Plating on 3D printed ABS resins?
So, quick update on this:
After almost a year of trial and error, we finally figured out that a few rounds of Tollens' reagent (https://en.wikipedia.org/wiki/Tollens%27_reagent
) works like a charm... much more even finish than trying to electroplate copper, and IL (@ K-band) only marginally below metrology grade waveguide.
Paper will be submitted to IEEE CPMT soon; will keep everyone posted.
