Choose by project stage
Prototype orders support design evaluation and revision. Low-volume builds support pilot quantities and follow-on work. Production orders use an approved revision and clearly defined acceptance requirements.
Define the manufacturing scope
Provide layer construction, materials, copper, dimensions, finish, quantity and inspection requirements. Identify fixed requirements and any alternatives that can be considered during engineering review.
Separate fabrication from delivery
State whether your target is a factory ship date or an arrival date. Engineering confirmation, fabrication, dispatch and transit are distinct stages and should be agreed together.
Choose a route by project stage
Start with the purpose of the order. A prototype may evaluate a new circuit; a pilot build may establish a stable revision; production requires repeatable specifications and acceptance. Quick-turn is a scheduling requirement that can apply to a suitable build, rather than a separate board technology.
| Route | Typical decision to resolve |
|---|---|
| Prototype | What must this revision demonstrate, and what evidence is needed? |
| Quick-turn | Are the files ready, and is the target a ship or arrival date? |
| Low volume | Which requirements must be stabilized before a larger order? |
| Production | How will revisions, substitutions and acceptance be controlled? |
Bare PCB fabrication and assembly inputs
PCB fabrication produces the unpopulated circuit board. PCBA adds component assembly to the agreed scope. Fabrication artwork and drill data define the board; assembly requires additional component and placement information. A BOM does not replace the fabrication package.
