At Robert Bosch GmbH, metamodeling was applied as an alternative to electro-thermal-mechanical FEM simulation in order to accelerate the assessment of temperature fields or contact stresses.
Electronic circuit boards are used in a wide variety of engineering applications. In the automotive industry, for instance, they can be found in electronic power steering assemblies. This case of application was also used as a test vehicle for the method that is described in this article. Other examples are battery load control circuits, motor control or safety devices like traction control and ESC. These circuit boards are constantly exposed to environmental influences like changing climate conditions (humidity), hazardous chemical conditions, vibration and mechanically and thermally induced stresses.
