DECEMBER 2018 I DESIGN007 MAGAZINE 91 5 The Bare (Board) Truth: Getting on the Same Page—A Data Story E Thickness callouts for sin- gle-sided or double-sided orders are even more criti- cal. As a fabricator, we can control the thickness of the multilayer by using differ- ent combinations of pre- pregs/cores. 6 EMA Launches Ultra Librarian Reference Design Cloud E EMA Design Auto- mation announced the release of its Ultra Librarian Reference Design Cloud, giv- ing engineers easy, web-based access to reference design schemat- ics enabling faster design starts. 7 Julie Ellis: Communication and Fabrication Knowledge Critical for Designers E Field Application Engineer Julie Ellis of TTM sees it all: good designs, bad designs, and everything in between. Her classes on proper DFM techniques are always a big draw. She taught at the inau- gural AltiumLive in 2017 and was back at this year's event. I caught up with Julie and asked her to discuss some of the things she covered in class. As she points out, many issues could be eliminated if designers communicated with their fabricators and had a better understand- ing of how PCBs are manufactured. 8 New Mentor Xpedition Platform Delivers 'Shift-Left' Multi-Dimensional Verification E Mentor, a Siemens business has announced the new Xpedition printed circuit board (PCB) design platform focused on multi-dimensional verification. 9 Life Beyond 10 Gbps: Localize or Fail! E Ideally, all intercon- nects should look like uniform transmission lines (or wave-guiding structures) with the specified characteris- tic impedance. In re- ality, an interconnect link is typically com- posed of transmission lines of different types (microstrip, strip, coplanar, coaxial, etc.) and transitions between them such as vias, con- nectors, breakouts and so on. J DownStream Technologies Unveils Updates of CAM350, DFMStream and BluePrint-PCB E DownStream Technologies has announced global availability of Release 2018 for CAM350, BluePrint-PCB, and DFMStream.
