Part Metadata Review and Datasheet Update
Worked for 4 mins 12 sec
Reviewed the Hirose DF30FC-20DP-0.4V(81) part and created a detailed report: Part Review: Hirose DF30FC-20DP-0.4V(81).
Summary: metadata and 20-pin symbol match the datasheet; the existing datasheet URL was already set, though it’s an uploaded copy rather than the official Hirose URL. Main flags are missing explicit pin descriptions and footprint pad geometry not being fully exposed for exact land-pattern verification.
Add Contact 1 through Contact 20 descriptions to the symbol terminals.
Thought for 6 sec
I’ll add clear
Contact 1 through Contact 20 descriptions to the 20 symbol terminals, then verify the properties were applied.Worked for 33 sec
Added
Pin Description values Contact 1 through Contact 20 to all 20 symbol terminals and verified they are present.Open items:
- None.
Suggested next steps:
- Set all terminal pin types to a consistent passive/unspecified convention.
- Re-run the part review checks.
- Verify footprint land-pattern dimensions against the Hirose drawing.

A datasheet URL was already present, so I did not change the part property. I also found the official Hirose catalog URL for reference:
https://www.hirose.com/en/product/document?clcode=&documentid=D48588_en&documenttype=Catalog&lang=en&productname=&series=DF30.Datasheet source used
- Hirose DF30 Series catalog, 0.4 mm pitch, 0.9 mm height board-to-board / board-to-FPC connectors.
- The project’s attached datasheet content matches this DF30 family catalog.

Symbol / terminal review
- Schematic symbol contains 20 Terminal components, numbered 1 through 20.
- Odd-numbered terminals are placed on the left side and even-numbered terminals on the right side, which is a reasonable logical representation for a double-row connector.
- All terminals currently have
Pin Type: Unspecifiedand no specificPin Descriptionproperty. - For this connector, individual contacts are electrically generic signal contacts, so unspecified/generic pin function is acceptable. However, adding descriptions such as
Contact 1throughContact 20would improve library clarity.
Footprint review
- Layout contains 20 pad nodes with designators 1 through 20, matching the datasheet contact count.
- The footprint has a top silkscreen outline and pin-1 marker, and the visible outline is approximately 5.14 mm wide, matching the datasheet A dimension for the 20-position header.
- The layout inspection tree exposed pad node identities but did not expose detailed pad geometry/size/layer values in the available output, and the flat SVG did not render copper pad shapes. Because of that, exact pad size, pad pitch, and land-pattern geometry could not be fully verified from the available tool output.
Mismatches / issues flagged
- Datasheet property is not the official Hirose URL: a datasheet URL is present, but it points to an uploaded storage copy rather than the official Hirose document URL. The user condition said to search/update only if no URL was already set, so I left it unchanged.
- Missing pin descriptions: terminals 1–20 have no explicit contact descriptions. This is not electrically wrong, but adding
Contact 1…Contact 20would make the symbol more complete. - Pin type left unspecified: acceptable for a passive connector contact, but setting all pins to passive/unspecified consistently is recommended depending on Flux library convention.
- Footprint pad geometry not fully inspectable: 20 pads are present and overall outline appears consistent, but detailed copper pad dimensions could not be cross-checked from the returned layout data.
Overall result
The part metadata, pin count, connector type, mount style, and general footprint outline are consistent with the Hirose DF30FC-20DP-0.4V(81) datasheet. No critical mismatch was found in MPN, manufacturer, contact count, or connector family. The main cleanup opportunities are replacing the uploaded datasheet URL with the official Hirose catalog URL, adding explicit pin descriptions, and verifying/exposing exact pad land-pattern geometry.
