Espec Ion Migration Evaluation System

Features of Ion Migration Evaluation System

The ion migration evaluation system systemizes the environmental test chamber and measurement/evaluation system. It offers continuous, accurate and effective ways to collect insulation resistance data by applying stress voltage over specimens under specific temperature and humidity condition. It detects changes in insulation resistance with high precision and excels in detection of leak current. Flux, resist, solder, resin, conductive adhesive and other materials related to high density PCBs, BGA, CSP and fine-pitch pattern IC packages are suitable for evaluation.

The ion migration evaluation system integrated with two modules. They are Environmental Chamber PL-2KPH and Measurement Unit AMI-050-P.
