Abstract
A workpiece is transported using a porous belt, which belt delivers a workpiece to a chuck, upon which the workpiece is held by vacuum. The belt can be porous PTFE. A flexible stamp is preheated, before it is applied to a workpiece, by drawing the stamp toward a heated plate, for instance by vacuum.
