DFM review depends on the selected process and fabricator. Separate hard process violations from yield risks and optional cost improvements; capture approved changes in a revised release package.
Resolve fabrication and assembly constraints before release
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
- Copper, drill and stackup data
- Assembly drawing and component models
- Clearance, tolerance and inspection priorities
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.
