  • Patent number: 11328407
    Abstract: A printed circuit board inspection apparatus can inspect the mounting state of a component by generating depth information on the component mounted on a printed circuit board by using a pattern of light reflected from the component and received by an image sensor, inputting the generated depth information into a machine-learning-based model, obtaining depth information with reduced noise from the machine-learning-based model, and using depth information with reduced noise.
    Type: Grant
    Filed: February 26, 2019
    Date of Patent: May 10, 2022
    Assignee: KOH YOUNG TECHNOLOGY INC.
    Inventors: Se Rin Lee, Jin Man Kang, Joong Ki Jeong, Jung Ho Son, Min Cheol Yoon
  • Patent number: 11244436
    Abstract: A printed circuit board inspection apparatus can inspect a mounting state of a component by generating depth information on the component by using a pattern of light reflected from the component mounted on a printed circuit board received by an image sensor, generating two-dimensional image data for the component by using at least one of light of a first wavelength, light of a second wavelength, light of a third wavelength, and light of a fourth wavelength reflected from the component received by a first image sensor, inputting the depth information and the two-dimensional image data for the component into a machine learning-based model, obtaining depth information with reduced noise from the machine learning-based model, and using the noise-reduced information.
