I noticed the milling machine had been used. Will it be available for everyone to use? I would like to have a go at making PCBs. I can buy and donate some materials and bits. Is there anyone who could help me out.? I have designed multi-layer and two layer PCBs in the past. I can have a go at a 1 layer design. Will probably be a small stamp sized board to start with. I can produce gerbers for a copper layer and routing and a drill file for any through hole components and mounting points.
I know for a milling machine its best to fill the copper to reduce the amount that needs to be removed. I usually add the printing to the copper layer. There is no need for a solder mask to start with. (Use tarnished copper and polish where you want to solder usually does it.)
We could try two layer but this adds the complication of flipping and aligning the PCB. Also we may have to get some vias. The prototyper I have used before used rivets as vias that were hand fitted. If there are no vias in the design then sometimes you can get away with soldering both sides of a through whole component.
Any advice of file formats, parts or tools needed, or anything else is very welcome. Any donations of scraps for testing very welcome.
