Abstract: A pin map covers a surface area of a layer of a printed circuit board (PCB). The pin map includes a plurality of electrical designations for each pin in the pin map and a plurality of empty spaces within the pin map. Each electrical designation may be assigned to a pin on the pin map. Each electrical designation includes a positive polarity (P+) pin, a negative polarity (P−) pin, or an electrical ground (G) pin. If a space in the pin map does not have an electrical designation, then it may include an empty space/plain portion of the printed circuit board (PCB). The pin map may include a plurality of rows and a first repeating pin polarity pattern. The first repeating pin polarity pattern may include a lane unit tile. The pin map may help couple two circuit elements together that are attached to one layer of a PCB.
