (20). The component has a heat emission surface (60) extending on a side that is provided opposite to a component housing side (70), which is connected with the PCB by attachment elements (110-140). The elements are heat insulated, and separate the housing side regarding heat transfer from the PCB and formed from plastic or ceramics. The component is provided as a transistor, MOSFET, a bipolar transistor, a junction FET, a high speed diode such as schottky diode, a TRIAC or other power semiconductor, processor and other integrated circuit. The attachment elements are formed as a fastening part, plastic bar or pin and glue layers. An independent claim is also included for a method for producing a circuit.
