The controlled area contains the following:
(1) Receiving inspection
(3) Necessary workstations
(4) Inspection station
(5) Separate potting facilities for epoxy and silicones
(6) Test facilities for
a. Corona testing
b. Component testing
c. Subassembly testing
Top assembly testing.
All personnel working in this area should be required to wear white cotton,
lint-free gloves. If assemblies have electrostatic-discharge-sensitive
components, they should be handled at an ESD workstation which meets the
requirement of DoD-STD-1686.
However, human safety and general high-voltage handling procedures must
take precedence over ESD procedures.
The following areas are critical and should be designed to prevent
contamination of other areas:
(1) Abrasive Cleaning - The abrasive cleaning area should be sealed and
vented to an outside area.
(2) Potting Rooms - Separate potting facilities are required for epoxies
and silicone rubber to eliminate cross-contamination. Vacuum pump exhaust
should be filtered and routed outside the area. The oven used for curing the
insulation systems should be treated the same as the vacuum pumps. The
encapsulation system should be a vacuum-transfer system with pressure- curing
(3) Cleaning Station - The cleaning station should consist of a
fluorocarbon vapor degreaser, with spray attachment and other cleaning aids
such as cleaning brushes, disposable lint-free tissues and a vacuum drying
oven for dry cleaning and removing unwanted moisture.
