November 2015 • The PCB Magazine 85 5 AT&S Highlights the Future of PCB Industry miniaturisation and performance enhancement are leading trends not only for mobile devices such as smartphones; applications in the automo- tive sector and in medical technology are also get- ting progressively smaller, more efficient and more powerful. 6 n.A. PCB Book-to-Bill ratio reaches Five-year High in August total north american PcB shipments increased 1.5% in august 2015 compared to august 2014. Year-to-date shipment growth stood at -0.1, re- flecting the negative sales growth rates seen ear- lier this year. compared to the previous month, PcB shipments were up 3.6%. 7 Final Surface Finishes for Automotive: no one-Size-Fits-All Solution regardless of whether your application is automo- tive, medical or military, there are many factors to consider when selecting a final surface finish. cost, lead or lead-free requirements, end environment, shelf life, fine-pitch components, rF applications, probe-ability, thermal resistance and shock and drop resistance, to name a few. there is not a one- size-fits-all finish. understanding the advantages and disadvantages of each surface finish allows the designer to select the finish that best fits each particular application. 8 Becoming an Automotive Supplier—Proceed with Caution Possibly further fueling a growing desire in our industry towards participating in the automotive electronics sector have been further technology advancements in automobiles, as well as a tear in tesla's stock price and headlines. 9 All Flex now offers High Temp Flexible Circuits & Heaters all Flex, manufacturer of flexible printed circuits and heaters, has developed a polyimide-based ma- terial set specifically targeting the market for high temperature flexible circuits and flexible heaters. Increasing demands for high temperature applica- tions have driven the development process at all Flex over the past 18 months. J Testing Flexible Circuits, Part 2: raw Materials and Components even though the raw materials may individually meet certain specifications, it is important to de- termine if the final product configuration meets those specs, which means that testing done at the finished circuit level is also needed.
