Ion Migration Evaluation System (AMI Series)

Insulation Resistance Evaluation System

Detects decline of insulation resistance by continuous measurement while applying voltage under high-temperature, high-humidity conditions. Interaction with the environmental test chambers enables accurate measurement and makes the best use of the test chambers.

Features

Excels in detection of leak current
The leak-touch detection function detects the Occurrence of ion migration in microsecond intervals. It immediately shuts off stress voltage to the channel when leak-touch is detected. You may choose whether to continue testing after detection (optional)

Precise insulation resistance
Measurement over a wide range of 2 x 10⁵ to 1 x 10¹³ Ω at end of the 3m measurement Cable (for AMI-025-S)

Applications

• Ion migration evaluation
• Insulation deterioration characteristics evaluation
• Printed wiring board and high density mounted materials such as flat, PCB, resist, solder, resin and electrically conductive adhesive.
• Fine pitch pattern IC packages such as BGA and CSP
• Capacitor, connector and other electronics parts and materials
• Moisture absorption characteristics evaluation of various insulating materials
