What is Aperture Table
An aperture table is a comprehensive table or list that contains essential information about the apertures used in the manufacturing process. Apertures are indexed shapes or line-types utilized by a photo plotter to plot geometric patterns on film. They can also refer to small, thin, trapezoidal pieces of plastic that shape a light source for plotting light patterns on artwork film.
The aperture table serves as a reference for photo plotter operators and PCB designers. It provides details such as the index names, shape, usage (flash or draw), and dimensions of each aperture. This information enables operators and designers to select and configure the appropriate apertures for their specific needs. The aperture table is typically a component of the CAM (Computer-Aided Manufacturing) file used in the PCB industry, ensuring accurate and efficient manufacturing processes.
