Supply Chain Maintenance Using Reverse Engineering
Bill Cardoso, Creative Electron
Bio
Bill started his first company in Brazil at age 17 and sold it a few years later when invited by the US Department of Energy to work at Fermi National Accelerator Laboratory (Fermilab) to do nuclear and high energy physics research. As the Department Head for Systems Engineering and after a 10-year long career at Fermilab, Bill moved from Chicago to sunny California to start Creative Electron. True to the American Dream, Creative Electron quickly grew from Bill’s garage to the largest US manufacturer of x-ray machines for the electronics industry (no longer in his garage). At Creative Electron Bill leads the team of engineers who designs and manufactures x-ray systems that are shipped worldwide. Starting with an associate degree at age 13, Bill has a BS, MS, and PhD degrees in Electrical and Computer Engineering and an MBA from The University of Chicago. An industry thought leader, Bill has been recognized as IIT's 2011 Outstanding Young Alumnus Awardee for his contributions to science and technology. He is also a Senior member of the Institute of Electrical and Electronics Engineers (IEEE), Surface Mount Technology Association (SMTA), American Physics Society (APS), and the International Society for Optics and Photonics (SPIE). Bill is the president of the SMTA San Diego chapter and member of the technical committee for SMTA International, SMTA Counterfeit Conference, and SMTA LED Conference, Components for Military and Space Electronics Conference, SPIE Photonics, and the IEEE Nuclear Science Symposium. He is the author of over 120 technical publications, a contributor to 2 books, owner of a few patents, and a frequent speaker at technical conferences.
Abstract
The loss of intellectual property (IP) related to electronic circuits and systems is a critical challenge in maintaining the supply chain of military programs. According to the DMEA, the B-2 Bomber encountered more than 140 obsolete components and submodules that could not be acquired for the B-2 Radar Warning Receiver (RWR). In addition to system age issues, design IP and support documentation for critical parts had been lost. With programs expected to live much longer than originally planned, it is not reasonable to expect that OEMs can support every version of a product that they have ever developed indefinitely. Sometimes the OEMs don’t even exist long into a program’s life cycle and the IP is then lost forever. In this paper, we will present a non-destructive alternative to reverse engineering. The technology presented starts with the micro computed tomography (CT) of the sample. The CT volume is then used to generate slices of the sample, which then allows us to identify the different layers of the printed circuit board as well as the location and identity of critical components on the board. These layers are then used as input to ScanCad, a software that can recreate complete schematics from the layers of the PCB. Detailed case studies will be presented to demonstrate the strengths and weaknesses of this non-destructive reverse engineering process.
About Creative Electron
Creative Electron was founded in 2008 with a simple mission: to build the best x-ray inspection systems in the world. The company manufactures and distributes high performance, off the shelf and custom x-ray inspection systems used for quality assurance, material conformity, and counterfeit detection in a wide range of applications.
