Method and limitations
The builder formats your chosen construction and procurement requirements as a text brief. Layer count and quantity must be positive integers. It does not calculate price, confirm inventory or submit an order. Downloads are created locally in the browser. The quotation link opens an external fabrication website; your requirements are not transferred automatically.
Using the result
Prepare the exact material and construction, layer count, board dimensions, copper, controlled impedances, finish and test requirements. Missing values remain visible for review. Copy or download your brief, then use the quotation link to continue on the fabrication website.
From a calculation to a released design
Keep the input assumptions with the result. Recalculate when the ordered material, dielectric height, copper or operating conditions change. Confirm the final construction with the fabricator and use field simulation or measurement wherever the simplified model omits an important effect.
