  • A panel is a pcb on some what 60 cm * 60 cm that contains 1 - N smaller boards who is the actually customer pcb.

    Not shure but no breakage when depaneling, could be the capability to avoid tracks breaking, when you remove a single board from the panel.

    Multi-ups and array. could be that the manufactor have a system that carries several panels. When depaneling pcb's from all panels at one task, demand very precise setup of the panels to avoid cutting into a pcb on one of the panels.


    But it would be much more easy to reply on, if the complete text was precent.
