Abstract

A workpiece carrier for supporting a plurality of workpieces, the workpiece carrier comprising a supporting body including a plurality of workpiece support elements, each for supporting a workpiece and providing for individual positioning of the same, the workpiece support elements each including at least one biasing element for applying a biasing force to an edge of the respective workpiece, at least one first cam for acting on an edge of the respective workpiece at a first location against the bias of the at least one biasing element, and at least one second cam for acting on an edge of therespective workpiece at a second location against the bias of the at least one biasing element, wherein the at least one first cam and the at least one second cam are operable such as to enable the position of the respective workpiece to be set relative to the supporting body.

Description

technical field [0001] The present invention relates to a workpiece carrier for carrying a plurality of workpieces, and a workpiece positioning system and method for individually positioning workpieces carried by the workpiece carrier. Background technique [0002] Continuing advances in electronics have allowed more complex systems to be contained in smaller components, resulting in the use of smaller printed circuit boards. An example is mobile phones, smaller and smaller mobile phones are being developed that have at least the same functionality, if not increased functionality. [0003] Traditionally, when dealing with small printed circuit boards, the convention has been to fabricate the printed circuit board as a series of panels that are separable within a single large board, allowing the printed circuit board to be handled as a single entity. This approach has been used successfully, but the increased precision required by newer and smaller components cannot be achie...
