Dimension conversions and nominal copper reference
Results will appear here.
Model limits. 1 inch = 25.4 mm exactly. Copper weight conversion uses about 34.8 µm per oz/ft² as a nominal reference. Starting foil and finished plated thickness are different specifications. Read the methodology.
Use the result in a real design
01 · Set the construction
Use the approved dielectric spacing and material model. Keep units explicit.
02 · Check the assumptions
Compare the model limits with the geometry and frequency of your circuit.
03 · Prepare the release
Export the brief, then obtain field-solver and fabrication review.
