What is PCB Reverse Engineering?
PCB reverse engineering is the process of examining an existing printed circuit board to understand its design, components, and functionality. This process involves several steps, including:
- Visual inspection: Examining the PCB with the naked eye or using a microscope to identify components, traces, and other features.
- Schematic capture: Creating a schematic diagram of the PCB based on the visual inspection and other analysis techniques.
- Bill of Materials (BOM) creation: Identifying and listing all the components used in the PCB.
- PCB layout: Creating a PCB layout based on the schematic diagram and the BOM.
PCB reverse engineering is used for various purposes, such as:
- Understanding the design of a competitor’s product
- Repairing or modifying an existing PCB
- Learning from a well-designed board
- Documenting an undocumented PCB design
- Extracting information for legal or forensic purposes
