Hi. At the PCB fab sell-out I'v been visiting the last couple of weeks, they had a single side, 210 my copper (=3D 6 oz), on a 3.00 mm fiberglas (FR4) base. That would be excelent to build high current PCB on. You could probably mount transformers and all directly on the PCB. I'm going there Monday morning, and I'll think that I'll check if I could get a few of these. (They also had a *double* side, 210my copper laminate, but that was built on a 0.20 mm base. I'm not sure that's usable. And there are 70my (2oz) laminates in different sizes including 0.20mm, 0.30mm, 0.45mm and 0,50mm. All double side, FR4 class.
