![]() ![]() Many footprints contain mechanical “courtyard” or “pick and place” data on these layers. The RUL file currently shows the older 13mil drill and 6mil ring Generating Manufacturing Filesįor accessing the various menus and output screens, see Altium’s Gerber Setup Disabling “ Mechanical Layers to Add to All Gerber Plots”Īltium tools have the option Mechanical Layers to Add to All Gerber Plots, which must have all layers unchecked. Known issues: Current minimum 2 layer specs are 10 mil drill hits, with 5 mil annular rings. If you have corrections or find errors, please email support. Use your judgment and always verify your designs meet our service specs to prevent design defects that could affect your boards. System Layers include Connections, Pad Holes, Via Holes, Visible Grid 1, and Visible Grid 2.Note, these files are not exhaustively validated or guaranteed by OSHPark, and may contain errors. Keep-Out Layer is used to define the area of printed circuit board.ĭrill guide and Drill drawing are used to do the drill drawing and drill holes position. It is used to place the text information like the components profile, the numbers of components. Silkscreen Layers include Top Overlay and Bottom Overlay. Solder Mask Layers and Solder Paste Layers are all negative. Solder Paste Layers include Top Paste and Bottom Paste, which have similar functions with Solder Mask Layers. Solder Mask Layers include Top Solder and Bottom Solder. Mechanical Layers are generally used to place indicative information about the PCB board printing and the assembly methods, such as circuit board physical dimension lines, dimension markings, data sheets, vias information, assembly instructions, and so on. Every Internal Planes Layer can have two or more power suppliers, such as +5V, +l5V, etc. The Internal Planes Layers are used to arrange the power and ground traces.These layers are negative. Signal Layers are used to mount components and traces. Signal Layers include Top Layer, Bottom Layer, Mid Layer1, Mid Layer2……. In general there are 7 working layers in printed circuit board: Signal Layers, Internal Planes, Mechanical Layers, Solder Mask Layers, Silkscreen Layers, System Layers and Others Layers. 7 Working Layers in Printed Circuit Board ![]()
