72 The PCB Magazine • June 2016 Beyond FR-4: High-Performance Materials for Advanced Designs, Part 1 In the past 40-plus years of PCB manufacturing, the primary material of choice has overwhelm- ingly been e-glass supported FR-4 resin laminates. This is due to the excellent dimensional stability and reasonably acceptable thermal performance (based on glass transition temperature and de- composition temperature). IMPACT Washington, D.C. 2016: Industry Leaders Advocate for a Pro-Manufacturing Policy Agenda IPC places a high priority on educating govern- ment officials about key policy issues of impor- tance to the electronics industry. That's why top executives from leading electronics companies gathered in Washington, D.C. recently for "IM- PACT Washington, D.C. 2016." NASA Investigates 3D Printing for Building Densely Populated Electronic Assemblies As detector assemblies get smaller and denser— packed with electronic components that all must be electrically connected to sense and read out signals—it's becoming increasingly more challeng- ing to design and manufacture these all-important instrument devices. Dragon Finalizing Departure Preps The SpaceX Dragon is being packed with critical science today and tomorrow before its release and splashdown on Wednesday. The crew is also re- viewing Dragon departure procedures and train- ing for its release from the grip of the Canadarm2 robotic arm. Beyond FR-4: High Performance Materials for Advanced Designs, Part 2 In Part 1, we covered basic FR-4 and variants that have been used in the commercial and military market for the past few decades, but in this col- umn we will delve into the newer materials that target a specific application and/or market seg- ment. Industry Weighs in on Green Aviation Tech Aviation's future is bright…green. That was the environmentally promising message delivered during the Green Aviation Technical Interchange Meeting (TIM), held recently at NASA Langley Re- search Center in Hampton, Va. NASA, Virginia Tech Test Management Platform for Unmanned Aircraft Traffic Efforts to protect air travelers are becoming es- sential as business leaders ramp up efforts to use unmanned aircraft for agriculture, real estate, in- spections, and commercial purposes, officials from the Virginia Tech Mid-Atlantic Aviation Partnership said. Raytheon to Start Production of First Multi-spectral Targeting System The U.S. Air Force awarded Raytheon Company a $90 million first-lot production contract for the next-generation Multi-Spectral Targeting System. The AN/DAS-4, the latest variant of the MTS fam- ily of sensors, incorporates greater fire control and Target Location Accuracy technology for precise coordinates. NASA Space Launch System's First Flight to Send Small Sci-Tech Satellites into Space The first flight of NASA's new rocket, the Space Launch System (SLS), will carry 13 CubeSats to test innovative ideas along with an un-crewed Ori- on spacecraft in 2018. Station Readies for BEAM Expansion The Expedition 47 crew is getting a new module recently attached to the Tranquility module ready for expansion later this week. The International Space Station residents are also running experi- ments today exploring a wide variety of phenom- ena and checking station gear. MilAero007 Highlights
