Can you put the mouse-bite breakaway on the edges of the boards next to the throw-away tabs only instead of board to board? Would be easier than say, having breakaway tabs on all four sides. 0.062" is common diameter for single-pass routing operations (as well as 0.093" diameter). Also depends on how the mouse-bite breakaway is designed (hole spacing. hole diameter, holes in line with board edge, holes offset from centerline of board edge, etc. Rgds, Roger M.

All, My fab house is recommending 0.062" spacing between the boards on a subpanel. I am using mouse-bite or rat-bite. As there are 5 boards per subpanel, I would like to get opinion on the recommended spacing between the boards and NOT between the board and throw away tabs. Here that hangover needed to removed from both boards and if it's only 0.062" wide then I believe it will be a bit little difficult to remove from the second board once removed from the first board. ________________________ Board #1 ________________________ this spacing ________________________ Board #2 ________________________ and more.... Any suggestion will be highly appreciated.
