Some format issues in METRIC are more difficult to reliably correct. Try exporting the drill file with the INCH units. Make sure any uploaded zip files include this file. Common Issues Missing Drill FileĪltium keeps the drill data in the project-name.TXT file. See our guide for limitations and DRC requirements of slots. SlotsĪltium’s native Slot callout is supported.
If the drill files do not appear correct, check out our Drill File CAM configuration page for settings that we know will work correctly. Drillsĭrill files should work without issues for most export options. This layer can also contain board cutouts.įor best results, place the outline by itself on the Keep Out, or on a Mechanical Layer (normally 1 or 2). This tells us where the fab should mill the edges of the board. We need a watertight board outline on its own layer with no extra text or measurements. See our Positive vs Negative Gerbers page for additional information. We recommend submitting planes with a Positive polarity. See Altium’s Gerber Setup for information on how to access this setting. When these footprints are added to copper layers, it can create gerbers that will be fabricated with shorts. 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.
