I thought about it when searching a pair to use (using V 4.0.7), but I can’t exclude that I will need to design a PCB with SMD at both sides when as I understand adhesive should be used.
During that time I made one PCB with semi 2 side SMD assemble. My PCB is assembled at one side then break into two parts and put back together (3 (length 0) wires connect circuits at both sides).
I found that such solution allows me to make it smaller (important parameter in that case) then if I used 4 layers PCB. Assuming not using microvias the key advantage in my solution is that I can have via to GND at any place not colliding with anything at the other side.
I have added it just before asking my question when I can’t find how to delete it. Then I tried to close Pcb Editor and it asked me if I want to save changes - I didn’t wanted and I had not to use my backup. I am not designing yet. I am investigating V6 so there is no problem to get back to yesterday state.
It is not shown anywhere in the program - like it is not there, but why to have something what is extra and not needing in PCB file. When I will finish this PCB (few days) I will at once use it as a starting point for the next one and next one and they all will have something not needed.
Fortunately I don’t have it in.
