December 2016 • The PCB Magazine 83 UNDERSTANDING PREDICTIVE ENGINEERING sizes and design rules can be used to create tech- nology files that drive modern CAD programs. Conclusion If companies want to reduce product gen- eration time to market, development costs and production costs, then DFM/A needs to be in- tegrated into a product generation framework. concurrent engineering, concurrent manufac- turing, product data management and predic- tive engineering all are essential elements. The tools, software and elements of such a vision are shown in Figure 9. All that remains is to find a software environment to add predictive engi- neering. PCB References 1.

Following a decade of intensive research into graphene and two-dimen- sional materials, a new semiconductor material shows potential for the fu- ture of super-fast electron- ics. Indium Selenide (InSe) is only a few atoms thick, similarly to graphene, and reported in Nature Nanotechnology this week by researchers of The University of Manchester and their colleagues at The University of Notting- ham. The new research shows that InSe crystals can be only a few atoms thick, nearly as thin as gra- phene. InSe was shown to have electronic quality higher than silicon, which is ubiquitously used in modern electronics. New Ultra-Thin Semiconductor Could Extend Life of Moore's Law
