PCB board preperation | 6 November, 2014

As part of the process of assembly, we have to scuff the surface of our board around the border about a half inch in from the edge before application of an adhesive. We have been doing this by hand with 60 grit sandpaper, we are looking for a way to do this mechanically but our attempt with wire wheels or sanding drums result in gouging into the surface. Does anyone have any good suggestions?

Just wondering why you need to scuff the surface at all, as a decent glue should take to the PCB material anyway.

However, it may be a customer requirement, so you have to do it.

Have you thought about getting the PCB's made with a rough surface where it is needed? They may have the ability to provide an area of roughness that is suitable for your needs.
