PCB & assembly Guides - Page 2

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.

Specify flex PCB stiffener material, location and total insertion thickness to prevent connector-fit and assembly-handoff mistakes.

Define a flex PCB bend with its use case, geometry and motion requirements so the construction can be reviewed before manufacture.

Prepare an RF PCB material request with an exact laminate grade, dielectric thickness, copper details and approved substitution rules.
