Method for automated measurement of three-dimensional shape of circuit boards
A method of measuring a 3D shape includes the steps of measuring a brightness of a first illumination source 41a, measuring a phase-to-height conversion factor, measuring a 3D shape of a circuit board 62 according to the normal inspection mode, and determining whether bare board information about the circuit board 62 is included. If the information is not included, performing bare board teaching to acquire the information. Then, the 3D shape of target objects on the circuit board 62 are measured, when the bare board information is included or bare board teaching information is generated. Next, the circuit board 62 is analyzed to determine if it is normal or abnormal by using 3D shape information.
