Acoustic Flatness Measurement Enhances Die Attach Analysis of Power Device

Posted on 17 July 2019

      An ultrasonic transducer raster-scans the flat surface Thermal management is always a concern when using power devices. Acoustic micro imaging looks nondestructively at the internal features of power devices; specifically, this method images the interfaces between materials. The quality of the bond at an interface, and the presence or absence of delaminations [...]

Posted on 17 July 2019

      This can save the environment while improving customer experience The awareness of environmental impact has extended to the segment of portable electronics. Consumers increasingly demand better performance and “sexy” industrial designs. At the same time, they expect products to minimize any negative impact on the environment. By George Paparrizos, Director, Product Marketing, [...]

Application Guides the MOSFET Selection Process

Posted on 17 July 2019

      Packaging can certainly impact conduction loss Given the maturity of MOSFETs, selecting one for your next design may seem deceptively simple. Engineers are familiar with the figures of merit on a MOSFET data sheet. Selecting a MOSFET requires the engineer to use their expertise in scrutinizing different specifications for individual applications. By [...]

A Better Shade of Green
