That will not work on pcb's.
I would go for AP.

Hi. They are not pcb's - they are large copper blocks (hard to see it from the picture). I understand how to process the pcb's in AP. Thank you.

The all metal ones can be done in a Sulfuric cell.
The PCB's in AP, Nitric or even Cyanide if you can access it and follow protocols strictly.
