Abstract:
1. A printer configured to print at least directly on a copper-clad substrate to facilitate inexpensively producing a printed circuit board, comprising: an adjustable feeding mechanism for feeding at least a copper-clad substrate into the printer; a printing mechanism, proximate to the adjustable feeding mechanism; and a computing device associated with the printer which stores a library of inverse circuit images; and one or more of the inverse circuit images are printed by the printing mechanism on the copper-clad substrate, wherein the inverse circuit image is allowed to dry, the copper-clad substrate is immersed in a tinning solution to adhere a resist mask to an exposed, uninked copper to form a tinned circuit image, and the copper-clad substrate is etched to remove copper that forms the inverse circuit image.
