I have reprinted a recent posting from Conductor Analysis Technologies of Albuquerque, New Mexico. They are in the business of analyzing test boards from various board fabricators to determine capability. One of the criteria from their analysis is microvias, and I think they can infer plating uniformity from conductor thickness uniformity across a panel. They may have Motorola available information already - I do not know if Motorola has asked them to audit various board shops already. The IPC-PCQR2 Committee also mentioned below is in the process of standardizing test vehicles for capability of board fabrication shops around the world. That committee has data on 15 shops so far, and is on the way to 30 data points by the time of IPC Expo at the end of March. Plating, and especially microvia plating, is part of the capability vehicle. Suggest you contact CAT about capabilities to qualify the plating at your fabricators.
