Yes, both foil templates from a stencil vendor and various mylar templates. Antistatic material is available or you can spray standard materials. Thick foils (12 or 15 mil, usually require chem etch) are more durable. This type of inspection is most effective if the number of locations is limited as much as possible. The other extreme is a tool with a hole the size of the board and instructions to "make sure everything is OK".

TechNet, Has anyone tried to use templates or overlays at the end of a machine process or the end of a progressive line as a quick check for polarity or component orientations? If so what type of materials did you make your overlays from? Were they conductive for ESD? Where did you have your templates made? Can a board house make these from Gerber data? Stencil shop? I would appreciate your comments. Thanks. J.
