SpaceTech‘s headquarter disposes of 3 different cleanrooms, each with a different AIT focus:
- Cleanroom G3 (118 m² and 5.75 m ceiling hight) - for integration of larger structures
- Cleanroom G1a (78 m²) - includes the Optics Lab and Thermal Vacuum Test chambers
- Cleanroom G1b (20 m²) - for manufacturing and assembly of smaller equipment
The biggest cleanroom is mainly used for assembly and integration of larger structures (booms, solar panels, deployment mechanisms etc). It offers a total of 118 m² floor space, a height of 5.75 m over 78 m² (high-bay), and guarantees a cleanliness class ISO 8. The cleanroom is connected to an adjacent check-out room(32 m²) and the outside access hatch for delivery of flight hardware. An additional floor hatch allows for a direct transfer of hardware to the mechanical test facility below (shock and vibration test).
The second cleanroom is mainly used for instrument AIT activities. One part of the cleanroom houses the Optics Lab with several optic tables and opto-electronic devices, where a cleanroom tent (cleanliness class ISO 7) and a flow box (cleanliness class ISO 5) guarantee the optimal environment for particle sensitive optical components. In addition, the cleanroom accommodates several vacuum chambers for thermal vacuum tests.
The smallest cleanroom possesses 3 work places and is equipped with various microscopes and manufacturing tools. It presents an optimal working area for glueing processes and fine mechanics (e.g. CESS projects)
