Moving Cabinet, Testhead and Accessories
This section covers how to move and unwrap the cabinet, testhead, and accessories in your clean room. All items
are wrapped in double protective vinyl covers.
CAUTION
You must ensure that no condensation occurs in the testhead. Before removing the deaeration
packaging’s vinyl cover, the testhead must adapt to the ambient temperature and humidity. If
condensation does occur in the testhead, the tester may not meet specifications.
• If the testhead has sat at the entrance of the clean room for more than eight hours, measure the
atmospheric temperature at the entrance, then wait for the corresponding time shown in
Table 4-2.
• If the testhead has sat at the entrance of the clean room for less than eight hours, measure the
atmospheric temperature of the location the testhead sat at prior to being moved to the
entrance, then wait for the corresponding time shown in Table 4-2.
Example:
If the temperature of the air outside is colder than the entrance, and you move the testhead to
the entrance after it has sat in a cold place for a long time, you need to check the atmospheric
temperature at that place, and then wait for the corresponding time shown in Table 4-2.
The correspondence with the waiting time for no-condensation is shown in Table 4-2.
