We develop a printed circuit board (PCB) measurement system to measure the line width, the angle between two lines, the pad diameter and the pad center position. We present the hardware constructions and the software design scheme. We propose the key algorithms on the measurement of the line width and pad parameters. The origin of measurement error is discussed. The solutions to reduce the measurement error are proposed. Experimental results demonstrate that the system is efficient and its measurement error is less than 2 mum. The system has been applied to manufacturing printed circuit boards and brought good social and economic benefits.
