Bare-board fabrication
PCB Manufacturing for Prototype and Production
Custom PCB fabrication with stack-up, material, copper, finish and impedance review. Compare board options and prepare files for a VeriPCB manufacturing quote.
What this service solves
A controlled path from requirements to acceptance
PCB fabrication produces the bare circuit board: the substrate, copper interconnects, holes and surface finish. VeriPCB reviews your fabrication data and order requirements before confirming the build. If you also need components mounted and tested, see custom PCB assembly.
Best fit for
- Hardware startups needing a responsive manufacturer from first article to pilot
- OEMs with high-mix or revision-controlled programs
- Industrial, IoT, energy and robotics teams needing traceable builds
- Buyers comparing manufacturers on engineering communication, not price alone
Scope

| 07 · Packaging, identification and agreed release records | Verified before release | Inspection, test or shipment evidence by scope |
Typical build sequence
- 01
Build package
Gerber or ODB++, BOM, centroid, drawings, quantity and acceptance needs.
- 02
Engineering review
Resolve revision, manufacturability, material and test ambiguities.
- 03
Fabrication & sourcing
Prepare boards and approved components against the frozen package.
- 04
Assembly
Run SMT, THT and any agreed programming or mechanical work.
- 05
Inspection & test
Apply the project-specific visual, optical, X-ray and electrical plan.
- 06
Release
Verify records, labeling, packaging and shipment configuration.
Start with your actual project
Bare PCB fabrication review
Use the enquiry form to describe the decision you need help with. We select the relevant project context; you remain in control of the details.
- Gerber or agreed fabrication data, drill files and fabrication drawing
- Stack-up, material, copper, finish and impedance requirements
- Quantity, panel format, target date and destination
This is for unpopulated boards. Assembly, components and functional testing are separate unless added to the agreed scope.
Request this reviewSpecify the board before comparing fabrication prices
| Buyer decision | Include in your request | Why it changes the quote |
|---|---|---|
| Construction | Layer count, finished thickness, outline and approved stack-up | Material set, lamination and manufacturing route |
| Copper and thermal needs | Finished copper requirements and operating constraints | Etching, plating, thermal balance and tolerances |
| Impedance | Controlled nets, target values, tolerances and coupon/report needs | Stack-up review and electrical verification scope |
| Holes and surfaces | Drill data, via treatments, finish and solder-mask requirements | Additional operations and assembly compatibility |
| Delivery | Board quantity, panel requirements, target date and destination | Panel utilization, material readiness and logistics |
Board thickness and copper alone do not define a production specification. Resolve drawing conflicts and approve the stack-up before fabrication.
Workflow
How a build moves forward
- 01
Qualification
Confirm product stage, quantities and commercial fit.
- 02
File review
Identify missing data and manufacturability conflicts.
- 03
Quotation
Separate material, fabrication, assembly, test and logistics assumptions.
- 04
Approval
Freeze revisions, alternates and acceptance criteria.
- 05
Build & validation
Manufacture against the approved package and record agreed results.
Before release
Issues to resolve with the build team
Record an owner and an agreed resolution for any issue that applies to your design.
- Conflicting fabrication and drill revisions
- Unapproved laminate or stack-up changes
- Unspecified finished copper or hole tolerances
- Missing impedance targets or acceptance limits
- Panel format incompatible with the assembly process
Buyer questions
Frequently asked questions
What is the difference between PCB fabrication and PCB assembly?
Fabrication creates the bare circuit board, including copper interconnects, holes and surface finish. Assembly mounts and solders components onto that board. Specify whether your quotation is for bare boards, assembly only or a complete PCBA build.
How is VeriPCB different from a component marketplace or broker?
We operate as one accountable build partner with engineering review. Fabrication limits, process route, sourcing controls and test coverage are confirmed against your actual design files, not assumed from a generic equipment list.
What files should I send for a PCB fabrication quotation?
Provide Gerber and drill files or an agreed manufacturing-data format, fabrication drawing, stack-up requirements, quantity, target date and destination. Include material, finished thickness, copper, surface finish, impedance and electrical-test requirements. BOM and placement files are additionally needed when requesting assembly.
Can one manufacturer handle PCB fabrication and assembly?
Yes. A turnkey model can combine bare-board fabrication, component sourcing and assembly under one coordinated plan, subject to an agreed responsibility and substitution process.
How are PCB fabrication lead times confirmed?
Timing depends on material availability, layer structure, hole and via processing, surface finish, panel quantity and required verification. Confirm the production start conditions, fabrication schedule and shipping time separately.
Will you protect my design and intellectual property?
Customer design files remain the customer’s property. An NDA can be requested before confidential files are exchanged, and we do not reuse or disclose customer designs.
What certifications should I verify before supplier approval?
Request the current certificate pack, certificate number, issuing body, expiry date and covered site directly from sales. This page does not present planned certifications as completed; certification scope must be verified per project.
