Stack-up and Structure
The key to a 4-layer PCBA's performance is its stack-up, which is the arrangement of the layers. The most common and effective stack-up is:
Top Layer (Signal): The outermost layer where most components are placed and signal traces are routed.
Inner Layer 1 (Ground Plane): A solid copper layer dedicated to providing a stable ground reference for the entire circuit. This is crucial for signal integrity and EMI shielding.
Inner Layer 2 (Power Plane): A solid copper layer used to distribute power to the components, ensuring a stable and low-impedance power supply.
Bottom Layer (Signal): The other outermost layer, used for additional signal routing and component placement.
This configuration effectively sandwiches the signal layers between the ground and power planes, creating an environment that minimizes noise and crosstalk.
