going against dsbga land pattern recommendation

Hi,

In order to conform to PCB design rules I would like to go against dsbga land pattern recommendations.

I'm using the bq27532-G1 and would like to route 0.09mm traces with 0.09mm clearance in between. This means the pad diameter should be no larger than 230um.

The recommended pad diameter according to AN-1112 is 265um +-20.

230um is still 15um smaller than the minimal requirement of 245um.

looking at Maxim's MAX14676 land pattern recommendations I see that they specify 220um pad.

How bad would it be if I would use 230um for the bq27532 then? Anybody got any experience with this?

Thanks!

Diederik
