HDI PCB Design Guidelines
Follow these key considerations for optimal characteristic impedance in your HDI PCB design:
- PCB Material Selection: Choose materials with consistent dielectric constant for accurate impedance values
- Layer Stackup: Maintain uniform dielectric thickness and avoid abrupt changes in material
- Trace Geometry: Follow manufacturer guidelines for width, spacing, and thickness
- Differential Pairs: Maintain consistent trace dimensions for balanced impedance
- Via Design: Minimize vias in signal path and use controlled impedance vias when necessary
- Ground Plane Configuration: Ensure solid ground plane with proper stitching vias
- Manufacturing Tolerances: Account for production capabilities in your design
