In this video I will use a Sephir double sided flex PCB. It is like pyralux but with a thiner transparent material. So you can make via easily but you cannot bend it too hard, neither heating too much. Well you will see that working with this is pretty easy and with very little training do a way better work that I’ve done here.
For info, in this video I am making a mini UV exposure box for a further product I will launch, which is presensitized Flexible PCB.
You can buy the Raw material here:
