HDI PCB Design Guidelines
Ensuring Proper Stitching Vias or Ground Vias:
- Determine via spacing and distribution based on signal frequency requirements and desired isolation levels
- Place vias regularly along signal traces for effective coupling with ground planes
- Connect vias to solid ground planes without interruptions for optimal return paths
- Select appropriate via diameter and aspect ratio for conductivity and thermal dissipation
- Minimize via stub lengths to reduce impedance discontinuities and signal reflections
- Consider ground via arrays for enhanced isolation and reduced return path inductance
- Perform signal integrity analysis through simulation to validate via effectiveness
Determining Transmission Line Characteristic Impedance:
- Use empirical formulas for approximate calculations in standard configurations
- Employ field solver simulations (Ansys HFSS, CST Studio Suite) for precise results in complex designs
- Consider layer stackup, trace geometry, and dielectric properties in calculations
