5.8 Using Outgas Source options
In addition to the evaporation parameters described in the previous section, you can also
set up enhanced outgassing with the Outgas Source user parameter. This has three
settings: multiple, single or none as described in Table 10.
You need to be logged in at Administrator level to access this parameter
(see page 49).
Table 10 Outgas Source options
Setting Action
Single
outgas
Applies the outgas current for the outgas time once. If the vacuum max recovery time
is zero the coat cycle will automatically start. Otherwise, the current is turned off and
outgas recovery starts. In this period, the Q150T waits for the vacuum to return to
the level it was before the current was applied. This time is limited by the max outgas
recovery time parameter (default 10s). After this, the coating continues
automatically.
Multiple
outgas
The Multiple outgas option allows you to verify that out gassing is occurring and to
decide to continue or repeat the outgas cycle. It applies the outgas current and
outgas recovery as above. After a cycle is completed, you are prompted to (a) carry
out further out gas cycles, (b) start the coating or (c) vent the chamber.
If the vacuum is less than 0.05 mbar below the vacuum after the outgassing, the
Coat button changes to green to advise that further outgassing is not necessary.
None Skips the outgas step and waits 5 seconds for the stage to speed up before
commencing coating.
