Hey guys,

I was wondering if anyone has tips for etching dual layer pcbs (mostly how to get both sides well aligned)

Thanks

My first try was aligning the two pieces of paper with the layout against the light and taping the edges just far away enough so that I could slip the PCB inside. It worked nicely.

Here you already see the connections from one side to the other.
Since it was also my first one, I kept changing sides around the main components to accommodate all the parts as close as possible. But, as you can see, they align pretty well for a small board.

This one is just for reference. Lots of pretty small smd stuff there.
