摘要： An apparatus and method are provided for detaching a die from an adhesive film, the apparatus comprising a vacuum platform having a surface configured to support a part of the adhesive film on which the die is attached. A plurality of pre-peeling columns having substantially flat contact surfaces are projectable relative to the surface of the vacuum platform to push against the adhesive film at the position of the die to generate initial peeling between the die and the adhesive film. Thereafter, a plurality of ejector pins that are positionable relative to the pre-peeling columns are operative to push against the adhesive film at the position of the die to generate further peeling between the die and the adhesive film. The die is then removed from the adhesive film.

摘要： The position of a working point relative to a working space, such as a working point of a carriage on a gantry beam of an XY positioning table, is determined by measuring at least two sets of displacements. A first set of displacements, of the working point relative to an intermediate component, such as the gantry beam, includes a relatively large displacement (X) in a first linear degree of freedom and relatively small displacements (Y1′, Y2′), in at least two of the five degrees of freedom other than the first. The second set of displacements, of the intermediate component relative to the working space, includes a relatively large displacement (Y1, Y2), in a second linear degree of freedom, and relatively small displacements (X1′, X2′), in at least two of the five degrees of freedom other than the second.
