I'm finishing up a couple of projects, about to start another, so it's time to start thinking about the next one in queue... Printed circuit board fabrication.
I've never made any PCB's but I'm hearing at least a little interest from fellow members. I'd first like to gauge how much interest there is in the process and having a dedicated circuit board station at the HF. There's a few methods, but I'd like to keep it scalable whilst keeping it cheap and providing a learning experience for newcomers to circuits. Photosensitive boards are simple but are expensive in the long-run. Screen print and etch is cheaper if you're making a lot of boards and has other uses for TCM (shirts, stencils, labelling pcb's, etc). The cheapest is toner transfer from magazine pages using an iron, but the brother laser printer in the shop office is known to have some issues. That's part A.
Part B is SMD soldering. I've got an SMD rework station that I've been meaning to bring in, but I'd also like to use the infrared oven technique using a toaster oven and griddle I've bought new for this project. It would need a PID controller that could easily be done on an (ahhhhh!) Arduino.
A small fridge would also come in handy to preserve the chemicals needed in part A.
What do you think? Can the HF spare a few square feet of space somewhere? Hopefully not the back bathroom... Would you like to partake in this endeavor? Does the HF have any qualms about housing muriatic acid, ferric chloride, sodium hydroxide, or photo development solution? An area with water supply and drain and could be a semi-darkroom would be best.
