Managing Tester Maintenance and Performance
Test Time Comparison By Tester
Finding outlier testers in your test
fleet will improve your utilization performance and your yield. OptimalTest tools
let you know online via email/SMS that a specific tester isn’t performing well.
This can be a trigger for a maintenance action which will save your company a lot
of money and make you an important player in any factory cost reduction group
Yield comparison by probe card
Finding an outlier prober improves
your yield. OptimalTest tools let you know online via email/SMS that a specific
tester isn’t performing well. This can be a trigger for a maintenance action which
will save your company a lot of money and make you an important player in any factory
cost reduction group
Bin switching
This is a powerful tool which enables you to identify
issues and/or investigate issues both online and offline. You can improve your yield
and utilization performance significantly using our tool:
- Bin switching identification can be a result of a problematic module (tester/prober/handler/probe
card/load board). Understanding the issue is the first step toward solving it
- Bin switching identification can be a result of a test program issue. This tool
can trigger a process in which the test program is fixed, improving test floor utilization
performance (saving TT)
- Bin switching is also a tool which helps the engineer to optimize resort/retest
rules according to former data resulting in improved utilization and yield
