Schematic Symbol Cross-Check
Observed symbol contents:
- 16 terminal objects total.
- Circuit terminals numbered 1 through 14 are present.
- Two mechanical / solder tab terminals are present as MP_1 and MP_2 with pin numbers 15 and 16.
- Symbol pin order is sequential for contacts 1–14, with mounting pads separated on the opposite side.
- Terminal
Pin Type is set to Unspecified for all pins.
- No terminal-level
Pin Description properties were found.
Assessment:
- Pin count / terminal count: Matches the expected practical representation: 14 electrical circuits plus 2 solder tabs / mounting pads = 16 PCB pads.
- Circuit numbering: Matches the datasheet’s 14-circuit header concept and No. 1 circuit marking.
- Pin descriptions: Incomplete. Contacts 1–14 should be described as electrical contact/circuit pins, and MP_1/MP_2 should be described as solder tab / mechanical mounting pads.
- Pin type:
Unspecified is acceptable for passive connector terminals, but more explicit terminal descriptions would improve reviewability.
Footprint Cross-Check
Observed footprint/layout contents:
- 16 pad nodes are present: pads 1–14 plus MP_1 and MP_2.
- Silkscreen/body outline spans approximately 16.8 mm wide, consistent with the datasheet B dimension for the 14-circuit normal type.
- The footprint includes a No. 1 indicator near the left side of the connector outline.
- The footprint includes board-side silkscreen/body geometry consistent with a right-angle side-entry header.
Assessment:
- Pad count: Matches expected 14 signal contacts + 2 solder tabs.
- Overall width: Appears consistent with datasheet B = 16.8 mm.
- Pin 1 marking: Present.
- Right-angle/side-entry outline: Present.
- Limitations: The available layout inspection did not expose detailed pad dimensions/centers for each pad, so I could not numerically verify every contact pad and solder-tab land dimension against the recommended PCB pattern. The visible outline and pad count are consistent.
Mismatches / Issues Flagged
- Missing pin descriptions — all terminal descriptions are blank/not present. Recommended descriptions:
- Pins 1–14:
Circuit contact 1 … Circuit contact 14, or equivalent.
- MP_1/MP_2:
Solder tab / mechanical mounting pad.
- Terminal pin types are all
Unspecified — not necessarily wrong for a connector, but review quality would improve if contacts are marked passive/unspecified consistently and mounting tabs are described as mechanical/solder tabs.
- Datasheet property is populated with an uploaded storage URL, not the official JST URL — this satisfies “datasheet URL is set,” but if the goal is to keep the official manufacturer URL directly on the part, update it to
https://www.jst-mfg.com/product/pdf/eng/eSHL.pdf.
- No BOM item shown — expected for a published part project composed of terminal primitives, not a board-level assembly issue.
- Part Type uses
Connectors plural — acceptable semantically, though some property systems prefer singular Connector.
Conclusion
The part broadly matches the JST SM14B-SHLS-TF datasheet: manufacturer/MPN, 14-circuit 1.00 mm SMT right-angle SHL header description, 16 total pads including solder tabs, and approximate footprint body width are consistent. The main cleanup item is metadata quality: add terminal pin descriptions and optionally replace the Datasheet URL with the official JST PDF URL.
