What is PCB Stack-up

PCB Stack-up refers to the arrangement of copper layers and insulating layers that make up a PCB prior to board layout design.

While a layer stack-up allows you to get more circuitry on a single board through the various PCB board layers, the structure of PCB stack-up design confers many other advantages:

  • A PCB layer stack can help you minimize your circuit’s vulnerability to external noise as well as minimize radiation and reduce impedance and crosstalk concerns on high-speed PCB layouts.
  • A good layer PCB stack-up can also help you balance your need for low-cost, efficient manufacturing methods with concerns about signal integrity issues.
  • The right PCB layer stack can enhance the Electromagnetic Compatibility of your design as well.

The simple stack up is 2layer, please see the stack up as below:

It will very often be to your benefit to pursue a stacked PCB configuration for your printed circuit board-based applications.

For multilayer PCBs, general layers include ground plane (GND plane), power plane (PWR plane), and inner signal layers.

Why Need Stack-up

Before designing a multi-layer PCB, designers need to first determine the circuit board structure according to the size of the circuit, the circuit board size, and EMC requirements.

That is, decide whether to use a 4layer or 6layer or 8layer or more circuit board.

After determining the number of layers, determine the location of the inner layers and how to distribute different signals on these layers.

Planning a multi-layer PCB stack-up configuration is one of the most important aspects to achieve optimal product performance.

Improperly designed substrates and improperly selected materials will reduce the electrical performance of the signal transmission, thereby increasing emission and crosstalk, and making products more susceptible to external noise.

These problems may cause intermittent operation due to timing failures and interference, which greatly reduces product performance and long-term reliability.

On the contrary, a correctly constructed PCB substrate can effectively reduce electromagnetic radiation, crosstalk and improve signal integrity, thereby providing a low-inductance power distribution network.

And, from a manufacturing point of view, the manufacturability of products can also be improved.
