About

RobustPCB gives you the number, a verdict on whether it is acceptable, and the equation behind it.

What it does

• Your work on any device you sign in on.
• Shareable: the page address carries your inputs, so a link reproduces the exact calculation.
• Works offline: pages you have opened keep working without a network.
• No advertising.
• Independent answers: parts, prices and sponsors never influence a result.

Reproducible and traceable

The same inputs give the same result on any machine, and every result names the engine version that produced it. Where a method comes from a published standard, the standard is cited beside the result. The Validation page shows the evidence behind each calculator.
