So I have been playing with this idea recently and I wonder if there are keyboard experts here who could weigh in.
What I would like to do is to make a Metal core PCB that contains the entire circuit for the keyboard but it also functions as the mounting plate. So essentially I'd solder two wires to the two pads to connect the keyboard. A cool advantage is that I could make a keyboard quite a bit thinner by virtue of saving the entire PCB stack.
One thing I would be worried about is routing of all the wires.
