Our calculators are based on industry standards (IPC-2221, IPC-2152, IPC-2141) and use established formulas. However, real-world PCB performance depends on many factors not accounted for in these calculations.

While we strive for accuracy, you acknowledge that:

Calculations are theoretical and based on idealized conditions
Real-world factors (manufacturing tolerances, environmental conditions, board stackup) affect results
Results should be verified with your PCB fabricator
Critical designs should be validated through simulation and/or prototyping
You are responsible for applying appropriate safety margins
