When designing a PCB, one of the most basic issues to consider is how many wiring planes, ground planes, and power planes are needed to achieve the functions required by the circuit, and the number of planes of the printed circuit board wiring planes, ground planes and power planes is determined. All these are related to circuit function, signal integrity, EMI, EMC, manufacturing cost, etc. requirements.For most designs, there are many conflicting requirements for PCB performance requirements, target cost, manufacturing technology, and system complexity. The PCB stack-up design is usually a compromise decision after considering various factors. High-speed digital circuits and whisker circuits are often designed with multilayer boards.Here are 8 rules you should notice when designing PCB stack up.1. PCB signal, power, and ground planeThere is a signal plane, power plane, and ground plane in multiple-layers PCBs. The power plane and ground plane usually have no split solid plane, and the...
