Sonic welding is now being used to crimp wires, cables, flex circuits, and other products where gas-tight and moisture-resistant connections are needed. The Sonicrimp technique, developed by Methode Development Co. (www.methode.com/mdc/), is said to be the first that works with these products, using a combination of high pressure and sonic energy to complete the electrical connection. Problems—including solder bridging and silver migration—are eliminated with the Sonicrimp technique, which can even be used on flat flex cables often used in automotive applications.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
