From circuit diagram to PCB layout (5/5) - 4-layer layout, fiducial marks, spacing, component lib...
In the fifth and final part of this series, I'll cover creating a 4-layer layout, as well as registration marks, test points, design rules (such as spacing and pad sizes), and component libraries.
``` 0:00 Conversion, adding layers in KiCad
1:02 When are 4 or more layers necessary, PCB cross-section and what lies on the layers
2:39 Removing GND pads (top and bottom)
2:55 Creating inner layers and assigning net names
4:00 Open connections, moving and rerouting DK to GND/+12V, removing blocking pads
6:35 Further modifications, removing the 12V connections (previously: bottom side)
8:30 Inner 12V between through-hole components
9:33 View: Top and bottom individually
9:50 View: Inner layers
10:45 Removing solder mask
11:08 Changing text, version
11:24 Firing marks and test points
16:36 Design rules: Spacing and pad sizes
22:17 Example SOT23 and BD140
25:17 Distances to the PCB edge
27:30 Component Libraries
34:20 Summary
