12 PCB007 MAGAZINE I MAY 2021 • Joe O'Neil, CEO, Green Circuits • Leslie Weinstein, founder/CEO, CMMC Consulting Follow this link for an IPC staff interview with Mike Carano, who provides an overview of the TLP program, how it supports industry's migration to factory of the future, and plans for the future projects. More information about the IPC ought Leaders Program, including a dedicated web- page, will be available soon. Please direct any questions regarding the program to Chris Mitchell, IPC vice president of global govern- ment relations at ChrisMitchell@ipc.org. PCB007 Dr. John Mitchell is president and CEO of IPC. To read past columns or contact him, click here. IPC's ought Leaders Program will be chaired by Mike Carano, VP of technolo- gy and business development at RBP Chemi- cal Technology and a member of IPC's Hall of Fame. He will lead a diverse group of individu- als, namely: • Olivier Coulon, consultant, Decision Etudes & Conseil • Payman Dehghanian, assistant professor of electrical and computer engineering, e George Washington University • Bryan Erwin, managing partner, BlueWave Merchant Partners • Denny Fritz, consultant • Savita Ganjigatti, VP of Engineering, Sienna ECAD Technologies • Carol Handwerker, professor of materials engineering, Purdue University • Matt Holzmann, president, CGI Americas • Meredith LaBeau, director of process engineering, Calumet Electronics Seeing through smog and fog. Mapping out a per- son's blood vessels while monitoring heart rate at the same time—without touching the person's skin. Seeing through silicon wafers to inspect the quali- ty and composition of electronic boards. These are just some of the capabilities of a new infrared imag- er developed by a team of researchers led by elec- trical engineers at the University of California San Diego. The imager detects a part of the infrared spec- trum called shortwave infrared light (wavelengths from 1000 to 1400 nano- meters), which is right outside of the visible spectrum (400 to 700 nano- meters). Shortwave infrared imag- ing is not to be confused with thermal imaging, which detects much longer infrared wavelengths given off by the body. The imager works by shining short- wave infrared light on an object or area of interest, and then converting the low energy infrared light that's reflected back to the device into shorter, higher- energy wavelengths that the human eye can see. "It makes invisible light visible," said Tina Ng, a professor of electrical and computer engineering at the UC San Diego Jacobs School of Engineering. While infrared imaging technology has been around for decades, most systems are expensive, bulky and complex, often requiring a separate cam- era and display. They are also typically made using inorganic semiconductors, which are costly, rigid and consist of toxic elements such as arsenic and lead. The infrared imager that Ng's team developed overcomes these issues. It combines the sensors and the dis- play into one thin device, making it compact and simple. It is built using organic semiconductors, so it is low cost, flexible and safe to use in bio- medical applications. It also provides better image resolution than some of its inorganic counterparts.
