We been using the Sayaka SAM-CT23Q machine to depanel PCB, it was fine. But now, we have to depanel the Aluminum PCBs the current bits from IMPEC we are using are not strong enough (1.5x8.0 diamond downcut). Need to find much strong bit or bits des

Aluminum shreds were found inside the tooling hole after depaneling. We ruled out contamination because the tooling holes were covered during depaneling. Out of three holes, only 2 holes with positioning columns inside have aluminum shreds residue.

Can you post pictures here ? It should be quite straightforward to solve.

You cannot use diamond cut routers on aluminium. They will clog up in seconds.. You have to use "endmill" type. These are available from all PCB drill/mill supplier, nothing fancy. Depaneling - you mean cutting only tabs, not full perimeter ?

If you need to cut longer lengths and chip clogging / evacuation / edge finish is problem, then contact me privately, we have an unique solution for that.

I'm having trouble picturing your setup, but can you put kapton on the columns? Or heat shrink tubing?

Yes, just tabs not full perimeter. Can you please fill me in more detail since I am not too familiar to router bit types? I am looking for the right size bit that would be able to install to the Sayaka machine without much trouble just like diamond

You'll find a lot of guides for cutting aluminium on the internet but basically, try and use a bigger end mill if you can, keep it at the right speed (not slower). We cut 1.6mm aluminium with a 3mm end mill. Smaller end mills didn't evacuate the chip
