10164227-1001A1RLF

"""AI-created simplified 3D model of Amphenol 10164227-1001A1RLF (BergStak 0.40 mm board-to-board
receptacle, 100 positions, 1.5 mm stack, no hold-down), built from Amphenol drawing
10164227 rev C, sheet 1 (body A = 22.60, contact span B = 19.60, width 3.00 body / 3.38 over tails,
height 1.45, contact pitch 0.40, tail width 0.12, tail coplanarity 0.05).

Frame: Adom Z-up, millimetres, seating plane z = 0 (contact tails), origin = body centre, which is
also the footprint origin. Model y = -(KiCad y). Pad n of the footprint is at KiCad
x = 9.8 - 0.4 * floor((n - 1) / 2), odd pads at KiCad y = -1.32 (model y = +1.32), even at +1.32.

Simplifications: the housing is a box with one mating cavity and a split central island; contacts are
drawn as a tail on the board plus a strip on the cavity wall; no moulded marks (the drawing does not
tie any marking to a contact number).

Run: python 10164227-1001a1rlf_model.py <out.step>   (see the modes at the end)
