Cost-Effective localization of shorts and leakages in device packages and PC boards

The Magma Scanning SQUID Microscope (SSM) is a single magnetic sensor system that creates current images of devices at the package and PC board level. The SSM tool utilizes a super-conducting quantum interference device, or SQUID, to detect currents in devices requiring only nanoamps of current. These currents are assembled into an image which can be used in conjunction with optical fiducials and design data to localize static defects in three dimensions.

Imaging with the SQUID is non-destructive. As magnetic fields permeate most materials used in typical devices, there is no need to deprocess the device in any way to begin localizing the failure. Additionally, using such small currents can protect the device under test from further damage and may be the only option when trying to detect failures in circuits with very high resistance (>100kΩ). Typical failures that can be analyzed with the SSM tool include shorts, leakages and resistive opens. The system can be used to image AC and/or DC magnetic fields (and likewise, currents) depending on the requirements of the device.
