To [log in to unmask] : We started using local fiducials on 132 pin gate arrays with mounting fingers on ,025 centerline spacing. We placed .100 dia solid pads on a diagonal within the footprint outline. Our in-house assembly people have now requested to incorporate local fiducials only on parts with mounting fingers located on .020 centerline spacing or less. Hope that helps.
