I created the detailed part review report and filed an internal quality report for the likely footprint/symbol issues.

flux

Completed the review and set the part’s Datasheet URL to the official Amphenol RF customer drawing. The main issues found are incomplete symbol pin metadata and a likely footprint defect: pads 4/5 appear duplicated on the top layer instead of being bottom-side shield pads.
Open items:
Suggested next steps:
  1. Update terminal descriptions/types for RF signal and shield/ground pads.
  2. Correct the footprint pad layers and verify top pad length against the drawing.
  3. Add an explicit 0.085 in / 2.16 mm PCB thickness note to the part metadata.

Official PCB Layout Details Extracted
The Amphenol drawing shows separate top and bottom recommended PCB layout views:
  • Top view:
    • Three top-side copper features.
    • Center feature width: 1.50 mm.
    • Two side feature widths: 1.80 mm.
    • Side pad centers are approximately +/-4.25 mm from the center feature, giving 8.50 mm side-to-side spacing.
    • Top features are called out with 3 x 5.50 mm and 3 x 0.50 mm dimensions on the drawing.
  • Bottom view:
    • Two bottom-side side pads.
    • Each bottom pad: 1.80 mm wide x 5.00 mm long.
    • Bottom pad spacing: 8.50 mm.
Current Schematic Symbol Check
Current schematic uses five terminal components numbered 1 through 5:

Table

TerminalCurrent metadataExpected interpretation
1Pin Type: Unspecified; no descriptionCenter contact / RF signal
2Pin Type: Unspecified; no descriptionShield/body/ground, likely top-left ground pad
3Pin Type: Unspecified; no descriptionShield/body/ground, likely top-right ground pad
4Pin Type: Unspecified; no descriptionShield/body/ground, likely bottom-left ground pad
5Pin Type: Unspecified; no descriptionShield/body/ground, likely bottom-right ground pad
Five terminals are defensible if the part intentionally exposes all five physical solder features so designers can connect all ground/shield pads explicitly. However, the current symbol is incomplete because all pins are Unspecified and lack pin descriptions. For this connector, terminal 1 should be labeled/described as RF signal or center contact, and terminals 2-5 should be labeled/described as shield/body/ground contacts, normally with Passive electrical type.
A two-terminal schematic abstraction would also be acceptable if all four shield pads map to a single ground/shield terminal in the footprint, but the current five-terminal approach requires clear pin descriptions and expected same-net usage.
Current Footprint Check
Current KiCad footprint payload contains:

5(4.2418, -1.265) mm1.8034 x 5.0038 mmF.Cu / F.Paste / F.Mask
Matching aspects:
  • Pad widths are close to the drawing values: 1.4986 mm ~= 1.50 mm and 1.8034 mm ~= 1.80 mm.
  • Side pad spacing is close to the drawing: +/-4.2418 mm ~= +/-4.25 mm, or 8.4836 mm side-to-side ~= 8.50 mm.
Mismatches / concerns:
  1. Pads 2 and 4 exactly overlap on the same F.Cu layer, and pads 3 and 5 exactly overlap on the same F.Cu layer. This is a strong footprint defect.
  2. Based on the official top/bottom drawing, pads 4 and 5 likely represent the two bottom-side shield/body pads and should be on B.Cu/B.Paste/B.Mask, not duplicated on F.Cu.
  3. Current pad length is about 5.00 mm for every pad. The drawing appears to call out 5.50 mm top-side features and 5.00 mm bottom-side features, so the top pads may be 0.50 mm short or missing a drawing-specified extension/feature.
  4. The footprint includes an Edge.Cuts line inside the footprint. This may represent the PCB edge/reference for the end-launch geometry, but it should be verified because board-edge geometry is critical for SMA launch fit and RF performance.

AreaStatusNotes
MPNPass132255-11 matches official Amphenol part.
ManufacturerPass after current metadataOfficial manufacturer is Amphenol RF, not AMP/TE. Any old CONN_132255-11_AMP naming is misleading.
DescriptionPass after current metadataCurrent description aligns with official product page.
Pin countConditionalFive terminals can match five physical solder features, but logical connector function is signal + shield.
Pin descriptionsFail / incompleteTerminals are Unspecified and undescribed.
Footprint pad widths/spacingMostly passWidths and spacing are close to official drawing.
Footprint pad layersFailPads 4/5 likely should be bottom pads; current pads duplicate top pads 2/3.
Footprint pad lengthNeeds verification / likely mismatchCurrent all-pad length is ~5.00 mm; official top features appear to be 5.50 mm.
Board thickness constraintNeeds metadata/use noteIntended for 0.085 in / 2.16 mm PCB thickness.
Actions Taken
  1. Correct the footprint so pads 4 and 5 are bottom-side shield/body pads if the five-terminal mapping is retained.
  2. Verify top-side pad length against the Amphenol drawing and update top pad geometry if the required length is 5.50 mm.
  3. Update symbol pin metadata:
    • Pin 1: Center Contact / RF Signal, Passive.
    • Pins 2-5: Shield / Body / Ground contacts, Passive.
  4. Add a note/property making the 0.085 in / 2.16 mm PCB thickness requirement explicit.
  5. Replace misleading legacy naming such as CONN_132255-11_AMP with Amphenol RF / SMA end-launch terminology where possible.
