PCB prototyping: fabrication revision and verification items for this build
PCB prototyping first verifies board outlines, holes/slots, traces, and layer stackup, before deciding on the next revision or production. All bare circuit board prototyping requires Gerber files, drill files, and fabrication notes at the same revision. This category offers four-layer functional prototype and six-layer impedance verification prototype references. For prototypes with components installed, use the prototype PCB assembly service.
Prototype delivery must resolve decisions for the next version
Specify hole diameters, outline, net continuity, or impedance geometry for this bare board verification build. Reports include board IDs, revisions, changes, and raw results. Freeze only after component changes, jumpers, and rerouting discovered during later assembly and debugging are incorporated into the approved manufacturing revision.
Bare PCB prototyping: file revisions and verification items
For bare PCB prototyping, first submit Gerber files, drills, layer order, outline, quantity, and revision. State whether this build verifies mechanical fit, fabricated patterns, or impedance structures. Define material-substitution and CAM-change approval requirements. Archive prototype electrical testing and agreed test coupon results with the boards, and freeze fabrication files before production.

Consult selected PCB configuration
How do PCB prototyping and production quotes differ?
Prototyping primarily verifies a new revision; production depends on fixed construction and quantity. Unit costs may differ after setup costs are allocated, but materials, special inspections, and shipping still require separate calculation. Bare PCB prototypes and assembled prototypes cannot use the same pricing basis.
How should I select prototype configurations for mechanical fit versus impedance verification?
Mechanical fit, electrical continuity, and impedance structures each determine this prototype build's configuration. Complete the required verification before increasing quantity so a low unit price does not obscure unresolved design changes.
PCB prototyping pricing and selection FAQ
How much does PCB prototyping cost? How do quotes for 5 boards and production compare?
A project-specific quotation requires review of the available files, quantity, materials, requested tests, delivery destination, taxes, shipping, and trade terms. Add specified materials, processes, and inspections not yet included to the total cost. Standard board references do not cover every configuration of this product. Any formula on this page organizes cost inputs; it is not a quoted rate.View cost items, calculation conditions, and sources.
How should I compare PCB prototyping manufacturers' quotes?
Align individual board or panel quantities and revisions, and check engineering fees, electrical testing, and special reports. Setup allocation differs between 5 prototypes and production. Do not increase purchasing solely to lower unit pricing while the design remains undefined.
Must a prototype include an impedance report if only the board outline is being verified?
Distinguish mechanical, continuity, and interface structure tasks for this build. Unneeded special tests can be omitted, but identify uncovered performance. A mechanical prototype does not complete interface verification.
Should 5 prototypes be accepted by panel or by conforming individual board?
Specify final accepted quantity, boards per panel, and delivery form. Agree on acceptance if defective positions are included. Review setup and fabrication fees separately; do not simply count panels.
Can the original engineering setup be reused if holes change during prototyping?
Approve the new hole/outline revision first and assess CAM, tooling, and inspection impacts. Separately confirm old drawing disposition and the new schedule. Drawing changes are not unlimited inclusions in the original quote.
What evidence is needed before low-volume production after a temporary prototype material substitution?
Retain actual materials and verification conditions, then close substitutions and changes to form an approved package. Original prototype results support only the construction actually covered; do not simply increase quantity.
Consult PCB prototyping quotation: describe the application, existing configuration, and expected quantity so we can discuss bare-board fabrication requirements, inspection, and delivery conditions.
How much does PCB prototyping cost? How do quotes for 5 boards and production compare?
Quotes should separately itemize CAM and engineering setup, material area and panelization, layer count, hole-wall copper and surface finish, electrical testing, impedance coupons, and specified reports. Separate initial order setup costs from recurring batch and per-board costs. For the same quantity, also align revisions, delivery configuration, and tax and shipping terms to determine whether price differences reflect configuration or excluded work.
Quotation terms depend on the approved files, quantity, material supply, tests and delivery requirements.
