Hi all,
The best solution is to just use a 1000 psi burst disk. They are
standard parts for a number of manufacturers. If you are having an
operating pressure of 500-600, then the 1000 psi burst disk is still
only 1.67-2 times greater than the MOP maximum operating pressure and
1.5 times the MAOP.
Back to lurking,

We used one from a CO2 fire extinguisher.
It is a small screw in gizmo. Fire people did not know wat it was. They may call it a safety valve. Only used N2 on it so far.

In scope of pcb manufacture exist services that do laser cut
paste masks ( for smd soldering ...)
you can choose from a range of materials/thicknesses
and you can choose full cut or just variable depth surface "etching"
usually rather inexpensive.
Did anybody ever try that path for creating burst disks?
