I thought they printed to a plastic substrate.. There is conductive glue now. Solder is not here to stay, necessarily. > > 2) How low (ohms/unit of length) is low resistance? How many of those traces would have resistors in them anyways? Maybe trace width and length becomes the new resistor. Having a measurable resistance could be an advantage. I just felt like climbing out of the box today. When folks can print circuit boards and and glue down parts, it changes the dynamic of big guy vs. little guy.
