Hi all,
I have a few sheets of 90 mil FR-4, (red imprint) that is double
sided.
I need to do a lot of 1 sided boards and instead of ordering one
sided, I think I'll just etch one side of these to use the boards.
Anyway, I mechanically etch boards so I need to remove the copper in
wholesale fashion and have no chemicals to do so.
To make matters worse, the boards are 10 x 18.
What is the simplest, lowest cost method to remove one side of the
copper ?
Also, I assume something like car or floor wax might make it easy to
add to the good side as a resist, but suggestions are welcome.
