In spite of the incredible advances in semiconductor integration levels, there are still numerous components that are not integrated. Passives are right at the top of that list. High value capacitors, low value resistors, and all sizes of inductors are very difficult to obtain in integrated circuit technology. This challenges manufacturers of these components to differentiate their products by meeting or exceeding the performance requirements of increasingly challenging application requirements. For example, in portable devices the size must shrink but the values cannot. In addition, the packaging for passive components must be compatible with the assembly technology used for the end product. In more and more instances, this dictates surface mount technology (SMT). Other requirements for passives are similar to those for all electronic circuitry, such as meeting regionally legislated requirements such as lead-free material per Directive 2002/95/EC for Reduction of Hazardous Substances (RoHS). Coping with these requirements for inductors, resistors, and capacitors imposes greater cost challenges than other components.
This section includes some products that work intimately with semiconductors and ICs to simplify the ways that users can handle more difficult or delicate components. These ICs also improve the thermal conductivity to boost power-handling capability of power semiconductors and ICs. The capacitors, inductors, and resistors support trends of smaller size, higher power, and SMT assembly, many products targeting all three trends simultaneously.
This Gadget Freak Review looks at a keyless Bluetooth padlock that works with your smartphone, along with a system that tracks your sleep behavior and wakes you at the perfect time in your sleep cycle to avoid morning grogginess.
Siemens released Intosite, a cloud-based, location-aware SaaS app that lets users navigate a virtual production facility in much of the same fashion as traversing through Google Earth. Users can access PLM, IT, and other pertinent information for specific points on a factory floor or at an outdoor location.
Since 1987, teams of engineers around the world have built solar cars to participate in a road race around Australia called the World Solar Challenge, being tested on the race time, kilometers traveled, practicality, and energy used by the vehicles they invent.
