Morning everyone, I have a question on IPC-4553, specifically, section 3.1 "Visual", and specifically regarding staining of immersion silver. The text states "The coverage shall be complete and the finish shall be uniform on the surface to be plated (see Figures 3-1 through 3-5 for properties visually identified with IAg plated surfaces)" Figure 3-1 shows 'Example of Uniform Plating", with no staining. Figures 3-2 through 3-5 show staining. Is this to imply (without text to support) that any staining of immersion silver is determined to be non-uniform and therefore a defect? Thanks. ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
