content: Seems like a couple of PSU modules mounted on a board. Clever but what I don't like is that the modules seems to be held in place by solder joints instead of some screws. It is likely to fall apart!

content: This has to be a joke right?-Those switching modules are NOT CE compliant at all unless you have tested them in your application. Search for a the test report and carefully inspect how they have been tested. Perhaps they are only CE compliant when a load has been connected trough very short wires. I know from experience that some of those power supplies fail radiated and conducted emission tests (and not a little bit) when they are being build into a complete system.-How about creepage and clearance on your self etched PCB?-How about creepage and clearance between the individual power supplies? That doesn't look right to me.-Oscilloscope power supplies are not only about output ripple. How about high frequency output noise?
