LED based lighting is now a very hot topic (believe me, in electronic thermal management circles that used to be funny, the first few times). Control of packaged IC junction temperatures will always have a bearing on reliability but for LEDs thermal also effects functional performance in terms of brightness and colour. The hotter they get, the dimmer they appear. A particular … [Read more...]
Self-Healing Electronics Could Work Longer, Reduce Waste
A team of University of Illinois engineers has developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink. Led by aerospace engineering professor Scott White and materials science and engineering professor Nancy Sottos, the researchers published their results in the journal Advanced Materials. As electronic … [Read more...]
IBM Retiree Wins Award from Engineers Society
Robert E. Simons was named the 2011 winner of the Allan D. Kraus Thermal Management Medal given recently by the committee that manages the annual award for the American Society of Mechanical Engineers. Simons is a retired IBM senior technical staff member who has had a 45-year career in the management of heat in electronics and holds more than 130 patents. He joined IBM in 1966 … [Read more...]
New Capacitors with Low Insertion Height
TDK-EPC has developed a wide range of EPCOS MKP and MKT film capacitors with low insertion heights. The new capacitors with a lead spacing of 37.5 mm feature insertion heights of only 15 or 19 mm. These components are designed for rated voltages of between 63 and 2000 V DC or 250 to 400 V AC. Their capacitance ranges from 0.1 to 82 µF. Depending on type and technology (MKT or … [Read more...]
Precision High Voltage Modules
Spellman High Voltage Electronics Corporation’s new V6 high precision, cost-effective high voltage modules on a common platform include either AC or DC input, with analog or digital interface (RS232) capabilities. The V6 Series offers output voltages ranging from 500V to 30kV, and incorporates the high precision features of Spellman’s 600 Series (replacing the 602C, 603C, 605C … [Read more...]
