cómo puedo ampliar el espacion entre las pistas y el plano de tierras?

@copilot cómo puedo ampliar el espacion entre las pistas y el plano de tierras?

Como consecuencia del flujo de trabajo automatizado en Flux, la herramienta automáticamente aplica la distancia de separación por defecto entre las pistas y el plano de tierra en el diseño del PCB. Pero puedes ajustar de manera manual esta separación en la pestaña de "Reglas de diseño" en el panel de la derecha. Aquí te indico cómo hacerlo:

Dirígete a la pestaña de "Reglas de diseño" en la barra lateral derecha.
Agrega una nueva regla seleccionando "Añadir" y escribe "separación" en el campo de búsqueda.
Haz clic en "separación entre canalizaciones y planos de tierra".
Ahora puedes especificar la distancia de separación que desees. Asegúrate de usar unidades de longitud correctas (por ejemplo, mm o mil).
Una vez que hayas especificado la separación, la herramienta volverá a calcular el plano de tierra para asegurarse de que las nuevas reglas de separación se cumplen en todo el diseño.

Asegúrate de revisar todo tu diseño para verificar que no se presenten conflictos o cruces indeseados entre las pistas y el plano de tierra después de haber hecho estos ajustes.

Por favor ten en cuenta que las reglas de diseño no se encuentran en los snippets proporcionados en este hilo, pero la explicación que te di se basa en las funcionalidades estándar de la mayoría de las herramientas CAD para electrónica.

how can i change the distance between the paths and the ground plane

@copilot how can i change the distance between the paths and the ground plane

The distance between the paths (or traces) and the ground plane, also known as clearance, can be adjusted in Flux. Clearance rules specify the minimum amount of space required between different objects in the PCB like traces, vias, pads etc.

Here is how you can change it:

Select the "Layout" object in the object tree on the left-hand side of the Flux interface.
In the "Layout rules" menu on the right, find the "Distance" field under the "Safety Rules" section.
Click the "Edit" button next to the "Distance" field. This will allow you to specify the values for various distances including trace to trace, trace to pad, pad to pad, and other combinations.
Under "From Ground Plane," specify the distance you need between the paths and the ground plane.

Please note that any distance entered should meet the requirement of your PCB manufacturer. If you have a specific manufacturer in mind, it would be a good idea to verify their capability and constraints before setting these values.

If I am assuming wrong that you are talking about Flux.ai, the CAD design tool for electronics, and you meant another tool, please correct me.

I cant find the safety rules section

I'm sorry for the confusion in my previous message. Please note that Flux uses a system of layout rules to control various parameters, including clearance.

Setting the clearance or distance between copper features (such as tracks and ground planes) typically involves setting layout rules in Flux. Unfortunately, the exact implementation might not exactly align with the guidance provided before, as different EDA tools have different ways of implementing these layout rules.

While I cannot provide specific steps due to the limitations in available information, you generally set up these rules on a per-object basis or based on selector-matching rules. To add a rule, select the object or open the layout rules menu, click on "Edit", then "Add", and search for the desired rule. Object-specific rules take precedence over selector-based rules in case of overlap[1].

If you are not able to see an option for setting the clearance between tracks and the ground plane, it might be possible that Flux handles this parameter automatically based on its advanced PCB layout algorithms.

If you still have trouble, you could reach out to Flux's support team for assistance. Their comprehensive knowledge would be best to walk you through their tool's specific processes.

change the clearance between the nets and the ground plane

@copilot change the clearance between the nets and the ground plane

To change the clearance (keep out distance) between the nets and the ground plane, you can leverage Flux's Keep Out rule.

Here is a step-by-step process:

Identify the nets for which you would like to change the clearance with the ground plane. Suppose these nets are Net1 and Net2.
In Flux, navigate to the Layout Rules sidebar on the right side of the PCB editor.
Create a new Keep Out Rule for each of these nets (Net1 and Net2). There are two different ways you can achieve this:
- Option 1: You can add an object-specific rule directly to the nets. Go to the Objects panel, select a net (Net1, for instance), and in the Object Specific Rules section, add a Keep Out rule. Here, you can specify your required clearance value in millimeters. Repeat the same process for Net2.
- Option 2: You can use Flux's selector-based rule which allows you to define rules that apply to multiple objects or nets at once. Create a new selector-based rule, and in the selector textbox, enter the net designator in the following format: #Net1 > trace, #Net2 > trace. In the Keep Out rule textbox, type fills(your_required_clearance_mm). Replace your_required_clearance_mm with your required clearance value.
After adding the rule, Flux will automatically adjust the clearance between the specified nets and the ground plane, based on the keep-out distance you provided.

Keep in mind that this will apply to all objects, which also includes traces. If you want to apply the keep-out distance only to the ground plane, you will need to specifically mention the objects and their respective keep-out values in the Keep Out rule as follows: 0.15mm vias(0.5mm) pad(2mm) fills(1.5mm). This example will keep all vias 0.5mm away, all pads 2mm away, and the ground plane 1.5mm away, while every other object type will stay away by 0.15mm (general keep-out distance)[1][2].

Please replace your_required_clearance_mm, 0.5mm, 2mm, and 1.5mm with the specific clearance values you would like for your specific design. As it is not mentioned, I am assuming typical values. You can correct these values as per your design needs.

Remember to review all the resultant clearances and check whether they are in accordance with your design requirements and manufacturing capacities.
