Homebrew PCBs

...and it will be pretty expensive i'll bet  :-)
To Stefan:
i came to the same conclusions like you independently :-)
i'm looking for a simple method to make the experiments repeatable to get an 
advantage over the exposure method if you have to do more than one board....
What i found out / think by myself until now is:
- keep out of the borders the printer uses mechanically to transport the 
paper...or end up like us repairing printers... :-)
- let the silicone coating dry out...i used the heatgun to speed up 
things...
- try lower ironing temperature (to let the toner melt, but not the 
silicone)
- the coating has to be sticky enough but not too glossy (how about not 
glossy at all?) to get the toner in the right position...
- make the coating repeatable even (i'm not sure, what kind of tool and 
method to use to get a fair result pasting the silicone to the paper)

that seem to be the most important points to me.
anything not mentioned about that???


Kind regards

Martin
