M2H
- The M2H semi-automatic screen printer has been designed for printing of ceramic hybrids in applications with small to medium size production volumes, R&D and laboratory as well as proto-typing purposes.
- But also a large variety of other flexible and rigid substrates up to a size of 180 x 160 mm can be processed on the M2H. The substrates can be placed on to different types of print nests mounted on the horizontally moving table. For a convenient substrate alignment, the printer can optionally be equipped with the manual optical positioning system MOPS. The substrate is then manually aligned using high resolution cameras for reliable recognition of fiducials or other layout features.

XH-STS
- The XH STS stencil and screen printing system was specially developed for printing substrates in thick film applications. The flexible system can be used in a wide number of areas within the hybrid, SMT and solar fields. The automatic offljne prjnt system is particularly suitable for thickfilm printing of small to mid-range production volumes which require highest precision and short tooling times.
- A porous stone is used as the standard print nest which means that all flat substrates can be positioned on the pant table, independent of their form, Even very thin materials such as wafers,solar cells. tapes or foils can be accurately printed. An additional advantage is that the incurred costs for specific print nests can be avoided Customer-specific pant nests are available upon request.

XW-STS
- The flexible machining cell is designed for front or back side printing (bumping or wafer backside coating) on round wafers. The system consists of two main modules, a loading unit and a printing system. The loading unit in turn consists of three components a magazine unloading system, a robot unit and a pre-align station.
- The magazine unloading system is equipped with two magazine positions from where the wafers are fed to the machine. The 3-axis robot unit with vacuum end effector ensures a stress-free wafer transport. Using a flexible pick-up, different end effectors can be used even for very thin or curved wafers.
