In a method for producing an electronic subassembly, at least one electronic component is fixed in place on an insulating layer of a conductive foil in a first step, the conductive foil with the electronic component is laminated onto a circuit board substrate, and a circuit track structure is then developed by structuring the conductive foil. The expansion coefficient of the insulating layer lies between the expansion coefficient of the circuit board substrate and the expansion coefficient of the circuit track structure, and/or electronic components that require small passages for contacting with the circuit track structure are pressed deeper into the insulating layer than electronic components that require larger passages in the insulating layer.
