Abstract: A three-dimensional measurement apparatus measures measurement targets placed in a target measurement area on a measurement object. The apparatus includes: a measurement module that: is positioned with respect to the target measurement area, and includes: a first irradiator that irradiates the target measurement area with predetermined light for height measurement; a second irradiator that irradiates the target measurement area with predetermined patterned light for three-dimensional measurement; and an imaging device that takes an image of the target measurement area; and a control device that moves the measurement module in a height direction and successively positions the measurement module at a predetermined height position determined by mapping, and performs, based on image data taken by irradiating the target measurement area with predetermined patterned light, three-dimensional measurement to the measurement targets at the predetermined height position.

Abstract: A screen mask inspection device inspects a screen mask including a screen opening that forms a printing pattern, and includes: an inspection control device that detects solder position information of a solder paste printed on a substrate via the screen opening, and based on the solder position information, determines whether a quality of printing using the screen mask is good or bad, the solder position information being based on an amount of positional misalignment of the solder paste actually printed on the substrate relative to a predetermined reference position.

Abstract: A solder printing inspection apparatus for inspection of solder printed on a circuit board has a multiplicity of lands for mounting of electronic components. The apparatus includes an irradiation unit for irradiating a light on the circuit board, an imaging unit for imaging the circuit board irradiated by the light, a solder bridge detection unit for detecting a solder bridge connecting two of the lands based on an image data imaged by the imaging unit, a distance calculation unit for calculating a bridge distance as distance between two lands contacting the solder bridge or solder bridging regions or solder detection frames corresponding to the two lands contacting the solder bridge, and a distance determination unit for determination of whether or not the bridge distance is within a permissible range.
