Si9000

Si9000 by Polar Instruments Ltd is a 2D PCB transmission-line field solver designed for controlled-impedance design and verification. It enables engineers and fabricators to calculate single-ended and differential impedances across common microstrip, stripline, and coplanar structures using real stackups and material parameters. With an extensive built-in structure library and intuitive what‑if tools, Si9000 helps you converge on manufacturable trace widths and spacings, evaluate the impact of dielectric thickness, copper weight, plating, and surface roughness, and document results for fabrication.

Key capabilities:

• Accurate impedance calculation for single-ended and differential PCB geometries
• Uses real stackup data and material properties to reflect manufacturable outcomes
• Rapid parameter sweeps for width, spacing, dielectric thickness, and copper settings
• Integration with Polar Speedstack for synchronized stackups and material data
• Clear reporting to communicate controlled-impedance requirements and coupon designs

Typical applications:

• Setting design rules to meet target impedances
• Validating stackup changes with fabrication partners
• Assessing material choices and copper characteristics for signal integrity in rigid, flex, and rigid-flex boards
