Determine the required number of layers for the PCB based on the complexity of the design, signal integrity requirements, and space constraints.

2.Signal Integrity:

Place high-speed signal traces and critical signal paths on inner layers to minimize signal degradation and interference. Consider controlled impedance routing for high-frequency signals.

3.Power and Ground Planes:

Incorporate power and ground planes in the stack-up for efficient distribution of power and to reduce noise and electromagnetic interference (EMI).

4.Signal Layer Arrangement:

Determine the arrangement of signal layers and adjacent planes to minimize crosstalk and ensure good signal integrity. Alternating signal and ground plane layers is a common practice.

5.Thickness and Copper Weight:

Determine the appropriate thickness of the ITEQ IT-968 material based on the mechanical requirements and impedance control. Consider the required copper weight for power and ground planes.
