Russ, We require 4 global fiducials on both sides (if components are on both sides) of the PWB as well as local fiducials, if the pin pitch is less than 25 mils. However, if two or more components are located completely within a 4 inch diameter only one local fiducial is required. E.A.

Does anyone REALLY use them? They consume a lot of real estate. Todays placement machines do an excellent job using only the global fidutials. Your responses are greatly appreciated !
