fixture-free test
XFPCB reviews fixture-free test against your submitted files, quantity and application requirements before confirming the build plan.
Testing and inspection
Flying Probe Testing for PCB Prototypes and Low-Volume Builds
XFPCB uses flying probe testing where fixture-free electrical test is useful for prototype, low-volume or complex PCB verification.
Technical Requirements for Flying Probe Testing
XFPCB offers Flying Probe Testing support for PCB and PCBA projects that require verified electrical, visual or assembly quality. We can include electrical test, visual inspection, AOI, flying probe, X-ray or customer-defined test requirements during the RFQ stage.
Inspection planning works best when critical nets, hidden solder joints, high-current areas, BGA/QFN components and functional test points are identified early. XFPCB will match the inspection method to the board and assembly requirements.
Send us the files, quantity, material preferences and inspection requirements that matter to your project. XFPCB will confirm what can be manufactured, what affects cost and what needs approval before production.
Engineering Checks
prototype testing
Clear prototype testing requirements help our team quote accurately, prepare production data and reduce avoidable clarification rounds.
opens and shorts
Our engineers confirm details for opens and shorts early, so your team can approve the order with clear next steps.
netlist and Gerber review
Production notes for netlist and Gerber review stay connected with the project to support repeat orders and future design revisions.
Production Workflow
- Confirm the electrical and assembly checks required by the project.
- Choose electrical, optical, X-ray or functional checks as appropriate.
- Run inspection and record findings.
- Use the result to support future production files.
XFPCB helps choose practical inspection steps for the board type, assembly complexity and customer acceptance requirements before production is released.
Specification Table
| Project Area | XFPCB Guidance |
|---|---|
| Best use | Prototype and low-volume orders |
| Benefit | No dedicated fixture lead time |
| Limitation | Functional behavior still needs customer-defined test if required |

Flying Probe Testing FAQs
What files help XFPCB plan Flying Probe Testing?
Send Gerber files, NC drill files, board outline, stackup notes, material, copper weight, surface finish, quantity and target lead time. For PCBA or assembly-related work, also send the BOM with manufacturer part numbers, pick-and-place data, assembly drawing, DNP notes and test expectations.
Can XFPCB review the files before production?
Yes. XFPCB can review manufacturability and quotation details before production starts. We check material choices, via structures, component package data, tolerance requirements and inspection requirements before release.
Can XFPCB support both prototype and production orders?
In most cases XFPCB can support both stages. Prototype builds help validate the design, while production planning controls repeatability, documentation, component supply and cost for future orders.
How can I reduce quotation delays?
Provide complete files, expected annual or batch quantity, destination country, special standards, inspection needs and the target schedule. If the design is still changing, tell us which details are fixed and which are under review.
Request Testing Support for Flying Probe Testing
Send your project information to XFPCB and our team will review the key manufacturing or assembly details. A complete RFQ helps us respond with a more accurate quote and a clearer production plan.
- For bare PCB projects, include Gerber, drill, stackup, material, copper, finish, quantity and lead time.
- For PCBA projects, include BOM, pick-and-place file, assembly drawing, test notes and approved alternatives.
- For application-specific projects, share operating environment, reliability expectations and packaging needs.
