The invention relates to a method for producing a control circuit (1) for a steering system (8) of a motor vehicle, comprising a semi-flexible printed circuit board (2) having an insulating carrier material on which conductor tracks (22) made of an electrically conductive material are arranged, said conductor tracks being connected to electrical components (3), wherein the printed circuit board (2) has at least two substantially rigid printed circuit board sections (23) which are connected to each other by means of a bendable connection section (24). In order to be able to improve production with less cost and higher safety, the invention proposes that a thermal modification (25) is produced in the connecting section (24) by heating the carrier material at least in sections to the molding temperature in order to reduce the bending stiffness.

    本发明涉及一种用于机动车转向系统(8)的控制电路(1)的生产方法,所述控制电路包括半柔性印刷电路板(2),其具有绝缘载体材料,载体材料上布置有由导电材料制成的导体轨道(22),这些导体轨道与电气元件(3)相连,其中该印刷电路板(2)具有至少两个基本刚性的印刷电路板区段(23),其通过可弯折的连接区段(24)互相连接。为了能够以更少的成本和更高的安全性改进制造,本发明提出,在连接区段(24)中,通过将载体材料至少区段性加热到成型温度而产生热改性部(25),以降低弯曲刚度。
