Provided you have wide spaces between traces, what is the thickest copper (internal/external foil/plating) commonly acceptable to your Fab houses?
We have a boardhouse here doing 300um = 0.3mm copper with traces about 0.5mm apart. The 300um copper approximates to 8 ounces I guess.
This is electrically built up in a normal galvanic process.
