Abstract
The invention relates to a printed circuit arrangement comprising a printed circuit board having a corrosion test circuit comprising at least two conductive pads which are located proximate to each other in a measuring area, the arrangement further comprising a measuring device, characterized in that one pad is an excitation pad, being connected to an excitation signal source, and the other pad is a response pad, whereby the measuring device is connected at least to the response pad. This arrangement allows the measurement of the corrosion of a printed circuit board including short circuits and line cuts.
