How to Use Imaging Colorimeters for FPD Automated Visual Inspection

The use of imaging colorimeter systems and analytical software to assess display brightness and color uniformity, contrast, and to identify defects in FPDs is well established. A fundamental difference between imaging colorimetry and traditional machine vision is imaging colorimetry's accuracy in matching human visual perception for light and color uniformity. This white paper describes how imaging colorimetry can be used in a fully-automated testing system to identify and quantify defects in high-speed, high-volume production environments.February 27, 2015

Epoxies and Glass Transition Temperature

Gain a better understanding about glass transition temperature (Tg) and why it is one of many factors to consider for bonding, sealing, coating and encapsulation applications. In this paper, we explore how temperature impacts the performance of polymers, why glass transition temperature is significant, and how it is measured. Tg can be an extremely useful yardstick for determining the reliability of epoxies as it pertains to temperature.January 09, 2015

3D Integration

March 2015 (Date and time TBD)

Die stacking enables better chip performance in a small form factor, meeting the needs of smartphones, tablets, and other advanced devices. Through-silicon vias are moving into volume packaging production, but problems with reliability, cost, and scaling remain. The supply chain also must adjust to this “mid” step between front- and back-end chip production. This webcast will explore the wafer thinning, bonding, TSV formation and other critical process steps necessary to enable 3D integration.
