What is 3D-MID? Molded parts with integrated electronics from HARTING

3D-MID (three-dimensional mechatronic integrated devices) technology combines electronic and mechanical functionalities into a single, 3D component. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.

Top 5 reasons for solder joint failure

Solder joint reliability is often a pain point in the design of an electronic system. According to Tyler Ferris at ANSYS, a wide variety of factors affect joint reliability, and any one of them can drastically reduce joint lifetime. Properly identifying and mitigating potential causes during the design and manufacturing process can prevent costly and difficult-to-solve problems later in a product lifecycle.

Bosch's gasoline system technology featured on nine of Ward's 10 Best Engines for 2012

With automakers squarely focused on meeting the 2025 CAFE regulations and consumers wanting more miles per gallon and lower emissions, Ward's 10 Best Engines of 2012 indicate the direction in which the automotive industry is headed: smaller, turbocharged engines with direct injection.

Bosch technology is featured on nine of the 10 Best Engines of 2012, and its direct-injection technology appears on five of the winning engines. The main elements of the Bosch direct-injection system include the engine control unit, high-pressure pump, and high-pressure fuel injector.

"Providing advanced technologies, such as direct injection and turbocharging, are essential in helping automakers meet the demand to bring the most fuel-efficient vehicles to market," says Sujit Jain, regional president, Gasoline Systems North America, Robert Bosch LLC.

By 2016, the number of highly efficient four-cylinder engines will increase by 20% to more than 20 million units globally, according to Bosch Mahle Turbo Systems, a joint venture between Bosch and MAHLE that produces turbochargers for passenger cars and commercial vehicles. "Based on this trend data," Jain says, "the forecast is clear: In the near future, every automaker will offer turbocharged gasoline engines."

In addition to direct-injection systems and components, Bosch technologies (including port fuel injectors, throttle body, oxygen sensor, mass air flow sensor, and other key sensors) are featured in nine of the winning engines:

• 5.0-liter DOHC V-8 (Ford Mustang Boss 302)
• 2.0-liter EcoBoost DOHC I-4 (Ford Edge)
• 2.0-liter TwinPower Turbo DOHC I-4 (BMW Z4/328i/528i)
• 3.0-liter TwinPower Turbo DOHC I-6 (BMW 135i, 335i, 535i, X3)
• 3.6-liter Pentastar DOHC V-6 (Chrysler 300S/Jeep Wrangler)
• 2.0-liter Skyactiv-G DOHC I-4 (Mazda3)
• 3.0-liter TFSI Supercharged DOHC V-6 (Audi A6)
• 2.0-liter Ecotec Turbocharged DOHC I-4 (Buick Regal GS)
• 1.6-liter Gamma DOHC I-4 (Kia Soul, Rio/Hyundai Veloster)

*Note: The only engine that does not use Bosch technology in the 2012 Ward lineup is the 3.5L DOHC V-6 HEV (Infiniti M35h).

As automakers strive to reach new CAFE standards of 54.5 mpg by 2025, Bosch's high-precision injection technology allows vehicles to consume less fuel and produce fewer emissions without sacrificing torque performance. This technology, coupled with turbocharging and variable valve timing, can lead to as much as an 18% percent reduction in fuel consumption and emissions.

In combination with additional technology packages and extreme downsizing, Bosch aims to achieve a 30% fuel-efficiency improvement for the gasoline engine. Bosch anticipates that in 2020, U.S. sales will reach 16.3 million vehicles, with 39% featuring gasoline direct injection.

"This lineup of engines honored by Ward's goes a long way toward changing customer perception about the relationship between engine size, fuel economy and power," Jain says. "These smaller engines are, in fact, powerful as well as fuel-efficient."

Selected by the editors of Penton Media Inc.'s Ward's Automotive Group, the 2012 list marks the 18th year for the Ward's 10 Best Engines program, the only awards in the North American auto industry that honor powertrain excellence. The awards were presented in Detroit on Jan. 11 during the North American International Auto Show.
