Abstract: Disclosed is a machine for transferring electronic components onto electronic cards (4), including: a conveyor (1) on which the electronic cards (4) file past in succession, and sensors (3) disposed along the conveyor in such a way as to determine the position of the electronic cards (4) filing along the conveyor (1). The density of the sensors (3) along the conveyor (1) is sufficiently high such that an electronic card (4) does not leave the field of a sensor (3) before it has entered the field of another sensor (3), over at least a part of the length of the conveyor (1).

Abstract: A method and apparatus for calculating distance in an assembly operation. The method includes the steps of providing an assembly comprising a first part, a second part and a driver coupled to the first part. The driver arranged to selectively move the first part relative to the second part. The method also includes actuating the driver to selectively move the first part between a first known position and a second position and registering speed and/or acceleration data of the driver between the first known position and the second position. The time interval for the first part to move between the first known position and the second position is measured. The distance moved by the first part between the first known position and the second position using the measured time interval and the data registered from the driver can then be calculated.

The method comprises the steps of providing an assembly comprising a first part, a second part and driver means coupled to the first part. The driver means are arranged to selectively move the first part relative to the second part.
