Homebrew PCBs

I tried around with it most of the day.
The ink doesn't seem to resist fully and properly.

I even tried FeCl, but the stain in a bottle shows even more  
damage/under-etching than CuCl.
(BTW: many year old FeCl already mixed in a PET bottle is still good, and  
i discovered the vacuum sealed PE bags of FeCl powder/granules have let  
through enough water to wet it slightly. that stuff must be hygroscopic  
like crazy.)

I've started a wiki here which gives me lotsa easy-upload space for pics  
(200Mb)

I hope you have permisson to view as-is, let me know if not.

Basically the etchant etches through and i do not know why.

Anyway, i'd thought i throw that at you guys for ideas.

Volkan, is there a way to measure at which temperature and how long you  
cure?
