BGA Pad Size Deep Dive | Component Creation

Zach explores how to size a BGA pad in this video, which is in response to a fantastic viewer question. What information can PCB Designers find in the datasheet? What about IPC standards? And what do you need to know in order to select the correct pad size? Learn here.

Great video, here are some self-proclaimed IPC compliant land pattern generators:
- PCB libraries Footprint Expert: free and recommended by several PCB design experts.
- Snapeda: they have an online tool for generating IPC compliant land patterns.
- Samacsys: the cool thing about this tool is that it also generates simplified 3D models of the components in addition to the land pattern.
I said self-proclaimed because I didn't verify these tools against the IPC standard. I hope this helps.

Xilinx does provide recommendations for pad dimensions in a document which also describes packages (for 7 series FPGAs it's UG475).

Hi Asmi, I'm sure they do, and of course they put it in a separate document on packages and not the datasheet! I've seen some other BGA components where they provide a pad recommendation. Just to verify, before making this video I looked and found some datasheets from Xilinx component where there was no recommended land pattern.

Hi Zach, the dog-bone is it created manually by placing the via in the center of the bga pads and symple routing via-pad or are there already predefined ones?. Great video.

[@Zachariah-Peterson]

The dog bone fanout is not created manually. You can do it manually if you want to, but there is a feature in AD that will do this for you. Take a look at this video to see how to do this: th-cam.com/video/6QfWWTE4PI0/w-d-xo.html
