All performance specifications stated, including but not limited to, pump-down rates and vacuum levels make the following assumptions:
- The Vacuum Chamber is empty.
- The Vacuum Chamber and other system components are clean and dry.
- The System is being operated at Sea Level
- The ambient temperature is 18°C +/- 2°C
- All system components, including those not supplied by Abbess, are appropriate for the system and are functioning properly.
- The specifications are not impacted by the properties of your product.
If you require performance specifications for conditions other than those listed above, it is vital that you make this known to Abbess Instruments in writing. Generally Abbess Instruments recommends choosing chamber and pumping system qualities capable of achieving a theoretical vacuum at least an order of magnitude better than the desired operational vacuum.
It is to be noted that a specification described as '10-5 Torr' is a range, and means the clean, empty, dry chamber system is capable of reaching some undetermined value between 1.0x10-5 and 9.9x10-5 Torr: The (clean, empty, dry) chamber is deemed compliant whether its As-Built base vacuum is 1.0x10-5 Torr or 9.9x10-5 Torr. It does not mean that the chamber is guaranteed to reach every level within that range.

Vacuum Chamber with Robotic Dispensing and Touch Screen Interface
The Abbess Instruments Vacuum Dispensing Chamber System is designed to meet manufacturing process needs for calibrated multi-dosing of transistor plotting material under vacuum.
A custom fabricated parts matrix tray and rack system loads into a large chamber environment while the vacuum system first degasses the plotting material in a separate cylindrical chamber. Once the plotting material is degassed and the process specified level of vacuum is achieved in the larger chamber, the plotting is then conveyed to the parts by means of feedthru tubing to a positive displacement dosing pump. This travels across the parts matrix by means of an x-y motion apparatus.
Monitoring and control of the system is carefully attuned to the customer’s specified process needs. Operation is configured to both optimize production time and assure the proper cycling of vacuum equipment. Vacuum degassing and multi-dose plotting times are integrated into the equipment control sequence and real time video monitoring of the parts and material in production and touch screen computer interface allow for continuous operator involvement in the process.
