PCB & Manufacturing Guides - Page 3

Review PCB silkscreen for readable polarity, connector labels and revision marks without placing essential text on pads or under components.

Write a PCBA functional test specification with power conditions, firmware, measurable pass limits and a clear failure-recording process.

Plan accessible PCB test points for power, programming and diagnostics, with a clear probe-side and fixture review before assembly.

Prevent stencil mismatches by checking board versus panel data, assembly side, frame requirements and the approved panel revision.

Plan PCB and panel fiducials with the assembler, including visibility, component clearance and consistent board and stencil revisions.

Review PCB placement coordinates and component orientation using a common origin, explicit board sides and an assembly drawing before release.

Document do-not-populate parts and assembly variants so the BOM, placement data and drawings describe the same finished board.

Create a clear BOM substitution process that checks the exact part, package and design requirements before an alternative enters assembly.

Prepare a controlled-impedance PCB request with target values, layer references, geometry and a clear approval process for stackup changes.
