How to start PCB rooting?

The PCB rooting process is essential to ensure an efficient and functional printed circuit board design. Before starting, it is crucial to have the components organized and to be clear about the circuit design. Here are some essential steps:

• Define rooting rules: Access the configuration menu under "design rules", where you can set minimum limits for track width, diameter and via bore. This is essential to avoid errors during the design process.

• Start component rooting: It is recommended to start the rooting following the order in which the components were placed in the schematic. Prioritize the power and communications part.

What are the recommendations for track widths?

Different circuits require different track widths. Here are some suggestions for choosing appropriately:

• Data signals and simple connections: use a 0.254 mm track width, ideal for less critical connections such as between two resistors.

• Power, ground or power connections: Try to use a 0.508 mm width, as these lines need to withstand more current.

How to connect components between layers?

Connecting components between different layers on a PCB can be a challenge. Here is an effective way to do it:

• Using 'vias': With the insert vias option (usually using the 'v' key), you can traverse the PCB and connect tracks between different layers.

When following this method, be sure to be guided by your schematic and confirm it in the proper order of the signals.

How to handle layers in the rooting process?

Correctly choosing the layer to trace a track is crucial to the success of PCB fabrication:

1. Select the appropriate layer: From the right menu. Switch layers if necessary to avoid design bottlenecks.

2. Change the track width: If you find a pin that is too small, it will automatically be necessary to reduce the track width.

These steps help to maintain consistency and clarity in the design, crucial for a well-structured track.

How to avoid routing errors?

Errors during routing are common, but here are some tips to minimize them:

• Esc to undo: If you make a mistake, you can use the Escape key to undo the last step.

• Debug Wizard: Use software tools such as KiCAD's debug wizard, which can identify and help you fix errors.

It is critical to take time to plan and review each step to avoid inconveniences later in the PCB development process. Location and order in the design, after all, makes it easier and saves time in rooting.
