[PCB_FORUM] Re: Package symbol for odd part

Hi Eileen,

Here is how I would do it:

-          Create 2 round shapes for 2 ends of the oblong.
-          Add a rectangle shape between the 2 rounds to fill in the middle.
-          Use Shape/Merge and turn those 3 shapes into 1 oblong shape.
-          Same technique, use 2 circle and 1 rectangle voids to create the 
oblong void.
-          Use rectangle void at one end to create the little trim.
-          For holes, use Add Pin and select copy mode POLAR for the ends, 
angle set at 36 deg.

For anti pad, just create an oblong shape and use it in your padstack. For 
thermal, I will the add shape with combination of line & arc to create the 
broken shape.

Have fun!

Subject: [PCB_FORUM] Package symbol for odd part

Hi,

Any one happens to have package symbol for Allegro ACS758 to share?

If not, kindly advice how to create the odd shape with the small drill holes, 
also the thermal and anti-pad.

I'm using Allegro 16.01

Thanks in advance,

Regards,
Em
