Hello looking for a source of 2oz (70 micron) single sided copper clad PCB. I have looked at rs, farnell, and rapid and non of them list 70 micron thick copper PCB's. I am looking to finish the build on my power supply and it is this or wiring a bread board up and while I am much more familiar with bread board wiring I was hoping to learn a bit more in the process. So anyone know a source that I can get this from?
