Abstract: An inspecting apparatus and an inspecting method capable of detecting a state inside the cream solder are provided. An illumination device (5) irradiates infrared light at predetermined intensity to a board on which cream solder is applied. An image taking device (6) takes an image of the board to which the infrared light is irradiated. A main control portion (95) in a control device (9) is capable of detecting a sectional shape of the cream solder according to an intensity distribution of infrared light reflected on the board from image data of the image captured by the image taking device (6). Also, because reflected light from the cream solder surface can be eliminated by an elimination portion (95c), the sectional shape of the solder can be detected more exactly.

Abstract: Problem to be Solved To efficiently perform a board appearance inspection with a simple structure. Solution A control unit 60 performs processing for comparing a picked-up image of a board P picked up by a camera 52 with standard image data stored in a memory unit 61 and judging whether the board is good or poor. When the board P is judged to be poor, an image of the board P is displayed on a liquid crystal monitor 4 in order to have an operator visually judge the board P. When the board P is judged to be good by the visual judgment, the picked-up image of the board P that is judged to be good is additionally stored in the memory unit 61 as the standard image data.

Abstract: The shape of a cream solder is accurately detected, irrespective of a cream solder composition. An illumination setting section (95b) sets the intensity of infrared light radiated by an illuminating device (5), in accordance with the cream solder composition. An photographing device (6) irradiates a board applied with the cream solder with the infrared light having the light intensity set by the illuminating device (5). The photographing device (6) images the board irradiated with the infrared light by the illuminating device (5). As a result, an image including an image of light reflected from a surface of the board can be acquired.

Abstract: A board inspection device 1 comprises: an inspection unit 50 for inspecting a board P; a board-supplying unit 24 that enables a board P to be manually supplied to the inspection unit 50; and a liquid crystal monitor 4 for displaying prescribed information including the results of an inspection of the board P, wherein the board inspection device 1 is further provided with: a camera 52 for recognizing identification information assigned to the board P; and a control unit 60 that confirms inspection history of the board P based on the identification information acquired via the camera 52 and controls, when it is confirmed that the board P has already been inspected, the liquid crystal monitor 4 to display information to the effect that the board P has already been inspected and prohibits execution of an inspection operation on the board P by the inspection unit 50.
