ENGINEERING ANSWER
A design is ready for fabrication when its electrical intent can be translated into a clear, manufacturable construction. The package must describe materials, geometry, tolerances and acceptance evidence, not merely attach Gerber files.
What to decide before release
Review the RF stackup with the fabricator before freezing trace widths. Check reference continuity, mask, finish, connectors and panel coupons. Keep the final stackup and artwork revision together to avoid a silent mismatch.
Checks to put in your design brief
- Approve the stackup and impedance table
- Check all RF transitions
- Define test and material evidence
Important distinction
A design-rule check validates the rules entered into CAD; it does not prove that those rules match the supplier’s process.
Sources & basis
Material facts follow the cited source. Design checks are preliminary guidance, not supplier process instructions.
