Datum Dynamics has been manufacturing Inspection Templates for a number of years, which overcome your problem. These are designed from the Gerber silk screen and solder mask layers. Made from 1.6mm thick FR4/G10 the templates drop over the populated board and can be engraved with suitable text. FR4/G10 is much more durable that a laser plot onto film, and does not damage components, as would a laser cut stainless foil. If you require more information, please email me or phone (401) 683 5300.
