PCB Stack-up

This following provides examples for great Printed Circuit Board (PCB) stack up design. There are always exceptions to the following examples because each situation is different. As an engineer, your challenge is determining what design practices are necessary for a given set of conditions.

It is highly recommended to review the PCB stack-up with your PCB manufacturer before you start your board layout design.

PCB Layout Recommendations

1. Use horizontal and vertical routing of adjacent layers

2. Providing buried layers for high-speed signals (shield)

3. Separate the power and ground planes

4. For a high-performance layout put each signal layer adjacent to at least one power plane
