11.4 MSA mode
MSA is Measurement System Analysis. This mode allows to record data from production mode for
MSA analysis in GraphStat software.
MSA data are saved in the supervisor MSA database (see chapter 12 Supervisor and chapter 15
GraphStat for settings and use of this MSA mode).
To start MSA mode:
1. Edit the DefaultValue .ini file and set the following keys accordingly:
2. From Vision 2007, open the .tst file to run the board.
Select some components to be followed in statistical monitoring (edit component and tick statistical

4. From Vision 2007 Production menu, tick MSA mode and start production.
5. In Production mode, press GO and load a board in the AOI system.
The same board will be executed the number of cycle defined in the DefaultValue .ini file.
Results will be saved in the database.
Bar codes will be incremented according to the panel bar code of the board: XXX_MSA1,
XXX_MSA2, ...
[MSA]
Cycle number = 30 Indicates the number of time for the sameboard to be run
0 = MSA mode menu is gray out from Production mode
Clamp/unclamp mode = 0 Indicate if the board is unclamped between each run
0 = The board is not unclamped
1 = The board is unclamped and clamped again
Even if you se-
