I am toying with making a double sided board for a project that I have been working one for a while. While there has been a bit talk on the forum about through hole plating, there hasn't been much more
The chemical option seems as though its going to e time consuming and could easily go wrong and waste huge amount of board and seems to be used with milled PCBs. I currently only have photo resist and etching.
The next option as small strands of wire poked through with the components and soldered in place.
The last option is rivets. Not needed for vias as that can just be a piece of wire soldered in place
if the PCB was designed with slightly larger pads to accept the larger diameter rivets I can seen an issue but was wondering if anyone did infect have any experience with using them.
I thought if the rivets are pushed through the top and soldered there first, the can gently sanded back to nearly flush and the bottom side soldered in at the same time as the component. Or the back side flared with a round ended punch and gently hammered flat before soldering in place.

There are still some things to work, like how to get each side of the board lined up with exposing to UV light, and how best to etch both sides. but without through hole plating these are non issues really.
