The critical importance of printed circuitry boards in the electronics industry is shown by the value of monolithic integrated circuits. The U.S. Bureau of Census (Product Code #36741) reports U.S. shipments for 1996 to be in excess of $8 billion. Printed circuit boards are essential to the electronics that control the operation of aircraft, automobile engines, electrical appliances, security systems, telecommunication networks, mobile telephones, television receivers, etc.

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. JoAT
