A geometric design brief for fabrication review
Results will appear here.
Model limits. Illustrative construction, not a qualified lamination recipe. Thickness excludes mask and finish. Bonding and FR-4 layers require exact material names and supplier approval. Unused inputs do not affect a 2-layer stackup. 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.
