"Recommendations and comments

When castellated features are required, it is best to use the following general rules when at all possible:

• Use the largest hole size possible
• Use the largest Outerlayer pad possible, both top and bottom sides
• If possible, place Innerlayer pads to anchor the hole barrel. This will also help reduce burring during the castellation process.
• If the castellation is not used for a mechanical connection (i.e. insertion of a connector device), allow additional dimensional tolerance for the castellation opening if possible."
