What is good practice when you design a new package? Does the pad size
equal to the median mentioned in the datasheet or the maximum? If a
datasheet states that the pad width is 0.23 +.07 -.05 mm should my pad
be 0.3 mm?
Thank you

hi,
while designing a new package, i always be careful about drc violation.
If a pad width will not result a drc violation then it may be wide
different from the one specified in a datasheet. So, using the maximum
values for a pad will be a good choice. Yes, off course i this my opinion.

If it is a through-hole pad, I'd suggest that you take the maximum value
and even some 30% margin to have space for solder flow, while soldering.
If it is a SMD pad, I'd do it using maximum dimensions and increase it
50% 'outside' the component, to have space to heat the pad for reflowing.
