Findings
| Check | Status | Risk |
|---|---|---|
| Pin count: schematic vs footprint | Pass | Both show 5 connections/pads |
| Basic package style vs project description | Pass | Bulkhead / SMA / PCB through-hole aligns with retrieved data |
| Datasheet presence | Pass | Datasheet URL exists |
| Pin names / functional pin descriptions | Fail | Current symbol pins are effectively anonymous |
| Pin electrical types | Fail | All pins are Unspecified |
| Signal vs shield distinction | Fail | The symbol does not distinguish the center RF pin from the 4 shell/ground pins |
| Ordering / package metadata completeness | Partial | Project mount property says Axial, which does not match the retrieved product style well |
| Manufacturing footprint verification | Partial / Needs manual geometry check | I could confirm 5 pads exist, but not all exact hole diameters/XY geometry from the Flux footprint object dump |
- Highest risk: the symbol does not clearly identify which single pin is the RF center conductor and which four are shield/body ground tabs.
- This can cause incorrect schematic usage, wrong net assignments, and RF/grounding mistakes.
- High risk: all pins are marked Unspecified.
- For a connector part, the center contact should be treated as the RF/signal contact, while the outer tabs should be ground/shield/mechanical shell connections.
- Medium risk: the project property Mount = Axial does not appear consistent with the official part description, which is bulkhead rear-mount, straight, PCB through-hole SMA jack.
- That can lead to bad filtering/searching and possible ordering confusion.
- Medium risk: the current part data does not include a clear footprint metadata label like a package name or mounting pattern identifier.
- Open item: the footprint has the correct pad count, but I could not fully verify exact drill diameters and pad coordinates against the customer drawing from the current PCB object dump alone.
Recommended corrections
| Priority | Correction |
|---|---|
| 1 | Name the pins so the center pin is clearly the RF signal contact and the other 4 pins are shell/ground tabs |
| 2 | Set correct pin electrical types instead of Unspecified |
| 3 | Update the generic mount/property wording so it matches the official product description |
| 4 | Manually verify the footprint drill sizes and XY locations against the customer drawing before using this part in manufacturing |
- The part project is not yet safe as-is for production library use.
- The biggest issue is symbol semantics, not pad count.
- I do not see evidence of a catastrophic pin-count mismatch, but I do see enough ambiguity to cause wrong net assignment, poor RF grounding, or incorrect library reuse.
