B&W image of a hand placing a ceramic plate into a machine.Includes caption: "In one method of making a printed electronic circuit at the National Bureau of Standards the prepared screen, containing the circuit pattern, is positioned on the ceramic base plate. The wiring diagram and inductors are printed on the plate by forcing silver through the stencil with a rubber squeegee. Here, the printed conductors consisting of silver oxide paint are shown just after the stencil screen is raised from the ceramic plate. The resistors are applied in the same manner except that their characteristic values are changed by varying their length, width, thickness and the composition of the graphite ink. (13.1) Photo 1099"
