In printed circuit board (PCB) design, copper pads are points for attaching components with soldering. These pads come in two primary types: through-hole and surface-mount (SMD). Through-hole pads are designed for components with leads that are inserted through the pad’s holes and soldered on the opposite side of the board. This method ensures a mechanical and electrical bond between...
