1. Result Accuracy
Tool results provided by 555Tools are for reference only. Although we strive to ensure calculation accuracy, electronic engineering calculations may be subject to precision limitations or computational errors. Tool results should not be the sole basis for engineering decisions and should be independently verified by professional engineers.
2. Applicable Scenarios
These tools are suitable for auxiliary circuit calculations, educational demonstrations, concept verification, and other non-critical scenarios. Before applying tool results to production-grade FPGA designs, PCB manufacturing, or firmware deployment in critical systems, a comprehensive review and verification by a licensed professional engineer is required.
3. No Warranty
These tools are provided on an "as is" and "as available" basis. We make no warranties, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement. Due to the nature of electronic engineering calculations, tool output cannot be guaranteed to be absolutely correct under all conditions. Use is at your own risk.
4. Limitation of Liability
To the maximum extent permitted by applicable law, 555Tools and its operators, contributors, and affiliates shall not be liable for any indirect, incidental, special, punitive, or consequential damages arising from the use of or inability to use the tools, including but not limited to loss of profits, data loss, or business interruption. Whether liability is based on contract, tort, or other legal theory, our total liability to you shall not exceed one hundred RMB. Tool results do not replace professional engineer judgment. This disclaimer is governed by the laws of the People's Republic of China.
5. Professional Judgment
Tool results do not replace the independent judgment and review of a licensed professional engineer. When using tool output for engineering decisions, you must fully consider the application scenario, safety standards, and industry specifications. In scenarios involving personal safety or significant property, tool results should not be used as the sole basis for decision-making.
