The Customer needed to detect intermittent open circuit defects. The defect may exist for an unusually short time so we needed the fastest scan available for open circuit detection. |
||||
Solution |
||||
The Touch 1's normal continuous scan does a good job of finding intermittents. Still, you may have special cases where you'd like the best possible intermittents test. A custom component script: con_tst.cmp, lets you specify the maximum resistance of a conductor or the maximum allowed change in resistance of a conductor during a special scanning process of the device under test. This component is optimized for scanning speed. |
||||
Results |
||||
This script takes approximately 0.0005 seconds per conductor using a 1500V Touch 1. The high scanning speed along with the resistance threshold control creates the best possible test for open circuit intermittents on the Touch 1. |
