  420. # Note: the signal pads are enlarged by 0.2 mm and their center is shifted by
  421. # 0.1 mm with respect to the reference.
  422. #
  423. # According to the data sheet, the leads terminate at (2.00+/-0.10 mm)/2+
  424. # 2.48 mm = 3.48+/-0.10 mm from the center. The reference footprint puts the
  425. # edge of the pads at (2.00+/-0.10 mm)/2+2.6 mm = 3.6 mm+/-0.10 mm, so the
  426. # maximum lead end could be at 3.58 mm while the minimum pad edge could be at
  427. # 3.5 mm.
  428. #
  429. # Assuming that the pad is intended to extend a bit beyond the lead, we need
  430. # to add 0.2 mm to compensate for these tolerances. (The pad tolerance may not
  431. # be intended to be used this way, however, we still have to consider small
  432. # errors in registration, which also amount to about 0.1 mm, so the calculation
  433. # remains valid.)
