Is it possible to build/modify a plotter and reliably expose a PCB directly?
I know that plotters are used to expose photo-masks for production PCB runs, are they more sensitive to exposure then the PCBs?
I would consider building a plotter and use a UV LED to expose the PCB.
Its for hobby work, so if it takes a while to expose the board, its not such a big deal
Anyone have any thoughts on this?
