Trace width, current carrying capacity, and via current tools help engineers size copper and interconnects before fabrication.
Use single-ended and differential impedance tools to estimate routing constraints before final stackup review.
Use material and stackup planning tools to move from rough assumptions toward manufacturable PCB decisions.
RFQ preparation
Prepare files before quote review
Use these tools to organize manufacturing requirements, file readiness, BOM data, and engineering notes before contacting the team.
Prepare Gerber, BOM, assembly notes, testing needs, and manufacturing specs before requesting a quote.
Upload Excel or CSV BOM files to find missing fields, duplicate designators, quantity mismatches, MPN issues, and quote-readiness problems.

Power & current tools
Need more than a calculator?
These tools are best used as engineering estimates. Final routing, stackup, copper weight, controlled impedance, drilling, and manufacturability decisions should still be reviewed against real fabrication capability.
- • Use calculators early to size traces, vias, pair spacing, and stackup targets
- • Validate assumptions with fabrication stackup and manufacturing limits
- • Contact engineering when current, impedance, or reliability requirements are tight
