Are you willing to spend the time it takes to create that footprint or spend the extra $0.50? The answer depends on the volume and complexity of the footprint. Company B sells virtually the same part priced at $5.50 but with a footprint. Why would they spend their time doing this? Imagine Company A sells a connector for $5.00, but no footprint is provided. ![]() Companies now realize this pain point and offer designers free, well-designed PCB footprints. It’s tedious, time-consuming, and doesn’t result in much except, well, a footprint. Designing footprints is a job most people hate. Under Hole information, change Round to Slot.One of the biggest hurdles individuals and startups face with creating new PCB designs is footprint creation. Here’s how:ġ.Double-click on the pad to show Properties.Ģ. Q: I’d still feel more comfortable having an official slotted hole in my design, is that possible?Ī: To alleviate any aesthetic (3D view) or communication concerns with your PCB manufacturer, simply modify the size and shape of the round hole generated by SnapEDA to be a slot. Note: Since the slotted holes will not be shown in SlotHoles.txt produced by Altium when you generate the gerber files, make sure to mention the slots on Mechanical Layer 1 to your PCB manufacturer for clarity. When manufacturing your design, ensure that you have sent the gerber files for Mechanical Layer 1 to your PCB manufacturer. Q: Will this cause issues with PCB manufacturing?Ī: No, the cutout placed on this layer will override the round hole shown on the footprint, generating the desired slot. As a result, all slotted holes are placed on Mechanical Layer 1 as per Step 4 of our Import Guide. Q: Why does the slotted hole in the footprint I downloaded appear round?Ī: Due to a limitation of the Altium file format supported on SnapEDA, we can only export round holes. The article below is now outdated, but if you have the former. Update: SnapEDA now supports native slotted holes in Altium! Learn more here. ![]()
