1.4.1.3. Connector Breakout

For high-speed routing, use the correct breakout orientation to avoid long stubs caused by the connector pin and PCB pad.

Figure 13. Connector Pin and PCB Pad ConnectionThis is a surface-mount, ground-signal-signal-ground connector pin interconnection with the PCB. The different layers in the stackup are indicated with different colors.

Optimize and tune the connector break-in and breakout to reach the target trace impedance and increase continuity. To accurately capture the interaction between the connector pin and PCB pad, co-simulate the connector-to-PCB interaction with connector structures integrated with the PCB by a 3D EM simulation tool.
