Create BGA Footprint With Offset/Staggered Pins

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am trying to use the LE Pro to create a footprint for a part using an WLCSP-64 package.  

This has alternating columns of pins offset/staggered.  

What do I need to create this footprint and STEP model with the LE Pro?

	You can easily build this part in FP Designer in less than 3 minutes, once you know how to do it. Here are 2 articles on how to create Staggered Pin BGAs in V25.03 Footprint Expert. https://www.pcblibraries.com/forum/staggered-pin-bgas_topic3465.html https://www.pcblibraries.com/forum/automate-footprint-creation-with-text-files_topic3464.html The 3D STEP model will be a simple extruded block that will match your package dimensions and Polarity Marking selection.

	Thanks. Although that works it is quicker/easier to create the footprint with my own workflow in my CAD package than using the FP designer. I was trying to use the "Create new Surface Mount" tool to get an IPC7351 compliant footprint and reasonable STEP model. It does everything needed except the ability to set any offset for staggered rows/columns.
