A PCB reference ruler is a tool that is used to measure and locate various features on a printed circuit board (PCB). It is typically a thin, flexible strip of plastic or metal with a series of markings on it that correspond to various dimensions and features on a PCB. The ruler may have markings for common PCB dimensions, such as track widths, hole sizes, and component spacing. It may also have reference points for locating various features on the PCB, such as mounting holes, component pads, and test points. PCB reference rulers are commonly used by electronics engineers, technicians, and hobbyists when designing, building, or troubleshooting PCBs.
