PCB Design Process
Designing a printed circuit board (PCB) follows a systematic approach:
Schematic Capture: Begin by creating a schematic diagram that illustrates the electrical connections between components. This step requires selecting components from libraries and arranging them logically.
Component Placement on PCB: Once the schematic is completed, the next step is to place components onto the PCB layout. Correct placement is critical for both functionality and manufacturability.
Routing: Connect the components on the PCB layout using routing tools. This step involves defining traces that will carry electrical signals between components.
Design Rule Check (DRC): After routing, run a design rule check to identify any issues such as trace width violations or clearance problems.
- Generating Gerber Files: The final step involves exporting the design as Gerber files, which are used by manufacturers to fabricate the PCB.
