UCSB DFA Production Information
This page contains information relating the DFA production work at UCSB.
[Current Status] [Results from DFA Tests]
This is a table showing
the current status of DFA production. We will try to keep this table
updated on a weekly basis. For each part in our inventory, we list where
it is in the production sequence and any comments. There is also
a tab-delimited ASCII
file with summary information (finish dates of bonding, testing and
gluing to HDI).
This plot shows how much bonding we have done since January 1st, 1998, how much bonding we still need to do, and what our current status is, this plot shows our testing status, and this plot shows how closely the testing was following the bonding. Finally, a plot showing our burn-in situation is also available.
9/14/98: All class A parts have been bonded!
DFA Test Results
You can view the results of the DFA tests that have been performed so far
on all parts. You can see what parts are being tested, what tests
have been performed on each part, and the results of the tests. The
results can be viewed as either a JPG image of the LabVIEW frontpanel,
and Excel workbook which combines all of the data and calculates a bad
channel list, or as a TAB-delimitted ASCII file. Just click here
Burn-in results for D02B.13 and D03F.03

DFA Testing Fault Summary
to see a summary of the number of bad strips per DFA that we see in the DFA
tests. All fault types that we can see are counted, except for opens and
shorts on the Upilex testing tree. Please note that there are some wafer
faults which don't appear in the DFA test, like high current strips and strips
with bad bias resistors. Only parts that have finished all of their testing
and rework are included in the graphs. Parts used for special studies and
things like beam tests are not include, either.
