Re: Milling PCBs: Leaving behind "threads" of copper

Copper is notorious for its difficult machining characteristics. It has a tendency to be 'gummy' and 'catch the cutting tool. Careful selection of tool feed and speed go a long way to reduce those tendencies. A very sharp tool helps as well. As mentioned a brass brush to break off the tendrils wirks.
