PCB verifications refer to the process of checking and confirming whether the PCB design is accurate and in accordance with the desired specifications and standards. It is a crucial part of the PCB production process to ensure that the final printed circuit board is error-free and functions as expected.
Design Rule Check (DRC)
This is an automated process where design software checks the PCB design to ensure it complies with specific design rules and constraints. DRC verifies parameters such as trace spacing, trace width, component clearance, etc.
Design for Manufacturability (DFM) Analysis
DFM analyses identify potential production-related issues in the PCB design, such as traces that are too narrow, insufficient clearance, areas difficult for soldering, etc. This helps optimize the design and enhance the quality and reliability of the final PCB.
Electrical Verification
This process involves an electrical check of the PCB design to ensure it aligns with the original netlist or circuit diagram. It identifies any shorts, missing connections, or other electrical faults that could impact the desired functionality.
Netlist Verification
Netlist verification compares the generated netlist with the original netlist used to create the PCB design. This ensures that all connections are accurate and consistent between the design software and the production.
Visual Verification
Visual inspection of the PCB design ensures that all components, traces, paths, and symbols are correctly placed and aligned with the desired layout.
