ISWAT detect the difference!

iswat:Action detection measurement card

Interruption event detector for reliability testing of electronic components, solder joints and electrical connections.

Application: Monitoring of electrical components by aging or stress test. The measurement card monitors and documents all events in a CSV file or database. By analyzing the data quality assurance measures can be initiated.

  • continuous monitoring
  • The detector is used in the course of aging or stress tests.

  • New developments in the materials and technologies of electronic components as well as the use of lead-free solder require reliability qualification tests to avoid premature failures.

  • Event detectors simultaneously perform continuous monitoring of the resistance on a large number of channels.

  • Events can be detected whitin less than one microsecond.

  • The detection is performed by fast comparator circuits in accordance with the test standards DTS04193EN and JESD 22a104.

  • This type of test is critical to the verification of the reliability of electronic components and assemblies for automotive, telecommunications, medical technology and consumer electronics.

Advantages of the event detector:

  • 19“ rack plug-in module 3U

  • 16 samples can be monitored by one module.

  • The modules register interrupts and report the events to a host computer via fieldbus.

  • Detecting resistance changes with a fast detector circuit. Monitoring is performed on all channels at the same time. (No scan!)

  • The detection threshold of resistance of the sample is adjustable.

  • Adjustable current source for energizing the sample.

  • In addition, the resistance value of the sample is cyclically read in by ADC.

  • Testing the functionality of the individual channels with a testborder (pulse-shaped impedance change, resistance good / bad and pulse time adjustable).
