Communication & Stakeholder Relations Flashcards

A test engineer reports that test probe access is blocked by a component added late in layout. How could this have been prevented?

Answer: By involving test engineering in early design reviews and sharing testability requirements upfront

Early cross-functional collaboration ensures testability requirements such as test point placement are incorporated before the layout is locked.

What information should a PCB designer include when escalating a component obsolescence issue to the supply chain team?

Answer: The part number, last-time-buy date, affected assemblies, and potential drop-in replacements with electrical comparison

A complete escalation package enables supply chain to make informed procurement decisions and evaluate alternatives without repeated back-and-forth.

During a design handoff, the fabrication house asks for clarification on controlled impedance tolerances. Who should the PCB designer consult?

Answer: The signal integrity engineer or the originating electrical engineer who specified the impedance requirement

Impedance tolerances are set by electrical performance requirements, so the originating engineer must confirm acceptable tolerances before instructing the fab.

A regulatory compliance team asks whether the PCB design meets RoHS requirements. Which document best answers their question?

Answer: The Bill of Materials with RoHS compliance status listed for each component

RoHS compliance is material-based and must be documented component-by-component in the BOM with supplier-provided compliance declarations.

A stakeholder from marketing requests a new board color for aesthetic reasons. What should the PCB designer do?

Answer: Evaluate whether the color change affects cost, lead time, or performance before committing

Non-standard solder mask colors may affect fab lead time and cost and should be evaluated holistically before being agreed upon with the stakeholder.

What is the best way to communicate net impedance requirements to a PCB fabrication house?

Answer: A controlled impedance specification table in the fabrication drawing, referencing specific trace layers and target impedance values

Formal written specifications in the fab drawing create an auditable record and ensure the fab designs the stackup to meet exact impedance targets.

A hardware manager wants weekly status updates on the PCB layout. Which format provides the most useful snapshot?

Answer: A brief summary covering routing completion, open DRC violations, pending decisions, and schedule status

A concise status summary focused on key metrics and blockers lets management quickly assess progress and identify where decisions are needed.
