OptimalTest has invested an enormous amount of thinking on the subject of Outlier Detection. Not only do OptimalTest tools monitor your yield on line but they also can monitor any parameter logged in order to identify excursions online.

• Yield comparison by prober
  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 will 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 will be    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

OptimalTest tools give you the option to tailor the right report per your needs. This capability will help you prepare your daily OPS report in a few minutes, including yield status
