Sequencing of signals through a printed circuit board is obtained without the previously required special edge connectors or additional board manufacturing techniques. A printed circuit board 1 (Fig. 1) has continuous metal fingers 2 and interrupted metal fingers 3 on its upper surface 4. The printed circuit board 1 may have similar continuous metal fingers 5 (Fig. 2) on its bottom surface 6 and interrupted metal fingers, which are similar to the interrupted fingers 3, on its bottom surface 6. Each of the interrupted fingers 3 has a forward portion 7 (see Fig. 1) and a rear portion 8 with a space 9 therebetween. When the printed circuit board 1 is inserted into an edge connector, one contact finger of the edge connector rides up a chamfered edge 10 (see Fig.
