To order a PCB online, export and independently review the fabrication files, define the physical and material specifications, upload the package, resolve the manufacturer’s DFM questions, and approve the final build record before payment or production release. The price shown by an instant calculator is only reliable when its options match your design.
This guide focuses on bare printed circuit boards. If you also need components fitted, the order requires a BOM, CPL, assembly drawings and test requirements in addition to the PCB fabrication data. QFPCB can review the package and provide a manual engineering quotation when the design includes controlled impedance, unusual materials, special processes or assembly.
What Do You Need Before Ordering a PCB Online?
You need a released design, manufacturing output package and written specification baseline. Do not use the shopping-cart settings as the only record of what the board should be.
- Gerber or ODB++ fabrication data with all required copper, mask, legend and profile information
- NC/Excellon drill files, including plated and non-plated information where applicable
- Fabrication drawing or readme with layer order, finished dimensions and special requirements
- Quantity, delivery destination and target schedule
- Approved board revision and a technical contact for DFM questions
How Do You Order a PCB Online Step by Step?
The safest workflow separates design approval, quotation and production release. That gives you a chance to catch a wrong upload or mismatched option before material is processed.
Step 1: Freeze the design revision
Complete schematic/layout review and DRC, update copper pours, confirm footprints and mark the released revision. Archive the native design separately from the manufacturing ZIP.
Step 2: Generate fabrication outputs
Export copper, solder mask, silkscreen, board profile and drill data using one coordinate origin and one approved output job. Include the fabrication drawing when stackup, controlled impedance, tolerances or special processes cannot be represented safely by a quote-form checkbox.
Step 3: Inspect the files in an independent viewer
Open the generated files—not the live CAD view. Review every layer alone and in combination. Check outline, cutouts, mirrored bottom layers, polarity, mask openings, legend-to-pad collisions, drill alignment and the presence of copper where expected.
Step 4: Enter board specifications
Select dimensions, quantity, layer count, material family, finished thickness, copper weight, surface finish, solder mask, legend and any special features. Match the released specification; do not choose the cheapest default when it conflicts with the design.
Step 5: Upload and compare the parsed preview
Confirm the portal detects the same size, layer count and profile you reviewed. A successful upload proves file readability, not electrical correctness. Stop if the preview omits traces, drills, cutouts or a layer.
Step 6: Review price, scope and schedule
Separate unit price from tooling, engineering, testing, panelization, special-process and shipping charges. Confirm whether quoted days begin after payment, after DFM closure or after material availability.
Step 7: Resolve DFM and engineering questions
Answer questions in writing and update the controlled file package if geometry changes. Avoid approving ambiguous “factory adjustment” language without recording the affected feature and acceptance.
Step 8: Approve a prototype and retain the record
For a new design, order a build quantity that supports assembly and testing before scaling. Save the uploaded ZIP, selected options, supplier questions, approved changes, order number and received-board inspection results.
Which PCB Specifications Must Match the Design?
Every quote option changes either manufacturability, electrical/mechanical performance, assembly compatibility or cost. Use the design requirement as the source of truth.
| Specification | What it affects | What to verify |
| Layer count and stackup | Reference planes, impedance, routing and thickness | Correct layer order and dielectric/copper assumptions |
| Finished thickness | Connector fit, stiffness and enclosure clearance | Finished value and tolerance on drawing |
| Copper weight | Trace geometry, current capacity and etching | Inner/outer copper definitions and finished expectations |
| Material/Tg family | Thermal and electrical behavior | Exact or approved equivalent requirement |
| Surface finish | Solderability, planarity, contacts and storage | Assembly process and contact-area need |
| Minimum drill and routing | Tool availability, aspect ratio and profile accuracy | Smallest actual feature against current capability |
| Controlled impedance | High-speed/RF signal behavior | Target, tolerance, layer, geometry and coupon/report scope |
How Should You Check the Gerber and Drill Package?
Check the manufacturing package as a standalone product. A correct PCB editor screen does not prove the exported data is complete.
- Layer names clearly map to top, bottom and internal copper order.
- Board outline is closed, unambiguous and includes required internal cutouts.
- Plated and non-plated holes are identified consistently.
- Drill coordinates align with pads and mechanical features.
- Solder-mask openings expose intended pads without unintended gaps.
- Silkscreen does not obscure pads or critical markings.
- Copper pours are refreshed and no expected plane or trace is missing.
- Fabrication notes do not contradict the order-form selections.
If your package is incomplete, use a formal PCB design review before release rather than relying on the fabricator to infer design intent.
When Is an Instant Quote Not Enough?
An instant quote is useful for standard constructions, but a manual engineering review is safer when the board uses blind/buried vias, via filling, edge plating, castellations, controlled-depth routing, heavy copper, unusual laminates, tight impedance, sequential lamination, rigid-flex construction or special acceptance records.
Ask QFPCB’s PCB manufacturing team to confirm the manufacturable stackup and special-process scope before treating the calculator price as final.
How Do You Compare PCB Quotes Correctly?
Normalize quotes to the same technical and commercial scope. A lower price may exclude electrical test, impedance coupons, tooling, engineering review, shipping, duties, special packaging or scrap/replacement terms.
| Quote check | Question to ask |
| Technical baseline | Which file revision and specification set were quoted? |
| Material/stackup | Is the quoted construction exact, equivalent or still pending approval? |
| Testing | What electrical-test and special-report scope is included? |
| Schedule | What event starts the lead-time clock and what approvals can pause it? |
| Freight | Which shipping method, packaging and trade terms apply? |
| Nonconformance | How are shortages, rejects and remakes handled? |
What DFM Questions Should You Expect?
Expect questions where the design conflicts with capability or leaves intent unclear: narrow trace/space, small annular rings, copper near the profile, ambiguous slots, mask dams, legend on pads, conflicting dimensions, incomplete impedance information or an unbuildable stackup. A good DFM question identifies the location, conflict and proposed disposition.
Should You Order Bare PCBs or Assembled PCBAs?
Order bare PCBs when you will source parts, assemble and test elsewhere. Order PCBA when the supplier must procure components and populate the boards. PCBA adds BOM, CPL, assembly drawings, approved substitutions, programming and test requirements. For early builds, a prototype PCB assembly quote can expose footprint, polarity and test-access problems before volume.
What Common Online PCB Ordering Mistakes Cause Respins?
- Uploading an older ZIP after the design revision changed
- Trusting the portal preview without checking each source layer
- Selecting a default layer count, thickness or copper that contradicts the layout
- Leaving impedance targets without a stackup or geometry agreement
- Using a drawing and order form with conflicting dimensions or finishes
- Scaling directly to volume before assembling and testing a prototype
- Approving a DFM change without updating the controlled record
How Should You Inspect the Boards After Delivery?
Confirm quantity, packaging, part number/revision and visible condition first. Measure critical dimensions and thickness according to the agreed sampling plan, inspect holes/profile/surface finish, and compare fabrication evidence to the purchase requirement. Assemble and electrically test prototypes before authorizing the next quantity.

Frequently Asked Questions
Can I order a PCB with only a schematic?
Not as a normal fabrication order. A schematic describes connectivity, while the fabricator needs PCB layout/manufacturing data. Use PCB design support to create and review the layout first.
Do I need Gerber files to order a PCB?
Most online systems accept Gerber plus drill data; some also accept ODB++ or native formats. Confirm the supplier’s supported inputs and review the interpreted output.
What is the difference between PCB and PCBA ordering?
A PCB order produces bare boards. A PCBA order also includes component sourcing and assembly, so BOM, CPL, assembly and test data are required.
Why does the quoted board size look wrong?
The portal may be reading an incorrect, open or duplicated outline. Stop and inspect the profile layer, units and origin rather than manually overriding an unexplained mismatch.
Should I pay before DFM review?
Workflows vary. The important control is knowing whether price and schedule can change after engineering review and having a clear approval step before production.
How many PCBs should I order first?
Use enough boards to assemble, test and learn without committing the full forecast. The right quantity depends on setup cost, failure risk and the number of validation units required.
What causes an online PCB quote to change?
Common causes include a parsed specification mismatch, special process found in the data, nonstandard material, stackup/impedance requirements, tooling, engineering questions or shipping scope.
Can the manufacturer fix my Gerber files?
Manufacturers can propose CAM or DFM changes, but functional design intent belongs to the customer. Require written approval and retain the final production data.
