Terms of Use

By using StackupLab you agree to the following terms.

Provided As-Is

StackupLab is provided “as-is” without warranty of any kind, express or implied. Axel Hardware Design makes no guarantees regarding uptime, accuracy, or fitness for a particular purpose.

Calculation Accuracy

Impedance and stackup calculations are based on IPC-2141 approximations. These are useful for initial design estimation but must be verified with a 2D field solver before committing to fabrication. Axel Hardware Design is not liable for fabrication errors resulting from reliance on StackupLab output without independent verification.

Limitation of Liability

In no event shall Axel Hardware Design be liable for any direct, indirect, incidental, or consequential damages arising from the use of StackupLab, including but not limited to PCB fabrication defects, manufacturing delays, or financial loss.
