Recommended PCB land pattern (C029XX; Male Vertical Surface Mount Double Row — M50-360)
  • Available sizes (without posts) include 12-way per row (matches M50-3600642)
  • Without posts — dimensions provided:
    • A = 1.27 × (number of contacts per row)
    • B = 1.27 × (number of contacts per row − 1)
    • Pad size: 0.40 mm square
    • Key dimensional callouts present: 0.80, 1.00, 1.27, 1.68, 2.62, 3.00, 3.40, 5.50, 6.50 mm (refer to drawing for their placements)
  • With posts (not applicable here based on the part number) — additional drill dimensions provided (Ø0.70, Ø0.95, etc.)
Special notes
  • Pin numbering convention not explicitly text-described on the product page; refer to the technical drawing for the pin 1 corner and numbering direction.
  • Solderability and heat resistance (EIA-364-52A / -56D): Others: 245°C for 5 s (solderability); 260°C for 10 s (heat resistance)
Step 4 — Cross-check symbol and footprint against the datasheet
Schematic symbol
  • Pin count present: 12 terminals are present:
  • Pin numbering: Each terminal’s “Pin Number” property is set to 1..12, matching a 12-contact (6+6) connector.
  • Pin types: All terminals have “Pin Type: Unspecified”. For a connector, these should be set to Passive to avoid ERC noise.
Footprint
  • Pad count present: 12 pads are present (Pads 1..12), consistent with a 6+6 DIL SMT header.
  • Footprint style: Only SMT pads are present; no post holes visible, which matches “without posts” for this specific MPN.
  • Pad size and pitch: The API did not return pad geometry (sizes/coordinates), so I cannot directly verify:
    • Pad size equals 0.40 mm square (as recommended).
    • In-row pitch equals 1.27 mm and row spacing equals 1.27 mm.
    • Inter-row and end-to-end spacing per “A” and “B” formulas for 6 contacts per row: A = 1.27 × 6 = 7.62 mm; B = 1.27 × (6 − 1) = 6.35 mm.
  • Pin 1 indicator: Not visible via the API. Ensure the footprint has a clear Pin 1 mark that matches the technical drawing.
Flags and actionable checks
  • Pin types: Set all schematic pins to Passive. Current state is Unspecified on 112.
  • Pin numbering/orientation: Confirm that the symbol’s left/right columns and the footprint’s numbering orientation match the technical drawing’s Pin 1 corner and numbering order.
  • Pad geometry: Verify pad size (0.40 mm square), pitch (1.27 mm), and row spacing (1.27 mm) against the recommended pattern in the C029XX spec. The current API view doesn’t expose pad coordinates/sizes; please double-check in the footprint editor.
  • MPN correctness vs features: M50-3600642 implies double-row SMT, 6 ways per row (total 12), gold on contact / tin on tails, without posts. Ensure no post holes in the footprint (current layout shows none — OK).
  • Mating pin height: 3.00 mm per product page — not enforced by PCB footprint, but good to confirm the mechanical height in your 3D/assembly constraints.
If you want, I can:
  • Update all schematic pin types to Passive for 112.
  • Add a brief part-level note with the key C029XX electrical ratings to the project properties for quick reference.
  • Help verify/adjust footprint pad sizes and row spacing to match the C029XX recommended pattern.
