Castellated pads

Without castellation service, done on purpose, on the typical Chinese PCB fab. [They seem to have ran out of ink on the silk screen too]

The through hole metalization is ripped apart at the time of the cut, so no electrical connection between the layers. The top and bottom metals are a bit shred and require a bit of filing to remove sharp corners. In short, quite unusable as castellation.
