Control unit and method for designing a circuit board of a control unit
First Claim
1. A control unit, comprising:
- a circuit board;
a high-impedance circuit component situated on the circuit board and having an impedance of 1 kΩ
or higher in relation to ground of the control unit; and
at least one conductive protection element;
that is electrically connected to ground;
that is situated, adjacent to the high-impedance circuit component on the circuit board, to, within a protective distance from the at least one conductive protection element, deflect electric field components produced outside the control unit away from the high-impedance circuit component; and
a height of which is at least equal in length to the protective distance.

Abstract
A control unit, e.g., for a motor vehicle, includes a circuit board, a high-impedance circuit component situated on the circuit board and having an impedance of 1 kΩ or higher in relation to ground of the control unit, and at least one conductive protection element electrically connected to ground and situated adjacent to the high-impedance circuit component. The protection element has a height within a protective distance from the high-impedance circuit component that is at least equal to the protective distance. A method for designing a circuit board of a control unit, and a computer program product for executing the method, include the steps of specifying a position of the high-impedance circuit component, and specifying a position of the protection element such that the protection element has a height within a protective distance from the high-impedance circuit component that is at least equal to the protective distance.
