First-pass design aids
ECAD Workbench calculators and guides are first-pass design aids. They simplify real components, manufacturing processes, environments, and failure modes, and may not represent a complete design analysis.
A numerically valid result does not establish that a component, circuit, PCB, assembly, or product is safe, compliant, reliable, manufacturable, or suitable for a particular purpose.
User verification
Users should verify equations, units, input data, tolerances, corner cases, operating conditions, transient behaviour, thermal limits, component ratings, and manufacturer recommendations.
Important decisions should be checked with current datasheets, applicable standards, independent calculations, simulation, prototype measurement, manufacturing review, and qualified professional judgement.
Safety-critical and regulated work
The service is not a substitute for a qualified engineer, safety analysis, compliance assessment, design review, or certification process. Do not rely on it as the sole basis for medical, automotive, aerospace, mains-voltage, hazardous-energy, life-safety, or other safety-critical work.
Where law, contract, or professional practice requires approval by a licensed or otherwise qualified person, users must obtain that approval independently.
Standards and third-party information
References to IPC or other standards, formulas, rules of thumb, component series, and manufacturer information do not represent certification, endorsement, or a guarantee of compliance.
Users must obtain and apply the correct current edition, scope, exceptions, local requirements, and authoritative source material for their work.
Errors and changes
Calculator logic, content, and defaults may contain errors or change over time. Users should report suspected defects and retain enough source information to reproduce important calculations.
Warranty exclusions and liability limits are handled separately in the Terms of Use and may be updated as the service matures.
