FOUR LAYERS. ONE CONNECTED PROCESS.Preparing your design files
A clear path from files to an agreed build

How It Works: From PCB Inquiry to Approved Scope

A PCB inquiry should lead to a shared definition of what will be built and how it will be accepted. Start with the files and requirements available, resolve the open engineering questions, and preserve the approved revision. The steps below explain the information flow; project dates and process availability require confirmation for the actual scope.

Discuss your requirements ↗

1. Describe the project and the requested delivery

State whether you need bare boards, assembled boards or review of a broader integration scope. Include the application, quantities, design stage and desired milestone. Describe any constraint that affects feasibility, such as connector fit, controlled impedance, a specified material or a required inspection record.

If the design is unfinished, say what is fixed and what remains open. A placement proposal can support an early discussion, while a production quotation needs a sufficiently defined release package. The aim of the first submission is to expose the important questions, not to disguise uncertainty behind guessed specifications or an outdated file set.

Illustrative workflow. The agreed scope and acceptance criteria define each project.

2. Attach one coherent revision package

For fabrication, provide copper and mask outputs, drill data and a fabrication drawing. For assembly, add a BOM with exact part numbers, placement coordinates and assembly instructions. Include programming, test or mechanical files when those tasks are requested.

Use clear revision identifiers and explain any differences between files. Remove superseded alternatives from the active package or label them unmistakably. If a requirement appears only in an accompanying message, transfer it into the controlled documentation before release. The project should not depend on someone remembering which of several conflicting notes was intended to be final.

3. Resolve engineering questions explicitly

A review may identify missing information, contradictory notes or a feature that needs a different construction. Each question should lead to an explicit answer: retain the requirement, approve a defined alternative, revise the files or hold the issue open. Explain the purpose of a critical requirement so that alternatives can be assessed against the same goal.

Keep the answer tied to a revision and affected feature. An approval to adjust one impedance structure is not unrestricted permission to alter the entire layout. If the response changes the design, update dependent drawings, assembly files and validation plans before treating the review as closed.

4. Confirm scope, evidence and milestones

Review what the proposed build includes: material, construction, finish, quantities, assembly responsibilities and testing. Identify the records required at delivery and any customer-supplied parts, fixtures or firmware. A useful quotation has a clear technical basis rather than relying on unspecified standard options.

Separate a requested date from a confirmed project commitment. Engineering closure, material decisions and supplied inputs can affect the schedule. Record those dependencies and who owns each one. If the scope changes, revisit the commercial and scheduling assumptions instead of assuming that an earlier proposal applies unchanged to a different build.

5. Release, verify and preserve the learning

Release one approved package and keep a copy of the accepted decisions. Define how later changes will be reviewed and identified. For prototype work, state the validation questions the delivered boards must help answer; for production, define the agreed repeatable checks and required records.

After evaluation, document what worked, what changed and what remains unresolved before the next order. Review file preparation, DFM review and first-article planning for detail. Learn more about the site’s approach, or submit the package through Request a Quote to begin a project-specific review.

Frequently asked questions

Can I request a quotation with draft files?

Yes, if the draft status and open decisions are clear. The quotation basis may need revision when construction, components or scope changes, and production requires an approved release package.

What if I revise a file after submitting the inquiry?

Identify the new revision and summarize the changes. State which files it supersedes so engineering can reassess affected answers and avoid mixing old and new instructions.

Does completing a checklist mean the board is approved?

No. It organizes your self-review and submission. Manufacturing approval depends on the actual files, resolved engineering questions and agreed project requirements.

When is a requested delivery date confirmed?

It must be evaluated against the agreed scope and dependencies. A date entered in an inquiry is a planning requirement, not an automatic commitment to manufacture or deliver.

What should be retained for a repeat order?

Keep the approved fabrication and assembly files, revision identifiers, accepted changes, component and firmware definitions, and relevant validation or inspection records. Review any new changes before repeating the build.
