A programmable reference plane (PRP) permits any input/output (I/O) pin on a substrate/module to be individually connected to the reference plane for testing purposes. The PRP works in the following manner. The PRP consists of a thin copper plate 1 (Fig. 1) containing multiple drilled holes 2 into which removable pin sockets 3 (Fig. 2) are inserted. All the drilled holes 2 in the copper plate 1 are filled with pin sockets 3 so that all the substrate/module I/O pins will be electrically shorted to the reference plane. The shorting action takes place due to the construction of the pin socket 3. As shown in Fig.
