Electro-chemical Migration Evaluation System

Overview of Equipment:

More accurate evaluation of insulation resistance

As electronic devices become smaller and denser, electro-chemical migration evaluation and insulation evaluation have become more important. This system can constantly monitor these evaluations more accurately and more efficiently. This system enables easy and efficient insulation resistance evaluation and life evaluation when electro-chemical migration occurs, and it has various applications, from low voltage testing to high voltage testing.
