TechNet - One of our customers is looking for an ink or masking material to obliterate or hide surface mount IC markings for security purposes. Currently, the IC markings are mechanically removed, but this is a slow process. Screening or tamping an opaque ink seems like the best idea, but does anyone know who supplies an ink for this purpose? Any other ideas will be appreciated.
