tip and craig,

The PCB industry is looking more at Ag as a finishing agent for the PCB... I have noticed that many end users are starting to request Ag on some of their deliveries to test it out. Visteon is one that comes to mind. Sn/Pb (Tin/Lead) finishes are fused either post plating or by way of dip process. This causes inconsistancy of finish (Puddling, dewetting, graininess...) where a plating finish is much more consistant, especially for finer features.
