Abstract :
For vibration analysis of a printed circuit board (PCB) surface due to operation of mounted electromagnetic relay, the holographic interferometry measuring technique was applied, in which the time average method and the stroboscopic method were used and compared, along with a graphic image processing technique was applied. As the results, the microscopic displacement of PCB surface could be quantitatively measured and evaluated from the vibration pattern of the 3-D graphic image. It is shown that the stroboscopic method is useful in analysis of the vibration due to impulsive vibration
