Etch your own flexible PCBs?
852 1 Oct 30.2019, 17:13:12

I would like to somehow DIY flexible PCBs using some fairly low tech/cheap method (my goal being antenna experimentation).  
Does anybody have any ideas how I might be able to do flexible PCBs on my own? (the main thing I want is nonplanar PCBs, in various shapes, and connect to them in a durable manner. 
Once in the right shape, they likely would not need to flex a lot.)
Is it possible to do toner transfer or something like that to make them?
Thank you!

You could try etching it as a normal copper PCB but using the really thin (0.25mm/0.01in) FR4.  It will flex a fair bit, but not quite as much as real flex PCB.
