Thread Summary

The user sought guidance on recommended and minimum pad sizes for the PCB footprint of the ADAU1860-1, particularly for using the minimum pad diameter. The support engineer provided a link to Analog Devices' BGA PCB design guidelines. The user found the ball size in the datasheet and confirmed the solution was sufficient.

Could you please provide information about the recommended and minimum pad sizes for the PCB footprint, and whether you suggest soldermask-defined or not?  

I'm in a battle with the PCB vendor over copper clearances and need to use the minimum possible pad diameter.

Thank you!
