Board Outline
 

The board outline defines the final shape of your board. For us to accurately create a route program from a board outline it has to be contiguous. This means a single loop defining the shape of the board with each line segment's endpoint perfectly aligning with the next segment's start point.

The smallest route bit we offer through our standard services measures 0.031" in diameter. If your board has a notch or indentation that is smaller than that we won't be able to accurately manufacture it.

We also require a minimum clearance of 0.020" between route paths. This includes both other portions of the board outline as well as any cutouts. Anything less than 0.020" runs a high risk of breaking or being cut during manufacturing.

If your order was placed on hold for not including a viable board outline there are a couple options going forward:

• A revised file set can be submitted including a board outline
• At your request we can generate a default rectangular outline with 0.020" of clearance from all included copper features

Other Items of Note:

• Palletization (tab route, V-score, etc.) is not offered through our limited inspection services (ValueProto & PCBExpress)
   
• Inside Chamfers are not recommended as they can result in over cut at the corners

• A minimum of 0.010" of clearance from the board edge is recommended for all copper features.  This will prevent cut traces and exposed copper at the board edge.
• Board dimensions are calculated from the center of the traces used to draw the board outline. When preparing your order for production we will generate the proper routing offset needed by our equipment for you.
