78 The PCB Magazine • September 2015 Yu: What are the requirements for materials? Dong: Different changes and developments in function. Laminate will be extended from an- ti-CAF and lower CTE products to HDI, heavy copper and RF/high-frequency raw material. At the same time, it requires much stricter manu- facturing control in order to guarantee the au- tomotive safety and high reliability. In the future, automotive electronics ma- terials will have higher requirements on the reliability of products. However, new tech- nology standards adopted by various manu- facturers are different. Automotive electron- ics materials are quite different from normal consumptive electronic products, because they involve the safety of the automobile and human beings. Therefore, with regard to certain safety standards, such as thermal stability, moisture-proof, anti-CAF, low loss, etc., automotive electronics products require different and higher standards. All these re - quirements on the product formulas of glass fiber yarn, fabric, copper foil and copper clad are new technology challenges. Moreover, for the time being, all the downstream enterpris- es need to invest more funds and technology to support and match up these new technol- ogy requirements. Yu: What is Shengyi's focus in this market? Dong: Shengyi Technology is one of the impor- tant global automotive electronics' raw materi- al suppliers. Shengyi Technology will continue to take advantage of our National Engineering Research Center of Electronic Circuits Base Ma- terials, cooperating and working with the well- known automobile end users and continue to be a reliable supplier for the global automotive electronics market.

THE IMPACT OF AuTOMOTIVE TRENDS ON CHINA'S PCB SuPPLy CHAIN continues FEAturE IntErvIEw a new grant seeking to develop new tech- niques for creating high-temperature materials is taking advantage of Duke university's exper- tise in computational materials genomics—the computer modeling of novel materials to iden- tify which might have desirable properties. led by nc state university's stefano curatolo (pictured), the new initiative addresses funda- mental scientific questions that could lead to so-called "entropy- stabilized alloys." the initiative also includes the university of vir- ginia and the university of califor- nia, san Diego, and is funded by a five-year, $8.4 million grant from the office of naval research (onr). "the Defense Department has a need for materials that are mechanically and chemically stable at temperatures of 2000°c or more," says Don Brenner, Kobe steel Distinguished Professor of materials science and engineering at nc state and principal investigator under the onr grant. "these materials can have significant aerospace applications, but the number of usable materi- als is currently small, and those materials rely on strong chemical bonding to remain stable. at high temperatures, most materials are simply no longer stable." these alloys are of interest for use in ultra-high temperature ap- plications because of their unique ability to "absorb" disorder in a material's crystalline structure that otherwise would lead to the breakdown of a material.
