PCB side plating, or edge plating, involves copper along PCB edges, enhancing connectivity, conductivity, shock protection, and assembly, especially for small boards. Used in Wi-Fi and Bluetooth modules, it improves signal quality and EMC. Limitations include necessary design gaps and exclusion of V-cuts.

Plated-through slots (PTS) in PCBs are copper-plated apertures for electrical connectivity, offering space optimization, reduced soldering voids, and improved surface use.
