The way of etching Double sided pcb?

2 1K

I want to etch my circuit on a double sided copper clad by myself. When I used iron paper got shrunk and ink spread all over and some connections didn't even go to the clad.Do you have any good way to get the circuit on double sided copper clad before etching.

I tend to cut off the wire for a small section, and solder around that, to try and make a good connection.

PCB manufacturers will tell you acceptable sizes for their process. They have a tolerance and a cost associated with different sizes, but unless you are making the next batch of Iphones you will probably just be given a cost per via, if even that.
