One accountable contact from review to handover

PCBLaunch engineering service

PCB Prototyping, Assembly and Testing

Review the current file package, build an initial board, define the checks, and use findings to prepare the next revision.

Best fit

Teams that already have design files and need a coordinated route through fabrication, component sourcing, assembly, power-on checks, functional testing, and revision decisions.

Useful starting material

  • Gerber and drill data
  • BOM and placement data
  • Assembly drawings
  • Quantity and revision
  • Firmware or programming information if required
  • Test steps, expected behavior, and available fixtures

Engineering approach

What happens after the first review

File review before fabrication

Gerber layers, drill data, board outline, BOM, placement data, and assembly notes are checked for alignment. Questions are raised where the package conflicts or leaves an assembly decision open.

Prototype as an engineering checkpoint

The first build is used to expose manufacturing, sourcing, assembly, and test questions while the cost of change is still manageable. It is not presented as proof of production readiness by itself.

Pre-power checks

Where the project supports it, polarity, orientation, shorts, supply rails, and programmed-device prerequisites are reviewed before power is applied. The exact checks depend on the design and available information.

Functional testing with a stated boundary

A useful functional test names the input condition, action, expected result, and recorded observation. If a fixture, golden sample, firmware, or customer procedure is missing, the resulting limitation is made visible.

Close the loop into revision control

Issues are separated into assembly defects, sourcing decisions, design changes, documentation gaps, and test limitations. That separation helps the customer decide whether to rework, build another prototype, or release a small batch.

A five-stage project path

  1. 01

    Review the package

    Align fabrication, assembly, sourcing, firmware, and test references.

  2. 02

    Confirm prototype scope

    Set quantity, assembly needs, hold points, and decision owners.

  3. 03

    Build the first boards

    Coordinate fabrication, sourcing, assembly, and programming inputs.

  4. 04

    Apply agreed checks

    Run the defined pre-power and functional checks with visible limitations.

  5. 05

    Decide the next revision

    Separate rework, documentation, design, and sourcing findings.

Expected project outcomes

01

Pre-build question list

02

Agreed prototype and assembly scope

03

Testing scope tied to available procedures

04

Recorded observations and issues

05

Clearer decision on release, rework, or revision

Boundaries that stay visible

No generic production promise

Board construction, quantity, pricing, timing, component availability, test coverage, and handover records are confirmed from the submitted project. Partner facilities are coordinated when required and are not presented as PCBLaunch-owned factories.

Frequently asked questions

Can you build from Gerber files only?

Fabrication may begin from a valid Gerber and drill package, but assembly also needs a usable BOM, placement data, and assembly information.

Do you write firmware?

Firmware development is not presented as a standard service. Customer firmware can be programmed or used for testing when the required files and method are supplied.

What testing methods are available?

Continuity, power checks, flying probe, ICT, or functional testing may be coordinated when suitable for the project. Coverage is not assumed from the method name.

What happens when a prototype fails?

The observed symptom, test condition, suspected cause, and next action are recorded so rework and design revision are not confused.

Can this lead directly into a small batch?

Yes, after the build package, open issues, sourcing choices, and test scope are reviewed and released.

Prototype and test

A prototype is useful when it answers the next question.

PCBLaunch connects prototype assembly with a test plan so the first boards produce evidence, not just a shipment of parts.

Define the proof

Separate manufacturing checks from product behavior and agree what the first build must demonstrate.

Build under a scope

Coordinate board assembly, programming, fixtures, and the conditions needed for repeatable checks.

Record the finding

Keep failures, changes, rework, and acceptance evidence visible before the next revision is released.

What the first boards should answer

Use the prototype to remove uncertainty, not just to show activity.

Each build should connect an observed result to a decision: change the layout, approve the behavior, investigate the assembly, or move to the next revision.

Evidence travels with the revision

Setup, inputs, observations, failures, rework, and acceptance are recorded against the board that was actually tested.

Start with the files, board, or prototype you already have.

PCBLaunch will identify the next questions before a build scope is agreed.
