Reel orientation: stated in the datasheet, missing on the page

Drew Owens · 14d ago ·closed by Colby Knox

Found by the Puma assembly sim's rotation check (ROT), ADVISORY. Sim-director checkpoint c2, 2026-10-28.

Finding: Reel orientation missing. The nametag first article (2026-09-21) placed it 180° off with carrier Orientation 0

Evidence (the datasheet on this page): p. 2 Detail E: tails on the trailing side, mouth toward "Direction of Unreeling"

Suggested addition to the page: Reel: mouth leading (toward the feed), tails trailing, 24 mm tape, 12 mm pitch; Puma carrier Orientation 180 with this package

Why it matters: the Puma's carrier Orientation for this part has to match how it sits in the tape. If it does not, a polarised part is placed rotated. The nametag first article on 2026-09-21 placed its USB-C 180 degrees off this way. Angles are in the tape frame: 0 means toward the direction of feed, 90 toward the sprocket holes, viewed from the cover tape. EIA-481 quadrants are as TI draws them, Q1 upper-left with the holes on top and the feed to the right.

Record: puma-sim data/reel-orientation (private drew2/adom-aiflow-assembly, not released yet). Nothing on this page was edited.

Added to the page: a Tape and reel section and a Packaging row in the key specifications.

  • Checked against the GCT drawing p. 2, Detail E (the crop is now on the page): the mating face (mouth) leads, toward the direction of unreeling, and the contact tails trail. 330 mm reel, 1,200 per reel, 24 mm tape, 12 mm pitch.
  • The Puma setting is there as you gave it: carrier Orientation 180 with this footprint, with the tape-frame angle convention and the 2026-09-21 nametag first article as the reason. That part comes from your sim; I checked the tape orientation against the drawing, not the machine mapping.

Closing; reopen if the sim wants it in a structured field instead of the README.
