Baccini Screen printers Printers and Dryers for Sale

Serial number: 900140650010
Integrated printers and dryers for the production of 156 mm square solar cells.
The integrated dryers and printers are fed via a Jonas and Redmann loader.
The J and R loader actually loads onto a Chip and Crack detection system, which then feeds into the first printer.
3 printers
2 Dryers
Soft Line.
All manuals, drawings and software disks included.
Loaders: Printer 1 Dryer 1 Printer 2 Dryer 2 Printer 3
Operational prior to de-installation
In-line with Baccini Solar Cell Line 156mm
Single Lane process.
Attached also is the layout of the complete line.
The loader for the line is manufactured by Jonas and Redmann.
The 3rd printer unloaded directly onto the input table of the Centrotherm Fast Firing Furnace, which was the next element in the line.
The printers and dryers were re-furbished, re-located and re-installed by Applied Baccini in 2011.
Attached is the install report.
Following re-installation, only a very small quantity of pilot production was run.
The line was de-installed in february 2012.
The line has been dis-assembled and cleaned.
It is now in storage in Singapore Woodlands.

This system is used for the production of solar cells by the silk-screen printing process.
This process allows the production of:
-Conductors
-Resistors
-Dieelectrics
-Glass protections
-Cross-overs
The loading of the system is carried out by a conveyer with vision system. Wafer cells arrive from a conveyer to a Baccini
conveyer and here, by a vision system the cells are aligned and put on a walking beam, by adjusting the speed of the first
conveyer you can obtain loading heaps of 4 or 6 cells.
Printing head resolution is approx 0.5nm
