ABL Circuits PCB Manufacture Photo Plots

Once the panels are laminated, which is done in the yellow room because the film is UV sensitive, the photo plots which represent the component side and the track side, both have precision tooling holes punched in the field for locating on to the panel. These are positioned on a tooling pin and clamped down and the whole panel is put into the exposure unit which exposes the panel to ultraviolet light.
