Power net portal is a special schematic object used to define a power or ground net. Power ports allow you to conveniently indicate a power net at any location in the design. Power nets of the same designator automatically connect throughout your design #portal #power
A generic fixed inductor for rapid developing circuit topology. *You can now change the footprint and 3D model at the top level anytime you want. This is the power of #generics
Adding a via in Flux can be accomplished in two ways:
When you're in routing mode, routing a trace between two points, you can add a via by selecting the target layer. Right-click and select the layer where you want to continue routing. Flux will automatically place a via at that location and continue the routing in the new layer.
Alternatively, with the "Layout" object selected in the main design window, you can add a via by right-clicking in the desired location, go to "Add", and then select "Via".
A via is used to connect traces from one layer to another. If your components are on both the top and bottom layers of the PCB, you might need to use vias to connect the traces between these layers.
To make vias connect to the ground (GND), you'd need to add them to the ground net in the Flux software. Here is a step-by-step guide on how to do it:
First, find the "GND" net in the "Nets" section on your Objects panel (usually found under the "Layout" section).
Click on the "GND" net to select it. This action opens up the "object-specific rules" menu to the right.
Now, add a "Connected Layers" rule. This rule enables or disables the connectivity of the particular net (in this case, GND) to the copper layer.
In the "Connected Layers" rule, select all the layers where you want the GND to be connected.
When you place a via while routing the GND net, it will now connect to the GND fill on the layers you selected.
Please note that all the copper fills (including ground and power) are hidden by default for aesthetic purposes. To see them, you can toggle the visibility on under the "Layers" section of the PCB editor. Look for a teardrop-like icon next to the layer visibility tool. Pressing this will enable you to toggle the visibility of your copper fills.
Remember to apply 'Stitching Vias' to your ground fill. This helps maintain a low impedance path for return currents and reduces noise throughout the board. The "Fill Stitching Density" and "Fill Stitching Offset" rules under the GND specific rules will allow you to configure the stitching vias.
To create a region without any copper (also known as a copper cutout or copper-free region) in Flux, you have two main options:
Option 1: Single-Layer Cutout
If you want to create a copper cutout around a pre-existing element, you can add a "Keep Out" rule. This will repel the auto-generated copper planes away from the part at the specified distance. Here's how you can achieve that:
Select the object around which you want to create a copper fill (such as an SMA connect for example).
Navigate to the layout rules on the right and add a "Keep Out" rule, customizing it based on your needs (units, x-spacing vs y-spacing, etc.).
Option 2: Multilayer Cutout
This second option is more of a workaround for creating a cutout on all layers:
Add a small pad onto the canvas. To do this, select the Layout Object in the object tree, right-click in the canvas, and select Add -> Pad.
Edit the size of the pad by adding a size rule.
Follow the same steps specified in option 1, but with the keep out rule applied to the pad.
Specify what layer(s) you want the cutout to be located on by modifying the Layer property on the pad
This allows you to move the pad around dynamically and automatically regenerate copper cutouts depending on the keep out rules specified.
During the gerber export, the pad may show, but this can be etched away by the manufacturer[1].
Hey, I’m Copilot, your AI design assistant. I can help you brainstorm ideas, debug problems, research components, and even make wiring connections for you. Ask me questions like:
@copilot I'm designing a PCB for a medical device that measures heart rate and temperature. Can you give me the list of components I will need?
@copilot How would I connect these parts to make the LED flash at 1kHz?
@copilot can you choose 4 digital pins on the ATMega328P-AU that I have here to use as GPIO given that I am already using some pins for reset, the external clock, UART, and I2C.
Chat with me by tagging @copilot on comments or in the chat.
