Placing the padstacks as per the pin location entered in Text file

Hi All,

I have to create a footprint for a part for which the datasheet is given limited details. I have the X and Y co-ordinates for all the pads given in the datasheet. So I do have to place all the pads one by one taking X, Y co-ordinate from the datasheet. It consumes most of my time if the pin count is more than 50.

So, is it possible to import any text file to allegro in which all the pin location is provided to place all the pins in one shot? And how to map the padstack in this case?

Hope someone can help me out.

Thanks & Regards

Hi,
I have one more continues task to create some shapes in Footprint. The reference I have is the component size. that is ASSEMBLY_TOP.
And I have to add 3 shapes to this footprint.
1. Package Geometry/Display Top (Expand ASSEMBLY_TOP to 375 um)
2. Package Geometry/DFA_Bound top (Expand ASSEMBLY_TOP to 75 um)
3. Package Geometry/Place bound top (Same as ASSEMBLY_TOP)
I have tried this recording the Z-Copy option. Unfortunately it is not working since it is getting stuck during Pick command.

Can anyone help me out?

Hi

Instead of using scripts I would recommend using the builtin skill commands.

I assume you have the dbid of the assembly_top and hence the polygon forming this outline, in that case simply use axlPolyExpand to do the operation.

Best regards
Ole
