Part Audit Review
Thought for 6 sec
I’ll audit the part metadata and existing assets, source the official datasheet if needed, update the Datasheet property, then compare symbol pins and footprint geometry against the manufacturer documentation.

- MPN: SWDP.2458.15.4.A.02
- Manufacturer: Taoglas Limited
- Function: Embedded dual-band Wi-Fi ceramic patch antenna
- Mounting: SMD
- Nominal body size: 15 × 15 × 4 mm
- Terminal count: 10
- Official datasheet: https://www.taoglas.com/datasheets/SWDP.2458.15.4.A.02.pdf

The Datasheet property was not changed because a URL is already populated. The existing link is a distributor product page rather than the official manufacturer PDF.

Datasheet key specifications
Pin cross-check
The manufacturer pin table defines:
- Pin 1: RF FEED, 50 Ω
Audit complete. The part is not safe to use as-is: the datasheet specifies pin 1 as RF feed, but the symbol/footprint maps FEED to pin 9; pad sizes also differ from Taoglas’s recommended land pattern. Metadata incorrectly classifies it as a logic AND IC.
The Datasheet property was already populated, so it was not changed, though it links to Arrow rather than the official Taoglas PDF. Full specifications and findings are in the Part Audit Report; I also filed an internal part-quality report.

Pin cross-check
The manufacturer pin table defines:
- Pin 1: RF FEED, 50 Ω
- Pins 2–10: Ground
The datasheet text says “8 pins,” but immediately lists pins 1 through 10; this appears to be a manufacturer-document typo. The mechanical footprint and pin table clearly show ten terminals.
Current symbol/terminal mapping
- Pin 9 is named FEED.
- Pin 1 is named GND_1.
- Pins 2–8 and 10 are ground-named.
- Every terminal has Pin Type: Unspecified and lacks a useful functional pin description.
Critical mismatch: the RF feed is assigned to pin 9 instead of pin 1. This makes the symbol-to-footprint mapping electrically incorrect.
Footprint cross-check
Correct aspects
- Ten copper pads are present.
- Pad center pitch for the eight main pads uses the expected 5.5 mm grid.
- Fabrication outline is 15 × 15 mm, matching the nominal antenna body.
- A STEP model is attached.
Mismatches
- Wrong feed pad number: footprint pad 9 is mapped to FEED, while the datasheet requires pad 1 to be RF FEED.
- Wrong main-pad size: pads 1–8 are 4.0 × 4.0 mm; the manufacturer footprint specifies eight 3.0 × 3.0 mm pads.
- Wrong small-pad size: pads 9–10 are 1.0 × 1.0 mm; the manufacturer footprint specifies two 0.8 × 0.8 mm pads.
- Potential solder-mask/paste noncompliance: all pads currently use matching copper, paste, and mask apertures. The manufacturer PCB-layout figures should be followed exactly, including any stated clearance or optional-pad treatment.
- Courtyard asymmetry: the current courtyard extends from −9.7 to +8.5 mm in X, which is not centered on the 15 mm body and is not identified in the datasheet as a required placement boundary.
Symbol assessment
The symbol exposes ten terminals, but the feed/ground assignment is wrong and terminal descriptions/types are not useful. Recommended terminal metadata:
- Pin 1:
RF_FEED, passive/RF input, “50 Ω antenna feed” - Pins 2–10:
GND, power/ground or passive as appropriate, “Antenna ground terminal”
3D model assessment
A STEP asset is present (
SWDP.2458.15.4.A.02_Web.STEP) at zero offset, unit scale, and zero rotation. The available structured layout data does not expose measured model extents, so exact 15 × 15 × 4 mm dimensional alignment and pad registration could not be conclusively verified in this audit.Overall disposition
Not safe to use as-is. The feed terminal is mapped to the wrong physical pad, and the land-pattern pad sizes differ materially from the manufacturer recommendation. Correct the symbol/terminal mapping and footprint before using this part in a PCB design. The classification metadata should also be changed from logic IC to RF antenna.
