Footprint for UBGA 324 pin package

Hi Rod,

Based on my understanding, Altera will provide the OrCAD symbol in .OLB. The OrCAD symbol can be downloaded from Table 2 of the following link:

Thank you

The Orcad .olb files are the schematic symbol. I need the recommended PCB footprint.

Following that same link there is a download link for the file "device_family_footprints.zip" but it does NOT contain the UBGA 324 package. I don't actually want a .dra file anyway as the footprints we use must be made with our own padstacks. All I really need is a drawing. This information is usually included in a datasheet but I can't find it in this case

Hi,

From my understand, Altera no longer update the PCB Footprint Libraries for Cadence Allegro PCB Tools. We will only provide the OrCAD symbol in .OLB.

The PCB footprint libraries which can be downloaded from Table 1 is applicable for the mature devices.

Like I said before, I don't want the actual allegro file. I want a drawing that specifies what the pattern is.

This drawing must exist. I don't understand why it is so hard to find.

Hi,

You can find the package drawing in the link given below

For this particular package they haven't given .dra files but you can create the footprint based the given package details.

Best regards,
