PRINTED CIRCUIT BOARD INSPECTING APPARATUS METHOD FOR DETERMINING FAULT TYPE OF SCREEN PRINTER AND COMPUTER READABLE RECORDING MEDIUM

摘要

Disclosed is a printed circuit board inspecting apparatus. The printed circuit board inspecting apparatus comprises: a memory to store a machine learning-based model learned to derive at least one value indicating the relation of one or more fault types of a screen printer to an image indicating whether a plurality of solder pastes printed on a printed circuit board are abnormal; and a processor to generate at least one image indicating whether a plurality of solder pastes printed on a first printed circuit board are abnormal if an abnormality of at least one solder paste among the plurality of solder pastes is sensed by using an image for the first printed circuit board, use the machine learning-based model to acquire at least one value indicating the relation of the one or more one fault types to the generated at least one image, and determine a fault type associated with the sensed at least one solder paste among the one or more fault types based on the acquired at least one value.
