About AMI

The AMI evaluation system continuously measures leakage current to evaluate electrochemical migration and insulation resistance degradation in electronic components. It supports long-term reliability and lifetime testing for increasingly demanding applications such as AI servers and other high-performance electronics. Can be integrated with ESPEC temperature/humidity chambers.

NEW: AMI-SPM enables leakage current and resistance change measurements in low-voltage regions below 10V, suitable for advanced packages that operate at lower voltages.

Features for AMI Electrochemical Migration Evaluation Systems

Stress voltage options from 100 V to 2500 V

The AMI system supports insulation reliability testing across a wide range of voltage conditions. Available constant stress voltage options include 100 V, 300 V, 500 V, 1000 V, and 2500 V. Contact ESPEC for requirements above 2500 V.

Individual event detection for every channel

Dedicated event detectors monitor each measurement channel independently. When resistance drops below a predefined threshold, the system automatically begins recording measurement data at the specified interval.

Easy cable connection and maintenance

An optional connection unit simplifies measurement cable installation and removal, reducing setup time when connecting or soldering specimens. The unit can be installed on the front, left, or right side of the rack to accommodate the installation environment.

AMI measurement cable connection unit — Measurement cable for 5-channel connectors.

Monitor up to four environmental test chambers

Up to four environmental test chambers can be connected to the AMI system through Ethernet. Along with resistance and voltage measurements, chamber temperature and humidity can be monitored from the AMI system and recorded with the test results.
