Abstract
The present disclosure describes printed circuit board performance evaluation techniques. In some cases, a printed circuit board performance evaluation process may include determining a first set of electrical properties associated with an interface between components of a printed circuit board, where the interface is disposed on an internal or external layer of the printed circuit board. After selective application of a sheet of dielectric material to a portion of a transmission line in the interface, a second set of electrical properties associated with the interface may be determined. The first set of electrical properties may be compared to the second set of electrical properties to evaluate printed circuit board performance. In other cases, the interface may include a trace inductor, and electrical properties of the interface before and after application of a ferrous material may be compared to evaluate printed circuit board performance.
