Hi,
The tracks were really small... and may be you let the etching too long time ?
By the way, how did you succeed in having such a beautiful transfer ?
I have spent hours this week end tying to toner transfer a pcb... unsuccessfully... Always some tracks missing...
And I tested 12 times...

I don't know what ratio to use. Should I dilute the H202 with water? I'm worried about the combination turning into boiling water. Also, are lined latex gloves, the kind you use for kitchen cleaning, sufficient gloves? Does it matter which you pour in first? I plan on doing this outside. I have a plastic container for both the etching and the remaining enchant.
