What is the rule of thumb for pad size vs. size of the pads on the
Land Grid Array part (Land Grid Array is like a ball grid array but
with no balls...just pads). I guess this is also called planar mount.
The package is a micro-LGA with a 3 x 3 array of .020" pads. I am not
sure what to do with the pc board design. Are there design
guidelines?
Help would be appreciated.
