Printed Circuit Boards (PCBs), used within nearly every electronic product in the world, are physical carriers for electronic components and provide conductive pathways between them. Created as a sandwich of alternating copper and insulating substrate layers, PCBs can reveal clues about system functionality based on layout heuristics or how components are interconnected. By accessing each individual copper layer of a PCB, one can clone the design, identify areas where new features/capabilities can be inserted, locate specific connections/interfaces, or derive how a product works by creating a schematic diagram. In this presentation, Joe examines a variety of inexpensive, home-based solutions and state-of-the-art technologies that can facilitate PCB reverse engineering through solder mask removal, delayering, and non-destructive imaging.
