Gerber files are a standard file format used in the electronics industry to describe the printed circuit board (PCB) images: copper layers, solder mask, legend, and more. These files contain vector image descriptions and are essential for PCB manufacturing, as they provide precise instructions for each layer of the board. The format is widely supported by PCB design software and fabrication houses, ensuring compatibility and accuracy during production. Although not directly a cybersecurity term, Gerber files can be a target for intellectual property theft or tampering, so protecting them is important in secure hardware development workflows.
