Hi,
I am etching using HP gloss paper and an iron to do toner transfer. I have tried both FeCl3 and H2O2/HCl and in both cases the ground plane gets etched and pitted. I keep a close eye on the board and pull it into a water bath as soon as the traces are etched. Any tips? I have set my printer density as high as it goes and have also tried coloring in larger sections with sharpie after the toner transfer is complete just to add some protection. The transfer itself looks good, no peeling or bubbles.
Thanks for any tips you can offer.
