Abstract
A printed circuit arrangement employs a printed circuit board having a corrosion test circuit provided with at least two conductive pads which are located proximate to each other in a measuring area. The arrangement uses a measuring device to identify corrosion on other defects in the circuit board including short circuits and/or line cuts. 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.
