[PCB_FORUM] Re: bga balls

Sam,

 

Check out this article (a couple of years old!):

Of course, as always, it's a good idea to check with your assembly house.
They will have to deal with the geometries on your pcb.

Group: I have a data sheet that says the solderballs are .019 nominal. Is
there a rule of thumb for what pads size I should use?

TIA
