In Rules "Pad to Pad" spacing = 0.15mm But pads were trimmed and now Pad1 to Pad2 space=0.33mm  |

The Pad Stack Rules are intended for medium to large packages. You can't have a pin pitch of 0.175 when the maximum lead thickness is 0.23. That's impossible. Turn the minimum pad to pad off for micro-miniature packages. The pin pitch is 0.175. This can't be true. The pin pitch is between the Center of the Body and the center of the pin. You need to double to pin pitch to 0.35 mm. But I would also change the solder joint goals downward slightly.

This package in not a SOTFL. The SOTFL component family has the Terminal Lead Width the same size for all leads. This JEITA-SC-1168B case code is none standard and must use the mfr. recommended footprint. Package:  Mfr.
