2. Review statistics information—
The statistics include such items as successful programs, continuity
failures, verify failures, etc.

Pass/fail criteria are logged for each individual programmer. This is
useful when attempting to identify a potential hardware problem with a
programmer.

3. Reset statistics—
The statistics displayed correspond to the package file and therefore to
the Socket Adapter used. When a Socket Adapter (or an individual
socket in a Socket Adapter) is replaced on a particular programmer, sta-
tistics for that Socket Adapter or individual socket must be reset.
To reset statistics, click Reset in the right-most column corresponding
to the programmer on which the Socket Adapter (or individual socket)
was replaced.
• If a Socket Adapter was replaced, reset all rows for that programmer.
• If an individual socket was replaced, reset only the row corresponding
to the replaced socket.
The R-date (reset date) is set to the current date and statistics are reset
to all zeroes.

Statistical Process Control Software (SPC)
This user-supplied software program can import the comma-delimited file
generated by the AH500 software.
1. Enable SPC—
1a) On the Handler Computer, navigate to C:\AH400_32 and open
WinAH400.ini with Notepad editor.
1b) Locate the section for SPC Logging. It will look like this:
[SPC Logging]
LoggingEnabled=FALSE
MaxFileSize=10485760
TempLogFile=C:\AH400_32\spcout.txt
1c) Set the second line value to TRUE:
LoggingEnabled=TRUE
1d) Save and close WinAH400.ini.
NOTE: In the above example the SPC logging file is saved to
C:\AH400_32\ directory. It can, however, be saved anywhere on the

Maximize Programming Yields
Occasional declines in system yields may occur during day to day operation
of the PS288. While overall yield levels can vary depending on device man-
ufacture, any short term change in yields of more than 0.5% is sufficient rea-
son for investigation of a local or immediate cause of variation. These
changes in yield can be attributed to a number of causes, including the man-
ufacture of devices, socket issues, system maintenance, and process errors.
Manufacture of Devices
Variations in the manufacture of devices may affect yields in an automated
system, such as:
Description
01 DevicesInputSystem - number of devices picked from Input media
02 DevicesInspected - number of devices inspected by Vision system
03 InspectionQuality - as percentage, compared with reference vision
04 InspectionYield
05 DevicesInsertedSocket - number of devices inserted into socket
06 SocketYield
07 ProgrammerYield
08 ProgSysYield (Yield of all programmers together)
09 DevicesProcessedMarker
10 MarkingYield
11 SystemThroughputExcWait - Starts with first device placed,
excludes wait times.
12 SystemTotalThroughputIncWait - Starts when Run starts, includes
wait times

14 AreaID - Programmer #1 = "17", Programmer #2 = "18", …,

16 TimeStamp - Date/Time of SPC log entry
17 OrderNumber - Job Name and or number
18 Package - Package File used for the job
19 VisionPRJ - Reference Vision File used for the job
