Abstract
An electronic component inspection apparatus includes a light source arranged in a mounting area where at least one electronic component is mounted to a board and a light-receiving sensor arranged outside the mounting area to detect an intensity of a light received from the light source. A computer executes a program to perform a process of determining a state of joining parts in the mounting area based on a result of comparison of the intensity of the light received by the light-receiving sensor with an intensity of distribution previously acquired.
Claims9
An electronic component inspection apparatus comprising:
- a light source disposed in a mounting area where at least one electronic component is mounted on a board;
- a light-receiving sensor disposed outside the mounting area and configured to receive a spectrally dispersed light having a wavelength in a predetermined wavelength range after a light emitted by the light source passes through spaces between joining parts in the mounting area, and detect an intensity of the spectrally dispersed light;
- and
- a computer configured to
- acquire an intensity distribution of the spectrally dispersed light by performing spectral analysis on the intensity of the spectrally dispersed light detected by the light-receiving sensor,
- compare the acquired intensity distribution with a previously acquired intensity distribution, and
- determine a state of the joining parts based on a result of the comparison.
An electronic component inspection method, comprising:
- emitting a light from a light source disposed in a mounting area between a board and at least one electronic component mounted on the board toward a periphery of the mounting area;
- receiving, by a light-receiving sensor disposed outside the mounting area, a spectrally dispersed light having a wavelength in a predetermined wavelength range after the light emitted by the light source passes through spaces between joining parts in the mounting area, to detect an intensity of the spectrally dispersed light;
- acquiring, by a computer, an intensity distribution of the spectrally dispersed light by performing spectral analysis on the intensity of the spectrally dispersed light detected by the light-receiving sensor;
- comparing the acquired intensity distribution with a previously acquired intensity distribution;
- and
- determining a state of the joining parts based on a result of the comparison.
