Electrochemical Migration Evaluation System (Leakage Current Evaluation System)

Overview of Equipment

More accurate evaluation of insulation resistance

With the advancement of AI, 5G, data centers, and other technologies, there is growing emphasis on improving the insulation reliability of board wiring technology across a wide range of low and high voltages.
This system can constantly monitor these evaluations more accurately and more efficiently. This system allows for easy and efficient evaluation of electronic component life such as electrochemical migration, as well as insulation resistance (leakage current measurement).

Features

Tests from low-voltage to high-voltage ranges can be conducted: The optimal stress power supply can be selected for insulation evaluation in AI, communications, and energy markets, as well as under a variety of environmental conditions.
In addition to constant stress voltages of 100 V, 300 V, and 500 V, high voltage specifications of 1000 V and 2500 V are also available. (Contact ESPEC for voltages above 2500 V.)

Uniquely designed event detectors: Espec original event detectors are used to monitor each and every channel.
Once the resistance drop below the predefined threshold, it will direct the measuring equipment to begin recording at a set interval.

Improved workability and higher efficiency at regular part replacements: By installing a connection unit, measurement cables can be easily installed and removed, improving work efficiency such as when soldering to samples. The connection unit can be installed on the front of the rack or on the left or right side depending on the installation environment.

Used for each 5 ch connectors.

Real-time monitoring of 4 environmental test chambers (via Ethernet connection): Up to 4 environmental test chambers can be connected and tests performed. In addition to the resistance and voltage values, linking with an environmental test chamber allows the temperature and humidity in the test area to be monitored on the AMI side. The monitoring information is recorded in the measurement result file.
