For what it's worth; We ran across a similar situation about 2 yrs. ago. The settings of the gerber data generation from our CAD tool was only 3 decimal places. We used a fine pitch connector and everything looked fine on our end, but the CAM station told a different story. Almost every trace was shorting. We went to 4 decimal places and it looked much better.
