HAST Quality Testing of Epoxy Mold Compounds Based on Iodine Vapor Test and Impedance Spectroscopy

Cracks, penetration paths and adhesion weak points in insulation polymers such as epoxy mold compounds usually lead to a drastic shortening of the lifespan of the entire electronics. Particularly in humid environmental conditions, fault mechanisms such as Electrochemical Migration (ECM) or – under high-voltage conditions – the anodic migration phenomenon (AMP) are stimulated.

Our expert Stefan Strixner will show in this webinar how the protective effect of these mostly polymer-based protection systems can be quickly and qualitatively tested using the iodine vapor-based test developed by ZESTRON.

Key Topics:

Presentation of iodine vapor test (IVT) as Highly Accelerated Stress Test (HAST)
Iodine vapor test compared to conventional test methods such as MFG & FoS testing
Possibility of additional non-destructive evaluation of the systems via impedance spectroscopy (EIS) before and after iodine vapor testing
