AUGUST 2019 I DESIGN007 MAGAZINE 65 small- and mid-sized electronics manufactur- ers, understanding that enterprises relying on high-volume, commoditized boards for mass production are a different animal. For these larger enterprises, there are opportunities to renegotiate overseas supplier contracts or even influence where their suppliers buy raw mate- rials. Smaller organizations needing a lower vol- ume of PCBs face greater relative risk to the bottom line. The added cost and uncertainty associated with international trade can help make domestic manufacturing more appeal- ing. We understand that even PCBs made in the U.S. will likely have raw materials from China but producing boards here does not present risk like a move to Vietnam or China. Moving PCBs to be made in America offers multiple advantages. You can eliminate the risk associated with uneven quality, delays common with transatlantic shipping, and risks to your intellectual property. We also encour- age our customers to look for hidden costs of offshoring and seriously consider its less quan- tifiable pain points, like the impact on inven- tory management and burden on the domestic operation. The longer tariffs remain in place, the more likely cost-benefit analysis tips in favor of U.S.- produced PCBs. Uncertain trade policy causes us to closely examine our hidden assumptions about offshoring paradigms. You might find that a domestic manufacturer that specializes in low-volume, high-mix manufacturing pro- vides a viable alternative to increasingly costly and risky Chinese production.

The rover's 7-foot-long (2.1-meter- long) arm handily maneuvers 88 pounds' (40 kilograms') worth of sensor-laden turret as it moves from a deployed to a stowed configuration. On Mars, the arm and turret will work together, allowing the rover to work as a human geologist would: by reaching out to interesting geologic features, abrading, analyzing and even collecting them for further study via Mars 2020's Sample Caching System, which will collect samples of Mar- tian rock and soil. "Standing there, watching the arm and turret go through their motions, you can't help but marvel that the rover will be in space in less than a year from now and performing these exact movements on Mars in less than two," said Dave Levine, integration engineer for Mars 2020. Mars 2020 will launch in July 2020. It will land at Jezero Crater on Feb. 18, 2021. (Source: NASA) NASA's Mars 2020 Rover Does Biceps Curls
