6 Layer PCB - Stackup & Prototype

What is a 6 Layer PCB

A 6 layer PCB board is in general a 4 layer PCB board with 2 extra signal layers added between the planes. The 6-layer PCB classic stackup includes 4 routing layers (2 outer layers + 2 internal layers) and 2 internal planes (one for ground and the other for power). This enhances the EMI dramatically by offering 2 buried layers for high-speed signals and 2 surface layers for routing low speed signals. The signal layers should be closed to the adjacent planes.

Standard 6 Layer PCB Stackup

The design above is the standard 6 Layer PCB stackup. But it is not suitable for every design. For example, high speed designs will typically always keep power and ground planes on adjacent layers for decoupling and designs that require low electromagnetic emissions may need to utilize additional ground planes for shielding. One final practicality to consider, always route traces perpendicular on adjacent routing layers. This can help to increase routing efficiency and minimizes crosstalk.
