Hi,
There's a good reason that there is no double-sided phenolic out there (or
almost none maybe).
Phenolic can't be used with the common throughhole plating processes and
thus there is no point in having two sides of copper. (For PCB
manufacturers anyway).
Phenolic is only mass-used for cheap electronics where single-sided and
flimsy is ok.
Don't think you will have much luck.
Try etching first and use the CNC for drilling, you will like the results
better.
