Mobile computing Because the development of similar Internet of Things (M2M) applications has driven the demand for mobile solutions, mobile computing has become mainstream. In the past few years, although the consumer-grade handheld device market has grown dramatically, they have not been able to replace rugged handheld devices because they cannot meet the requirements for ruggedness. Rugged handheld device The rugged handheld device is designed to remain intact in daily use in harsh environments, including drops, water immersion, high vibration and extreme temperatures, and destructive factors such as EMI and RFI. Typically, rugged handheld devices have an IP67 (protection rating) rating and meet the MIL-STD (US military standard) drop test standards. Commercial-grade handheld device manufacturers have tried to use secondary market accessories to make their devices sturdy, but the effect is very limited, thus proving that "similar to ruggedness" is completely different from "designed ruggedness." Robust design means that all aspects of the device must take into account rugged specifications, from component selection to sealing and protection of vulnerable areas. In Other words, rugged equipment is rugged both inside and outside. Rugged handheld devices are expensive, usually they cost twice as much as commercial handheld devices, but the ruggedized version saves costs during their lifetime because they experience less downtime and are more reliable in daily use , And the service life is longer. Obviously the cost of downtime exceeds the impact on direct users – they also disappoint customers. Not surprisingly, a recent study by VDC Research (2011) showed that from the perspective of total cost of ownership (TCO), ruggedized equipment is not that expensive during a five-year period. Expect The market for rugged handheld devices is expected to continue to grow rapidly in the coming years, as evidenced by the following trends: Smart staff. Institutions give staff more freedom and responsibility-through "smart network" support, the number of applications for each mobile device must be increased; the functions and processing capabilities of existing devices need to be improved. In addition, the “always on†connection of field staff requires a relatively inexpensive and extremely reliable embedded wireless solution. Sustainability. The trend to reduce carbon dioxide emissions, reduce fuel costs and reduce paperwork requires rugged mobile communication systems to support these attempts. At the same time, rugged handheld devices are converging; it used to be a separate barcode scanner, RFID reader and camera, and now it is clear that it needs to be integrated into one device without making it too complicated. remote diagnosis. Such as home treatment of healthcare, development of remote health services for patients and the elderly will affect this market. Improved support for voice command applications adds a new dimension of healthcare, and the rugged system also supports rapid expansion in education and preventive healthcare. Rugged parts As mentioned earlier, rugged equipment is rugged both inside and outside. For component suppliers like interconnection manufacturer FCI, this means closely following the requirements of "durability", from the component level, to meet the IP and MIL-STD standards. The established interconnect manufacturer understands the functions of the product, such as double beam contact, long sliding distance, flat female connector and high retention, which can bring the specific product advantages required for rugged equipment. This is why standard consumer-grade connectors do not work in a rugged environment: they do not support these special needs. Sometimes commercial-grade connectors can be upgraded to meet the needs of durability, which makes the industry's standard input / output or memory card connectors most meaningful. For example, FCI changed the standard SD card connector in the consumer market (using an SD card to program / store information for the device) to withstand high vibration, higher ambient temperature, and more than 10,000 cycles of mating capabilities. Not surprisingly, this connector is very successful in rugged handheld devices. However, the real challenge for interconnect manufacturers is to use new designs that must meet new requirements (such as miniaturization) without compromising ruggedness standards. This is where real experience and design experts come into play. For example, last year, several rugged handheld device manufacturers asked FCI to miniaturize the successfully developed and durable 1.00 mm pitch Conan mezzanine connector and reduce it to 0.50 mm pitch while maintaining the same performance. It turns out that this is a real challenge facing the project, but in the end FCI designed a revolutionary new connector, called MezzoStak ™ 0.5 mm mezzanine connector, built on a high temperature, high pressure, fault-tolerant non-polar interface, in Rugged and portable electronic products are used under extreme conditions recognized by customers.
