Understanding OrCAD Classes and Subclasses for PCB Land Patterns / Footprints

The parts of a Footprint or Land Pattern can get really confusing, because they hold so many elements. In this video, I will clear up that confusion by showing you which layers in OrCAD apply to the ideal IPC-compliant footprint and why they’re used. In-depth video for footprints in general:    • Understanding PCB Footprints - The Id...   Someone asked me about the classes and subclasses that OrCAD PCB Editor uses, especially regarding footprints. This video is best suited as a PCB tutorial for beginners as it gives much deeper insight into the PCB footprint and how it's created. 00:00 Introduction 01:06 Understanding Layers of a PCB Land Pattern 02:34 Understanding Classes and Subclasses in OrCAD 04:54 Silkscreen Pin 1 Polarity Marker 05:30 Assembly Pin 1 Polarity Marker 06:18 Pin / Land 06:50 Paste Mask 08:00 Center of Gravity Origin 08:33 Solder Mask 10:15 Courtyard 11:14 Assembly Outline 12:00 Silkscreen Outline 13:16 Reference Designator Silkscreen 13:58 Reference Designator Assembly 14:23 Land-to-Land Gap 14:48 Thermal to Land Gap 15:09 Silk to Land Gap 16:10 Thermal Pad 16:44 Thermal Paste Reduction 18:56 Conclusion As long as you include everything we talked about in this video within your PCB footprint, you’ll always make reliable land patterns for your projects and clients. And as an added benefit, you'll have fewer problems with your finished printed circuit board designs. For more information check out my video where I explain the details of why we have these different parts of a PCB footprint and how important they are to manufacturing high quality printed circuit boards with fewer issues for you and your manufacturer.    • Understanding PCB Footprints - The Id...
