Can you isolate LV from ELV with stacked boards

[sensornewbie]

Hi,
I want to create an SELV circuit but am wondering if I can use a stacked PCB to create the required isolation and meet IEC/EN safety standards. Any thoughts?

Have the same doubt.

Did you found the solution yet? If yes, can you please help me out as well?
