Having somehow never done one of these before I have a manufacturing question.
Given a single sided metal 'core' PCB of the sort one might use for LEDs or such (Actually I want to use it for some GAN Systems parts in an experimental power converter), is it possible to via thru to connect to the metal base plate to use it as a ground plane, or do I need to go to a two layer stack?
I can see that vias should be possible with a copper substrate, but does it work with aluminium?
Anyone have any experience with these, or in fact with the bottom cooled GAN Systems parts?
regards, Dan.
