Wire bonding device, maintenance method and non-transitory computer-readable recording medium recording program

A maintenance method for notifying information regarding maintenance of a wire bonding device, the maintenance method comprising:

• a step of acquiring time-series data of a diagnosis result regarding an operation of the wire bonding device for a plurality of maintenance items, calculating a function that approximates a transition of a change from the diagnosis result in an initial state, and predicting the transition of the change from the diagnosis result in the initial state, wherein the plurality of maintenance items include cleaning and calibration of the wire bonding device, and the transition of the change from the diagnosis result is selected from XYZ Lissajous, XYZ deviation, XY guide, Z load, US impedance, US frequency, US calibration, and CL load, the diagnosis result comprises data derived from an XYZ Lissajous waveform of the operation of the wire bonding device;
• and
• a step of setting a time point at which it is predicted that an amount of change from the diagnosis result in the initial state for the plurality of maintenance items reaches a first threshold value as a time point for performing the maintenance of the wire bonding device for each of the plurality of maintenance items.
