Abstract: A method for placing at least one component provided with connection points on a substrate. First, positions of the connection points are determined, after which the component is positioned at desired positions on the substrate with the connection points thereof. Upon placement of a number of components, the contour of a component as well as the positions of the connection points relative to said contour are determined for a first number of components. On the basis of the calculated positions of the connection points relative to the contours average positions of the connection points relative to the contour are calculated. Upon placement of a second number of components the contour of a component is determined, whereupon the expected positions of the connection points relative to the contour are calculated on the basis of said average positions.
Abstract: A device suitable for placing a component on a substrate is provided with a component feeding device, a component pick-and-place device comprising a nozzle, a substrate carrier, means for moving the component pick-and-place device from the component feeding device to the substrate carrier and vice versa, as well as a global measuring system for determining the position of the component pick-and-place device during movement of the component pick-and-place device from the component feeding device to the substrate carrier and vice versa. The device is further provided with a local measuring system, remote from the global measuring system, for almost continually determining, in the proximity of a desired position of the component on the substrate, the position of the component pick-and-place device with respect to the substrate, which local measuring system is located closer to the substrate carrier than the global measuring system.
Abstract: A device suitable for producing an image of an object disposed in an object space by means of a sensor comprises at least the sensor, a first lens assembly disposed in front of the sensor, a stop plate comprising a light passage disposed in front of the first lens assembly, a second lens assembly disposed in front of the stop plate and the object space disposed in front of the second lens assembly. The device further comprises a light source, as well as a diffuser which is disposed on a side of the object space that is averted from the light source.
Abstract: A moving device comprises at least a first element which is movable in a direction of movement by means of a drive unit, which first element at least comprises at least one first magnetic part. The moving device further comprises a second element, with respect to which the first element is movable at least from at least one operative position spaced from the second element to a rest position near the second element. The second element comprises at least one second magnetic part, which is polarized in a polarization direction opposed to the polarization direction of the first magnetic part. The polarization directions extend transversely to the direction of movement and also transversely to surfaces of the first and second elements that are positioned opposite each other in the rest position.
Abstract: A method of establishing at least one marking element on a substrate (1). By means of design data of the substrate (1) at least a fictitious marking element (5) on the substrate (1) is determined. The fictitious marking element (5) should then be unique for a predefined area of the substrate (1). The fictitious marking element is obtained by selecting at least two transitions (6, 7, 17, 18) of at least one element on the substrate while the transitions (6, 7, 17, 18) enclose an angle to each other.
