A workpiece picking apparatus includes a robot, a workpiece recognition device for recognizing the workpieces located in a wide area, an accurate measurement device for accurately measuring the three-dimensional position of the workpiece, a workpiece select device for selecting the workpiece to be picked, and an NG workpiece storage device for storing information on the rough position of an failed NG workpiece when the measurement of the three-dimensional position or the picking for the workpiece has failed. The workpiece select device excludes the NG workpiece stored in the NG workpiece storage device and selects the next workpiece to be measured. The robot picks the selected workpiece based on the three-dimensional position of the workpiece measured by the accurate measurement device.

The present invention is a cooling plate including a groove, which becomes a passage of a coolant, inside a body, wherein one or more fins are provided inside the groove, wherein the groove is covered with a lid having width larger than the groove, wherein the lid is joined to the body by friction stir welding, and wherein a weld bead formed by the joining is outside the passage, and the weld bead formed by the joining is formed within the body and further, is characterized by a manufacturing method of a cooling plate that has a first groove, which becomes a passage of a coolant, and a second groove, which has width larger than the first groove and receives a lid on the first groove, inside a body, receives the lid on the second groove, and is joined to the body, the manufacturing method of a cooling plate wherein, while the lid and the body are joined together by the friction stir welding owing to insertion of a rotation tool having a shoulder and a pin, the joining is performed so that a weld bead formed by the joining may become out of the passage, and furthermore, is characterized in that a target for sputtering is joined to the cooling plate.

Solder paste application, inspection and correction. Following or during application of solder paste on a substrate, the result thereof is inspected and any detected errors are registered. Following an evaluation as to whether correction of these errors is required and if it would be worthwhile, the errors are corrected. The correction involves removing solder paste from locations where so required, and jetting of additional solder paste to locations where so required.

The invention describes a method of controlling a segmented flash (10) having a plurality of flash segments (S1, S2, . . . , Sn), which method comprises the steps of measuring the forward voltages (Vf1, Vf2, . . . , Vfn) of the flash segments (S1, S2, . . . , Sn); and adjusting the brightness of the flash segments (S1, S2, . . . , Sn) on the basis of the measured forward voltages (Vf1, Vf2, . . . , Vfn) to achieve a desired illumination profile (P) for the segmented flash (10). The invention further describes a segmented flash system (1) comprising a segmented flash (10) with a plurality of flash segments (S1, S2, . . . , Sn), wherein each flash segment (S1, S2, . . . , Sn) is arranged to illuminate a portion (20) of a scene (2); and a flash driver (11) adapted to perform the steps of the inventive method to adjust the brightness of the flash segments (S1, S2, . . . , Sn).
