Abstract:
1. A method of fabricating a crystal oscillator comprising: applying an adhesive to an electrode pad connected to a wiring pattern, the applying applies the adhesive on a side of the electrode pad opposite the wiring pattern; acquiring image data of the electrode and a vicinity of the electrode by a optical unit; detecting a size and a position of the adhesive by using the image data; determining a position of a circle including the adhesive, the circle having a minimum radius sufficient for the adhesive; determining whether the adhesive is in an area outside of the electrode pad by using a position of the circle; removing at least part of the adhesive in the area outside of the electrode pad using a laser beam when a portion of the adhesive is determined to be in the area outside of the electrode pad; and disposing an electrode of a crystal resonator on the adhesive applied to the electrode pad.
