A fabrication package should identify controlled dimensions and the evidence needed at acceptance. Material substitutions and stackup adjustments require documented engineering agreement.

Specify the bare board beyond its layer count

Use the requirements below to prepare a focused project review. Confirm the work scope, acceptance criteria and responsibility for engineering changes in writing before production is released.

Information to include in your RFQ

  • Stackup, thickness and copper weights
  • Drill chart and hole tolerances
  • Finish, impedance and electrical test requirements

Compare proposals on the same scope

Separate recurring unit cost from tooling, setup and test-development charges. Check what is included in inspection, traceability, packaging and disposition of nonconforming units. Ask which assumptions could change the quoted price or schedule.

Capability confirmation

[NEEDS CLIENT INPUT]: approved process capabilities, equipment, certificates, MOQ and available production lead times for this service.

These requirements describe a purchasing and engineering review, not a verified statement of factory capability.
