PCB Communication & Stakeholder Relations 2

Question 1

A mechanical engineer requests a PCB outline change after the layout is 80% complete. What is the best first step?

Accepted Answer

Assess the impact on component placement and routing before responding

Answer

Performing an impact assessment first allows you to communicate realistic schedule and cost consequences to the stakeholder.

Question 2

Which document is most effective for aligning all stakeholders on PCB design requirements at the start of a project?

Accepted Answer

Design Requirements Document (DRD) or design specification

Answer

A Design Requirements Document captures electrical, mechanical, thermal, and compliance requirements agreed upon by all parties before design begins.

Question 3

A firmware engineer tells you a GPIO pin assignment must change. At what design stage does this change have the lowest cost?

Accepted Answer

During schematic capture, before layout begins

Answer

Pin changes during schematic capture require only a net rename, whereas post-layout changes may require rerouting multiple signals.

Question 4

What is the primary purpose of a Design Review (DR) meeting in a PCB project?

Accepted Answer

To identify design issues and obtain stakeholder sign-off before advancing to the next phase

Answer

Design reviews serve as formal checkpoints where cross-functional stakeholders verify the design meets requirements before costly downstream steps.

Question 5

A procurement team asks why a specific capacitor brand was specified. What should the PCB designer provide?

Accepted Answer

A justification citing electrical parameters, footprint, and qualification status

Answer

Providing a technical justification helps procurement find qualified alternates while preserving the design intent.
