Socket Maintenance
Setting up a Preventative Maintenance Program is important in maintaining both Socket and Test Probe
life expectancy as well as good electrical continuity which will help minimize false rejects and low test
yields. Generally, light cleaning is recommended for a preventative maintenance program of the test
socket assembly. The most effective way to determine a schedule is by tracking test yields. The
maintenance schedule should be based on when yields begin to fall below the performance of a new test
socket. Some customers perform light cleanings on a per day basis or at 20,000 or 50,000 cycle intervals.
The schedule depends on the amount of debris or contamination that the socket and test probes are subject
to.
The following items should be included in a typical maintenance program.
