Abstract: Provided are an apparatus and a method for measuring a three dimensional shape with improved accuracy. The apparatus includes a stage, at least one lighting unit, a plurality of image pickup units and a control unit. The stage supports an object to be measured. The lighting unit includes a light source and a grid, and radiates grid-patterned light to the object to be measured. The image pickup units capture, in different directions, grid images reflected from the object to be measured. The control unit calculates a three dimensional shape of the object from the grid images captured by the image pickup units. The present invention has advantages in capturing grid images through a main image pickup portion and sub-image pickup portions, enabling the measurement of the three dimensional shape of the object in a rapid and accurate manner.

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.
