1. A method for detecting errors or malfunctions in electrical or electronic components of equally composed circuit arrangements, wherein each of the circuit arrangements is located on a circuit board and wherein a plurality of circuit boards, each with a respective equally composed circuit arrangement, are provided bordering one another on a circuit board panel, the method comprising:
populating each of the circuit boards of the circuit board panel with analog, electrical, or electronic components corresponding to the circuit arrangement;
for each of the analog, electrical, or electronic components used for the construction of the circuit arrangements, placing a corresponding test component in an edge region of the circuit board panel;
ensuring the analog, electrical, or electronic test components in the edge region of the circuit board panel come, in each case, from a same batch, or from a same components roll, as the corresponding electrical or electronic components used on the circuit boards for the circuit arrangements;
providing the analog, electrical, or electronic test components placed in the edge region of the circuit board panel with test points;
checking for a correct function value and/or a correct poling of the analog, electrical, or electronic test components provided with test points and located in the edge region of the circuit board panel.
