For Quickturn, the board can be any shape but the outline is limited by the size of the router bit. The router bit is .093" which requires a minimum notch of .100" The router must also be able to follow one continuous line without breaks.
Please note that board outlines for Quickturn will be rejected if they contain broken lines, overlapping lines, improperly drawn arcs and/or notches that can't accommodate our .093" router bit. We reserve the right to change the board shape to a default 0.0 (square or rectangle) snapped to the existing board outline"if" the board shape is difficult or not a single continuous line. Notches which are smaller than .100" are removed from the outline. To prevent this from occurring (if your board outline is rejected), you can specify on your order form to "hold the order for outline redraw." The order would then go on hold, a notice will be sent to you for a new outline file. This process can delay the final ship date of your order.
