THE PRACTICAL ANSWER

What to know before you decide

PCB capability is the combination of features a manufacturing process can deliver together, with an agreed acceptance method. A minimum trace width, smallest drill and maximum copper weight taken from separate examples may not describe a feasible board. Use this page to organize the dimensions, materials and evidence that a reviewer needs. The figures for your project should come from a written construction proposal; this website does not publish unverified equipment limits or factory performance claims.

01 / DECISION GUIDE

Make the trade-offs explicit

Review the combined construction

Start with layer count, finished thickness, material family and copper requirements. Add the smallest trace, clearance and finished hole, identifying where they occur. Ask whether those features can coexist in the proposed construction. A local dense region may justify a targeted layout change, while a feature repeated throughout the board can affect the entire manufacturing route and commercial offer.

Distinguish drawing intent from process terminology

Finished hole diameter is not the same thing as the production drill choice, and external finished copper needs a different conversation from starting foil. Specify what the delivered board must achieve and allow the fabricator to explain its process. Where the interpretation changes fit, current capacity or assembly, record the agreed meaning in the fabrication notes before release.

Ask for relevant acceptance evidence

An advertised capability does not by itself state how the delivered lot will be assessed. Identify dimensions, electrical test scope and any specific measurement records that matter to your receiving process. Ask for the proposed acceptance criteria and reporting format with the quote. This avoids requesting an unavailable report after production or assuming that a generic pass statement covers a critical feature.

Keep standard and exceptional features visible

List edge plating, controlled-depth operations, slots, special finishes and controlled impedance separately from the basic board specification. Give each feature a drawing reference and an approval owner. When comparing suppliers, ask them to list deviations and process assumptions explicitly. A lower price is meaningful only when the accepted construction and evidence are comparable across the proposals.

Evidence	Receiving inspection and repeat builds	Lot identity and agreed measurements

03 / REVIEW BEFORE RELEASE

Questions that prevent rework

Combining unrelated minimums

Confirm the whole feature set with the proposed construction rather than assembling a specification from separate best-case examples.

Using typical as a guarantee

State the required delivered tolerance and ask for written confirmation. Typical values are not an acceptance specification.

Leaving exceptions off the RFQ

A small special feature can add an operation. Identify it before price and lead-time assumptions are finalized.

04 / COMMON QUESTIONS

Get a clear answer

Where are the minimum trace and drill limits?

They need confirmation for the actual material, copper and construction. Submit the relevant features and drawing locations for review. Publishing a single universal minimum would hide dependencies and could lead to an unsuitable release decision.

What is the difference between capability and acceptance?

Capability describes what a process is proposed to produce. Acceptance defines how the delivered result will be judged. Both need to be clear: a supplier may offer a feature without including the exact measurement record your project requires.

Can I request a capability review before layout is complete?

Yes. Early discussion is particularly useful for dense packages, unusual thickness or interconnects. Provide the intended constraints and identify which remain flexible. Confirm the final exported design again before production because an early review is not approval of later changes.

Technical references

Check each source’s scope and revision against your project requirements. Confirm the proposed construction with your manufacturing partner.
