PCB manufacturing is the process of building physical PCB boards from PCB circuit board design according to specifications. Understanding design specifications is important because it affects the manufacturability, performance, and yield of PCB boards. One of the specifications to be followed is “balanced copper” in the manufacture of PCB boards. Consistent copper coverage must be achieved in each layer of the PCB stack to avoid electrical and mechanical issues that can hinder circuit performance. Balancing copper on a PCB is a method of symmetrizing copper traces in each layer of the PCB stack, which can avoid distortion, bending, or warping of the printed circuit board. PCB circuit board balancing copper has the following functions:
1. The use of wiring in the etched layer can reduce internal damage.
2. Use to reduce the cost of additional cooling components
3. Increasing the thickness of conductors and surface pads can strengthen interlayer copper connections.
4. PCB circuit board balancing copper reduces ground impedance and voltage drop, thereby reducing noise and improving power efficiency.
