Now to panelize this small irregular PCB

Q:

Hello, we have been struggling to properly panalize this design to pass JLCPCB requirements. The final finished product we need is shaped like this:

Ideally the panel would create parts that are clean-break so there is no manual rework to cleanup burrs from mouse bites, but maybe that is not possible and we will have to do some clean up on the separated boards. We attempted to create a panel with a board outline like:

But when panelized it failed audit because the slot region is too close to the board edge in 3 places:

The suggestion from the audit is to increase the spacing between the slotted area and the board edge to at least 3mm. But that will make it very hard to break off to get the final shape.

I think slotted regions can be very close (0.5mm) so maybe we could make the shape completely from slotted regions and just have a larger rectangular board outline. But would that cause the same weakness as having the slotted regions close to the board edge?

Any suggestions on how to do this? Thanks!

A:

You could consider panel with v-cut since your board edge is flat. But it is still recommended to reduce the internal slot, to decrease the risk of board breaking. If the part on the left of the internal slot is the actual PCB you need, then we do not have better advice for panel format.
