Abstract: A board inspection apparatus system includes a first apparatus, a second apparatus, a third apparatus and an information transfer section. The first apparatus acquires first three-dimensional information of a solder paste on a board, and inspects whether the solder paste is formed good by a first tolerance based on the first three-dimensional information. The second apparatus mounts an electronic component on the board to join the electronic component and the solder paste. The third apparatus acquires second three-dimensional information of a solder joint, and inspects whether the electronic component is mounted good by a second tolerance based on the second three-dimensional information. The information transfer section transfers the first three-dimensional information to the third apparatus, or transfers the second three-dimensional information to the first apparatus. Thus, a more effective inspection condition may be established, and a rate of defect for each apparatus may be greatly reduced.
