The spray chamber is currently built in two configurations. A manual system
capable of handling parts up to a size of three feet in any dimension utilizing
a single manually held and controlled spray nozzle. Parts are manually loaded
onto a tray in the spray chamber.
The second configuration is capable of handling hardware up to five feet in
any dimension and is more automated. This system has three spray nozzle arms
(two horizontal and one vertical) with individually controlled nozzle heads. The
nozzle head positions are easily changed out and manually set for alcohol or
other cleaning/drying media flow. The flow rate and time, and nozzle selection
can be preprogrammed on a numeric control panel contained within the control
subsystem. Parts are manually loaded onto a transfer loading cart which mates
with the cleaning chamber allowing transfer of the part from this cart onto a
turntable assembly in the chamber. This turntable assembly can be stationary or
mobile (again controlled by the control subsystem).
A final feature of this system is the "in-situ" analysis capability utilizing
a liquid particle counter and residual gas analyzer for particulate and
molecular contamination analysis, respectively.
