Workpiece referencing system for and method of referencing workpieces supported by a workpiece carrier

A method of referencing a plurality of singulated workpieces, the method comprising the steps of:

• providing a workpiece support assembly for supporting a plurality of singulated workpieces, wherein the support assembly comprises a plurality of support members which are each configured to support an individual one of said singulated workpieces thereon, wherein the support members each comprise a support, a body which includes a support surface which supports a workpiece thereon and a resilient coupling which resiliently couples at least a part of the body relative to the support, such that the at least part of the body is displaceable relative to the support from a first, unbiased position to a second, biased reference position, and, when released, the at least part of the body returns to the first, unbiased position;
• providing workpieces onto the support surfaces of the support members;
• referencing the workpieces to predetermined positions in the horizontal orient by displacing the workpieces and the at least part of the body of each of the support members supporting the same in at least a horizontal orient from a first, unbiased position to a second, biased reference position, at which a processing operation, optionally a screen printing operation, is performed;
• releasing the at least part of the body of each of the support members, whereby the resilient couplings of the support members return the at least part of the body of each of the support members to the first, unbiased position;
• and
• removing the workpieces from the support surfaces of the support members.
