Pad size

amerdsp

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.
