Planning project updates.

Reviewing the bill of materials.

Analyzing the schematic.

Looking for "Manufacturer part number, manufacturer name, product description, package/mechanical style, plating, circuit count, row count, differential pair count, connector height, mounting style, current rating, voltage rating, temperature range, insulation resistance, dielectric withstanding voltage, contact resistance, durability, and any key specifications from the first pages/specification tables." in 2034560003_sd.pdf

Looking for "Complete pin / signal assignment information for the 699-circuit Mirror Mezz connector, including whether the datasheet provides a pin map, contact naming convention, row naming, and any notes needed to verify symbol pin descriptions." in 2034560003_sd.pdf

Looking for "Mechanical package details and footprint-related information: recommended land pattern, BGA attach details, dimensions, pitch, rows, columns, and any package or PCB layout notes needed to verify the footprint." in 2034560003_sd.pdf

Review Summary
I reviewed the current part metadata, the official Molex datasheet, the symbol terminals, and the footprint/layout representation.
Datasheet property
  • No web search was needed
  • The project already has Datasheet URL set to the official Molex PDF:
    • https://www.molex.com/pdm_docs/sd/2034560003_sd.pdf

Symbol audit

What matches

CheckResult
Terminal count699 terminals present
Pin-number populationThe sampled terminals all have Pin Number populated
Pin naming styleUses alphanumeric grid IDs like A11, F65, J34, which matches the datasheet convention
Ground-style labelsGND_xx labels still map to coordinate-based Pin Number values, which is acceptable if intentional

Problems flagged

IssueResult
Pin Type coverageAll sampled terminals are still Pin Type = Unspecified
Pin Description coverageI did not find populated per-pin descriptions in the visible terminal properties
Semantic pin descriptionsThe datasheet does not provide unique functional names for every contact; it mainly provides coordinate IDs and mirroring, so full semantic pin descriptions cannot be derived directly from this datasheet alone
Symbol naming consistencySome designators are coordinate IDs, while others are GND_xx; that is a mixed labeling style
Interpretation
  • The symbol appears structurally complete because the 699-pin count matches the datasheet.
  • The pin identifier scheme is aligned with the datasheet's row/column naming.
  • The main symbol-quality issue is metadata completeness, not missing pins:
    • Pin Type is not classified
    • Pin Description appears missing
    • labeling style is inconsistent between coordinate pins and GND_xx pins
Footprint audit

What matches

CheckResult
Footprint asset existsYes, a KiCad footprint asset is present
Layout pad count699 pads
Connector styleBGA/solder-ball style representation is consistent with datasheet
Datasheet pad-field expectationDatasheet calls for 699X pads / mask apertures

Datasheet footprint details to verify against the asset

Datasheet itemValue
Recommended pad diameter0.50 ± 0.05 mm
Solder mask aperture0.60 ± 0.05 mm
Pad styleNon-solder-mask-defined
Orientation anchorPin A3 explicitly identified
Array conventionRows A, B, C, D, E, F, G, H, J, K, L
Limitation
I could confirm:
  • a footprint exists,
  • the PCB representation has 699 pads,
  • and that this is directionally consistent with the datasheet.
I could not fully numerically verify pad diameters, pitch, and exact row/column geometry from the available project-tool output alone, because the current layout response does not expose the per-pad dimensions/coordinates in a usable way.

Symbol data

ImprovementRecommendation
Pin TypeClassify pins at least into Ground vs Unspecified/Passive where justified
Pin DescriptionAdd short descriptions if you have a pin-role source beyond this drawing
Label styleDecide whether all visible labels should be coordinate-based, or whether ground contacts should intentionally stay grouped as GND_xx
Bottom line
  • Datasheet URL: already correct, so no update was needed.
  • Part metadata: mostly right, but package and description wording should be tightened.
  • Symbol: pin count and coordinate naming look structurally correct, but terminal metadata is incomplete.
  • Footprint: 699-pad footprint is present and consistent at a high level, but I could not fully prove pad geometry against the drawing from the available layout output.
If you want, I can now fix the project metadata and terminal properties for this part.
