Which files should be sent for a prototype quotation?

Gerber or ODB++ data, the drill file, the BOM with manufacturer part numbers, the assembly drawing and any test requirements. If impedance or a specific stackup matters, say so in the first message rather than after the boards are made.

Why ask for a DFM review on a prototype?

Because the same review that catches a 0.05 mm trace error also catches a missing solder-mask opening or a component that cannot be placed. It costs nothing before tooling and a week after.

Outsourcing a Prototype PCB Build

A prototype is a learning cycle. The goal of the first order is a fast answer, not the lowest price per board.

Guidelines for Quick turn Prototype Circuit Board Outsourcing

Send a complete package

Gerbers, drill, stackup, BOM, assembly drawing and test plan. Missing one of these usually costs a day in questions.

Fix the decisions early

Layer count, material, finish, assembly side and test coverage are cheap to decide now and expensive to change later.

Plan the iteration

Order a small quantity, keep the tooling, and expect a revision. A prototype that is built to learn something is doing its job even if it exposes a design change. Where the prototype also has to be populated, express prototype pcb assembly and the bare board are cheaper ordered together than in two rounds.

Technical Specifications

Prototype lead time: 1–3 days for bare boards
Engineering review: free DFM/DFA before tooling
MOQ: 1 pc — no minimum on boards, assembly or components
