3. Add components from the library or create custom components
4. Connect components using wires or buses
5. Define component properties, such as values and footprints

Component Placement

Once the schematic design is complete, the next step is to place the components on the PCB layout. PCB Visualizer provides tools for manual and automatic component placement.

Manual Component Placement

To manually place components on the PCB layout:

1. Switch to the PCB layout view
2. Select the component from the schematic or the component list
3. Place the component on the desired location on the PCB
4. Rotate and adjust the component as needed

Automatic Component Placement

PCB Visualizer also offers automatic component placement functionality:

1. Define placement constraints, such as component grouping and keep-out areas
2. Run the automatic placement tool
3. Review and adjust the placement results if necessary

Routing

After component placement, the next step is to route the connections between the components. PCB Visualizer provides both manual and automatic routing options.

Manual Routing

To manually route connections:

1. Select the desired routing layer
2. Choose the appropriate routing width
3. Start routing from a component pin or a via
4. Continue routing until reaching the target pin or via
5. Add vias as needed to change layers

Automatic Routing

PCB Visualizer’s automatic routing feature can save time and effort:

1. Define routing constraints, such as via styles and routing preferences
2. Select the connections to be routed
3. Run the automatic router
4. Review and adjust the routing results if necessary

Design Rule Checking

Design Rule Checking (DRC) is an essential step in the PCB design process to ensure that the design meets the required manufacturing and electrical constraints. PCB Visualizer includes a comprehensive DRC tool.

Running Design Rule Checks

To run design rule checks in PCB Visualizer:

1. Define the design rules, such as minimum clearances and trace widths
2. Select the desired rule set
3. Run the DRC tool
4. Review the DRC results and address any violations

3D Visualization

PCB Visualizer provides a powerful 3D visualization feature that allows you to view your PCB design in a realistic, three-dimensional representation.

Viewing Your Design in 3D

To view your PCB design in 3D:

1. Switch to the 3D view
2. Adjust the camera position and orientation
3. Apply realistic materials and textures to the components and PCB
4. Inspect the design for potential issues, such as component clearance and mechanical fit

Manufacturing File Generation

Once your PCB design is complete and has passed the necessary design rule checks, you can generate the manufacturing files required for production.

Generating Gerber Files

To generate Gerber files in PCB Visualizer:

1. Select the desired Gerber file format and settings
2. Choose the layers to be included in the output
3. Define the aperture settings
4. Generate the Gerber files
5. Review the generated files for accuracy
