Mini USB Footprint Qualification

Thought for 4 mins 19 sec

Qualified the active source part against the Same Sky drawing. No edit/version was published because this project is view-only. Terminal mapping is preserved and correct: pins 1–5 plus shell terminals SH1–SH4.

Table

Feature	Same Sky drawing	Actual footprint	Result
Signal pads	5 × 0.50 × 2.50 mm	5 × 0.50 × 2.50 mm	Pass
Signal pitch	0.80 mm, 3.20 mm span	0.80 mm, 3.20 mm span	Pass

Shell row spacing	5.48 mm	5.48 mm	Pass
Alignment holes	2 × Ø0.90 mm	2 × Ø0.90 mm NPTH	Pass
Hole spacing	4.40 mm	4.40 mm	Pass
PCB-edge datum	7.85 mm from signal-pad row	Edge rule: 8.50 mm	Fail: +0.65 mm
Connector face height	3.96 mm; opening reference 3.10 mm	Mechanical-model item	Drawing qualified
Maximum insertion/body length	9.80 mm max	Mechanical-model item	Drawing qualified
General tolerance	X.X ±0.38 mm; X.XX ±0.25 mm	—	Recorded

The footprint’s own fabrication line marks PCB EDGE at 7.85 mm, corroborating the manufacturer datum; only edgePlacementOffset is inconsistent.

Exact repair

In the editable source part, set on footprint UID:

Text
95853830-701a-46b6-8e35-d43b7ae6771c.defaultFootprint
edgeDirection = 180°
edgePlacementOffset = 7.85 mm

For a consuming-project override, create a selector ruleset targeting the connector footprint:

JSON
{
  "mode": "create_ruleset",
  "name": "UJ2-MBH PCB edge datum correction",
  "selector": "#J1 footprint",
  "rules": {
    "edgePlacementOffset": "7.85mm !important"
  }
}

Replace J1 with the placed connector’s designator. Do not alter pads, holes, or terminal mapping. An internal source-part quality report was filed for the 0.65 mm edge-datum defect.
