1. A method for depositing viscous media on a workpiece, the method comprising:
moving at least two depositing head assemblies in three dimensional space, the moving including
moving a first of the at least two depositing head assemblies along a first beam arranged above a platform holding the workpiece, and
moving a second of the at least two depositing head assemblies along a second beam arranged above the platform and in parallel with the first beam; and
depositing the viscous media on the workpiece at least one of concurrently and simultaneously by the at least two depositing head assemblies, the depositing including
shooting droplets of mutually different types of viscous media, at least one of the mutually different types of viscous media is a solder paste and at least one other of the mutually different types of viscous media is not a solder paste.
