Yes, we do. We have a couple of densely populated boards with a lot of polarized capacitors. We made a template out of .010" thick copper. An artwork was generated for the component locations and the copper was etched like fabricating a stencil. The polarity was then marked with ink on the template. This works rather well. Once you generate the artwork your stencil supplier could etch the material. No frame is needed.

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.
