摘要： A device for attaching conductive balls to a substrate includes a first plate, a second plate and a controller. The first plate includes first recesses. Each of the first recesses picks up a corresponding conductive ball to be attached to the semiconductor package. The second plate includes second recesses. Each of the second recesses picks up a corresponding conductive ball to be attached to the semiconductor package. The first plate and the second plate are separated from each other. The controller controls each of the first plate and the second plate to be separately moved up or down so that a lower surface of the first plate and a lower surface of the second plate are positioned differently in a first direction normal the lower surface of the first plate.

摘要： An apparatus and method for stabilizing an output of a laser is provided. An optical amplifier oscillates light having a first wavelength band. A filter filters the light having the first wavelength band to output light having a second wavelength band narrower than the first wavelength band. The light having the second wavelength band may correspond to an output of a laser. To stabilize the wavelength center of the output laser, at least a portion of the light having the second wavelength band may be transferred to a fiber Bragg Grating (FBG) through a coupler. By performing feedback of a difference between the signal output from the FBG and a laser modulation signal, an offset corresponding to a lead zirconate titanate (PZT) operating parameter of a Fabry-Perot filter may be controlled to automatically stabilize the wavelength center.
