While the components of a PCB (printed circuit board) are often seen as the most important part of a PCB unit, many engineers will not pay close enough attention to the layout of their PCBs. Without a proper layout, your PCB might not be reliable enough.
The Limitations of Copper
PCBs rely on copper to transfer power from one area of the PCB to another. However, copper has some resistance and you may experience a voltage drop and a rising temperature because of the resistance.
