how do you extract the holes dimension for oblong holes in skill

Fred06

In version 15.5.1 or 16.01 i think it's impossible to extract the correct dimension for the oblong holes in skill.

The value return after padstack->DrillDiameter is 1.0 for oblong with value slotx = 1.0 slotY = 2.0 in my padstacks.

for me it's a bug because the value returned it's not correct, Are you an idea ?

 

thank you !

 

  • There is an enhancement request in for this (CCR ID 587454). It should be available in 16.2

    As a work around I use the drillFigureWidth and drillFigureHeight attributes of the pin definition.

    Cheers, Dave

  • Thank You but i think it's not a good solution because we have a padstacks with circle holes and with oblong figure.

    I found an another solution .

    I use the export -v pad name.brd out.rpt, for export a file with old report format I read in skill this file and we have all information of the holes. ( slotx sloty or drill diameter , plated unplated etc...)

    Thanks you

  • This is the cadence solution. It's similar.

    It's an extract

     

    *Problem:

    I would like to extraxt the X and Y dimensions and the tolerance for my slot

    drills, what are the data fields used to extract this information?

    *Solution:

    The data fields for slot drills are:

    DRILL_HOLE_NAME slot major dimension

    DRILL_HOLE_NAME2 slot minor dimension

    DRILL_HOLE_POSTOL drill hole Positive tolerance

    DRILL_HOLE_NEGTOL drill hole Negative tolerance

    Save the text bellow as a file and you can use it in the Allegro report program

    to generate a report for slot drills:

    # ncdrill_slot.txt

    #

    COMPOSITE_PAD

    #

    # Slot hole types would have their major dimension in DRILL_HOLE_NAME

    # and their minor dimension in DRILL_HOLE_NAME2. CIRCLE_DRILL types

    # will simply have DRILL_HOLE_NAME2 set to the same value as in

    # DRILL_HOLE_NAME.

    # DRILL_FIGURE_ROTATION for slot holes will contain the rotation to be applied

    to the slot

    # hole, with the assumption of 0 degrees being the major dimension

    # of the slot hole along the X axis.

    #

    DRILL_HOLE_TYPE = CIRCLE_DRILL

    OR

    DRILL_HOLE_TYPE = OVAL_SLOT

    OR

    DRILL_HOLE_TYPE = RECTANGLE_SLOT

    #

    DRILL_HOLE_TYPE

    DRILL_HOLE_NAME

    DRILL_HOLE_NAME2

    DRILL_FIGURE_ROTATION

    DRILL_HOLE_PLATING

    DRILL_HOLE_POSTOL

    DRILL_HOLE_NEGTOL

    DRILL_HOLE_X

    DRILL_HOLE_Y

    So whatever became of this request? I don't see anything new in 16.2 (or 16.3 for that matter).
