Reliability drive for vehicle connectors
Rugged connectors are meeting the rapidly changing requirements of the modern motor vehicle platform. Today’s vehicles are heading into new territory, due to smart and adaptable interconnect products.
[ + ]European PV market faces sharp decline
Rapidly falling prices in the first half of this year have been unable to stimulate the faltering European photovoltaic market, according to the latest Solarbuzz European PV Markets report.
[ + ]Quantum dots throw more light on LEDs
By nestling quantum dots in an insulating egg-crate structure, researchers at the Harvard School of Engineering and Applied Sciences have demonstrated a new architecture for quantum-dot light-emitting devices (QD-LEDs).
[ + ]Polymer may give better lithium batteries
Lithium-ion batteries are everywhere, in smart phones, laptops, an array of other consumer electronics and the newest electric cars. Good as they are, they could be much better, especially when it comes to lowering the cost and extending the range of electric cars. To do that, batteries need to store a lot more energy.
[ + ]S-parameters are a sine of the future
If you work with high-speed serial links such as PCIe, USB, SATA, Infiniband or gigabit ethernet, you have encountered S-parameters. This method of describing the electrical properties of interconnects, standard in the microwave world for more than 60 years, is becoming the de facto standard in the high-speed digital world as well.
[ + ]Making PCBs EMC compliant
PCB board design is often governed by established cost aspects. If a designer comes up with an EMC-proof design (in theory difficult, if not impossible to achieve without actually testing it as a product), they are likely to hear that it’s going to be expensive to lay it out according to their wishes.
[ + ]Module without bond wires, solder and thermal paste
Power module packaging is driven by the ever-increasing demand for higher power densities, reliability improvements and further cost reductions.
[ + ]Solar cells reach new efficiency level
The Belgian research centre imec, together with Plextronics and Solvay, has produced an organic polymer-based single junction solar cell with 6.9% performance in an inverted device stack.
[ + ]Choke filtering, EMI and ethernet
Common mode chokes filter common mode EMI currents without causing signal degradation and without derating under high currents. These components are applied to pairs of conductors - supply and return.
[ + ]Staying on top of the eprocurement curve
Electronics, to make businesses more efficient through organising sales and record keeping and to reduce the quality of paper used, has been the holy grail of organisations since computers were welcomed into the fold as a business tool. In this article, the author looks at some of the achievements, challenges and pitfalls that a dedicated eprocurement system can bring.
[ + ]Impact of materials on microwave cable performance Part 2
The environments in which microwave cable assemblies are being used today are becoming more challenging with exposure to such conditions as extreme temperatures, chemicals, abrasion and flexing. Additional challenges include the need for smaller, lighter packaging for cable systems that last longer and cost less.
[ + ]Features that affect power performance
System power engineers have many choices in today’s power connector market and the list of options is growing as the industry diversifies to offer more specialised products. Here are some commonly asked questions:

[ + ]Throwing some light on power quality
According to Australian leading electronics solutions provider Benbro Electronics, electronic designers need to consider a number of factors to achieve power quality when designing a lighting system. This is more so with the advent of LEDS, compact fluorescent lighting (CFL), high intensity discharge (HID) lighting and other new technologies in lighting.
