Magnetic test technique could help ensure microelectronics reliability

Magnetic test technique could help ensure #microelectronics reliability!

The fixtureless and noncontact technique, known as the magnetically actuated peel test (MAPT), could help ensure the long term reliability of electronic devices, and assist designers in improving resistance to thermal and mechanical stresses. "Devices are becoming smaller and smaller, and we are driving them to higher and higher performance," said Suresh Sitaraman, a professor in the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology. "This technique would help manufacturers know that their products will meet reliability requirements, and provide designers with the information they need to choose the right materials to meet future design specifications over the lifetimes of devices." Sitaraman and doctoral student Gregory Ostrowicki have so far used their technique to measure the adhesion strength between layers of copper conductor a...
