Ion Migration Evaluation System AMI U

Analysis and evaluation of electrochemical migration and evaluation of insulation resistance made more accurate, efficient, and easier Evaluations of electrochemical migration and insulation resistance are assuming a greater degree of importance as electronic devices are more and more miniaturized and mounted with higher density. The Ion Migration Evaluation Systemallows these evaluations to be performed continuously with a high degree of accuracy and efficiency. Environmental testing has been successfully merged with measurements/evaluations.

AMI ION MIGRATION EVALUATION SYSTEM Makes stress evaluations and insulation resistance evaluations by electrochemical migration efficient and easy, and covers a broad spectrum, from low-voltage to high-voltage tests. Main features anode Electrochemical migration between electrodes (Electro photographic image taken with EPMA produced by JEQL) High precision measurement realized by ESPEC's unique scanner operation technology supported by continuous power supply and international standardscompatible measurement equipment.

Utility Tests simplified by the interaction of the measurement system with various environmental test chambers. Interaction with the environmental test chambers Interaction with the environmental test chambers enables accurate measurement and makes the best use of it. AMI can be connected to up to three environmental test chambers. Real-time monitoring of temperature and humidity AMI monitors and records the temp. and humid. inside the environmental t e s t c h a m b e r. D a t a a r e r e c o r d e d simultaneously with the measurement carried out by the AMI. The statistics processing...

Evaluation AMI uses a measurement method for insulation resistance that meets multiple types of test requirements; among others can be named the electrochemical migration evaluation, insulation deterioration characteristics evaluation, and so on. Electrochemical migration test Example of results obtained from the Ion Migration Evaluation System (AMI) Before starting, a preset measurement cycle (six min. minimum) is realized by the AMI, on the insulation resistance of every channel. The AMI works by onetime charging channels' voltage, thus allowing a subsequent save of time and ease of...

Evaluation Continuous measurement mode with stress voltage W h e n t h e s t r e s s volt a g e a n d t h e measurement voltage are equivalent, you can perform time-saving test by using this mode. It will use the stress voltage as the measurement voltage, without recharging by the measurement voltage. The test period is defined as the accumulated stressed time. The time for measurement (charge and measure) is not included in the test period. Voltage migration image obtained by continuous power supply scanner operation technology Stress voltage (100V), measurement voltage (100V) In the...

FAILURE RECOGNITION There are two recognition methods for all kind of failure. Limit recognition Leak Touch detection recognition By setting an absolute value, a change rate (%), or changing the amount. These three failure criteria can be used to set the threshold of your test, on each channel. “Leak Touch” detection and recognition Between the measurement interval, the leak detector can identifies any small leak on each sample by their st ress volt age. You ca n set a ny amount of leak current that AMI will then recognize as a failure. It is a ci rcuit r y tot ally apa r t f rom t he...
