Surface Mount Printed Circuit Jumpers

MAY 23, 2014 – Keystone Electronics Corp. announces a new series of SMT PC Board Jumpers designed to link Circuit Board traces/tracks.

These space-saving SMT jumpers are quick and easy to set up and are uniquely suited as alternative options where thru-hole jumper use is not feasible.  As such, the new connectors are designed to provide ideal low profile circuit linkage and minimal footprint for high-density, high current PCB packages on power and aluminum backplanes.  All PCB soldering applications, including reflow, may be utilized.

Manufactured from Copper with silver plating, three different SMT Jumper styles are offered to meet individual preferences including:  Compact style, Cat. #5100 (bulk) or Cat. #5100TR (tape and reel); Micro-Miniature style, Cat. #5102 (bulk) or Cat. #5102TR (tape and reel); and Miniature Style, Cat. #5104 (bulk) or Cat. #5104TR (tape and reel).  All tape and reel parts are packaged per ANSI/EIA-481 standard for compatibility with most vacuum and mechanical pick and place assembly systems.

A Molecular Ballet Under The X-Ray Laser

Researchers capture snapshots of free molecules by the light of the free electron laser
Hamburg, 28 February 2014. An international team of researchers has used the world’s most powerful X-ray laser to take snapshots of free molecules. The research team headed by Prof. Jochen Küpper of the Hamburg Center for Free-Electron Laser Science (CFEL) choreographed a kind of molecular ballet in the X-ray beam. With this work, the researchers have cleared important hurdles on the way to X-ray images of individual molecules, as they explain in the scientific journal Physical Review Letters. CFEL is a cooperation of DESY, the University of Hamburg, and the Max Planck Society.

New Materials Could Increase Semiconductor Manufacturing in the U.S.

New materials are beginning to reinvent power and efficiency in cars, computers and consumer electronics

Changes may be coming that could expand the possibilities of semiconductor manufacturing in the United States, thanks to the discovery of materials that are readily available in the States. Several materials such the compound silicon carbide, a chemical compound of silicon and carbon will be tested for use in semiconductor manufacturing. The compound has been used as a ceramic, an abrasive and even as a component in bulletproof vests

Semiconductors are materials that conduct electricity better than insulators like glass, but worse than conductors like copper. While there are materials that exist with a higher “bandgap” than silicon– meaning they can operate more efficiently at higher voltages, frequencies and heats– they carry a hefty price tag.

“Currently they are expensive,” said Lucy Shi, a Ph.D. and assistant professor of engineering at the University of Illinois at Chicago. “They have a very bright future, but because silicon’s cost is so low it’s not going to be a one-day thing. There has to be major breakthroughs.”

Left Brain vs Right Brain From A Scientific Perspective


Ultrasound recording has shown that by the tenth week of gestation, the majority of fetuses move the right arm more than the left, and from the 15th week most suck the right thumb rather than the left —a strong indicator of later handedness.

Handedness and brain asymmetry are widely regarded as unique to humans, and associated with complementary functions such as a left-brain specialization for language and logic and a right-brain specialization for creativity and intuition. In fact, asymmetries are widespread among animals, and support the gradual evolution of asymmetrical functions such as language and tool use. Handedness and brain asymmetry are inborn and under partial genetic control, although the gene or genes responsible are not well established. Cognitive and emotional difficulties are sometimes associated with departures from the “norm” of right-handedness and left-brain language dominance, more often with the absence of these asymmetries than their reversal.

Google Contact Lens to Explore Tear Glucose Testing for Diabetics

The photo depicts the contact lens Google is testing to explore tear glucose. After years of scalding soldering hair-thin wires to miniaturize electronics, Brian Otis, Google X project lead, has burned his fingertips so often that he can no longer feel the tiny chips he made from scratch in Google’s Silicon Valley headquarters.

Brian Otis gingerly holds what looks like a typical contact lens on his index finger. Look closer. Sandwiched in this lens are two twinkling glitter-specks loaded with tens of thousands of miniaturized transistors. It’s ringed with a hair-thin antenna. Together these remarkable miniature electronics can monitor glucose levels in tears of diabetics and then wirelessly transmit them to a handheld device.

“It doesn’t look like much, but it was a crazy amount of work to get everything so very small,” he said before the project was unveiled.

During years of soldering hair-thin wires to miniaturize electronics, Otis burned his fingertips so often that he can no longer feel the tiny chips he made from scratch in Google’s Silicon Valley headquarters, a small price to pay for what he says is the smallest wireless glucose sensor ever made.

The results of this study have implications for helping both type 1 and type 2 diabetic patients

Source: University of Pennsylvania School of Medicine — Klaus Kaestner PhD, professor of Genetics and postdoctoral Dana Avrahami, PhD, from the Perelman School of Medicine, University of Pennsylvania, published a study this week in the Journal of Clinical Investigation, In which they were able to replicate human pancreatic beta cells – the cells in our body that produce the critical hormone insulin. The newly replicated cells retained features of mature beta cells and showed a physiological response to glucose. Continue reading
