The problem of putting lead-free components into wireless devices may be at least partly solved. Previously, lead-free packaging had been prone to drop test failure. Phoenix-based FlipChip International says it has demonstrated significantly enhanced reliability in its drop test specification for its Wafer-Level Chip Scale Packaging (WLCSP) while using Enhanced Lead-Free (ELF) technology. The company notes the drop test robustness is a critical reliability requirement for WLCSP applications targeting advanced wireless handheld product applications where the device is at risk during the normal lifetime due to mechanical shock and vibration. FlipChip notes its ELF technology combines advanced lead-free metallurgy and polymer technologies to achieve these reliability improvements. The company says the ELF technology can be extended across all of FlipChip’s WLCSP products.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
