Selecting a Wedge Bonder – Tutorial

Palomar/Hughes started designing and manufacturing wedge bonders in the early 1980s for the aerospace and defense industries. Later, these machines were used for a wider array of applications beyond just military, including medical devices, RF/Wireless packages, automotive sensor systems, and optoelectronic systems and components. Ultrasonic wedge bonding was introduced in the early

Are Power Planes Necessary for High Speed Signaling?

The performance of a system depends heavily on the communication speed between integrated circuits, which is constrained by the power delivery networks (PDNs). The disruption between the power and ground planes based on the low target impedance concept induces return path discontinuities during data transitions, which create displacement  current  sources

Challenges in Measuring Theta jc for High Thermal Performance Packages

This is a guest post by Jesse Galloway and Ted Okpe of Amkor Technology. Article reprinted from May 2014 Electronics Cooling magazine.

One of the more challenging thermal resistance measurements to make for electronic packages is the junction-to-case resistance called Theta jc. The equation for Theta jc, equation (1), is straightforward.
