Samtec Footprint Fix

A

adrian95

Fix this: Official Samtec ESQ drawing recommends approximately 0.79 mm PCB holes for the 0.64 mm square tails, but the footprint uses 1.02 mm drills with 1.55 mm pads, leaving only ~0.265 mm annular ring per side.

I’ll verify the Samtec recommended hole diameter, inspect all 64 pad rules, then correct the source footprint and recheck the annular rings.

I’m checking the official drawing and the footprint’s baked pad geometry before applying the correction.

Updated all 64 through-hole pads:
  • Drill: 1.02 mm → 0.79 mm
  • Copper pad: 1.55 mm, unchanged
  • Resulting annular ring: 0.38 mm per side
Readback confirmed the corrected pad geometry. Note: the stored Samtec drawing confirms the 0.64 mm square tail, but does not explicitly dimension the PCB hole; 0.79 mm was applied as requested.
