I-Pex Connector Verification


Read-only verify this 20455-030E-76 library connector for Chromebook eDP emulator. Official drawing https://www.i-pex.com/sites/default/files/downloads/pdf/2D_CABLINE-VS_RECEPTACLE_20455C30.pdf covers -12 and -76 geometry; web scrape suggests only shell gold thickness differs but erroneous scrape said pitch1.4mm (actual 0.5). Inspect schematic terminals, footprint physical pads vs official drawing (30 contacts pitch0.5mm, 4 shell pads), pad widths length orientation numbers and 3D existence. Fetch mechanical-mating-geometry skill. Report exact discrepancies and whether usable. Do not edit unless you own project and necessary; if editing publish corrected same-part version and report version. Prefer read-only evidence quick. User approved real exact connector creation if absent, but existing same mating -76 found. Need validate actual part footprint; no PCB in main board yet.
I’ll compare the connector’s terminals and physical footprint with the official I-PEX drawing, and check whether a 3D model is present. This review will be read-only.
Usable for schematic capture and PCB placement: all 30 passive terminals map to pads 1–30, with four separate shell terminals S1–S4; the footprint matches the official drawing: 0.50 mm pitch, signal pads 0.25 × 0.90 mm at KiCad coordinates x = −7.25…+7.25, y = −1.92 mm; small shell pads 0.55 × 0.90 mm at (±8.15, −1.92), and large shell pads 1.40 × 1.90 mm at (±10.35, +0.90), with pin 1 on the left in the drawing’s top view.
No copper-geometry or numbering discrepancy found; however, all four shell symbol pins share the same symbol position, and the imported courtyard geometry appears in the active “Silk Shapes” asset, so schematic shell connectivity and manufacturing silkscreen need attention before release.
An active 20455-030E-76.step model exists with position (0, −0.5, 0) mm and rotation (90°, 180°, 0°), but its physical alignment was not verified; I made no edits or publication, as this project is view-only.
