failure analysis services that we have been providing to the circuit board and EMS world for years. We are taking our increased knowledge and applying what we have learned to other sectors and industries, going well beyond PCBAs and electronics. Our key cus- tomer is an engineer with a problem requiring an immediate solution. Our goal is to provide that solution or at least a direction to pursue.” Boguski adds that Datest is now


an active member of ASNT, the Amer- ican Society for Non-Destructive Test- ing, and is able to draw on technical resources from that relationship as well. Datest is the West Coast demon- stration site for SPEA systems and has plans to install a SPEA 4080 fly-


ing probe test system this fall. An ISO 9001- and AS9100-certi-


fied company, Datest provides ad- vanced test engineering and inspec- tion services to the electronics con- tract manufacturing and OEM com- munities, and many other industries. The company, with over 30 years of expertise, offers in-circuit testing (ICT), flying probe testing, X-ray in- spection, boundary scan/JTAG test- ing, functional testing, failure analy- sis, and other related services. Dat- est is a member of IPC, SMTA, IEEE and ASNT. Contact: Datest, 47819 Westing-

Bringing Memristors to the Masses


Ann Arbor, MI — A new way of ar- ranging advanced computer compo- nents called “memristors” on a chip could enable them to be used for gen- eral computing, which could cut en- ergy consumption by a factor of 100. This would improve performance in low power environments such as smartphones or make for more effi- cient supercomputers. “Historically, the semiconductor


industry has improved performance by making devices faster. But al- though the processors and memories are very fast, they can’t be efficient because they have to wait for data to come in and out,” says Wei Lu, Uni- versity of Michigan professor of elec- trical and computer engineering and cofounder of memristor startup Crossbar, Inc. A portmanteau of memory and


resistor, memristors can be pro- grammed to have different resistance


Only Sonobond delivers these ultrasonic welding advantages…


• Exclusive tin-coated wire splicing, as well as welding aluminum, copper, nickel alloys, precious metals and dissimilar metals.


• One-pulse wire splicing up to 100mm2 and tinned .


wire to 60mm2


• Spot welds and wire-to-terminal welds also delivered in a single hit. Welding by time, energy, or distance.


• Durable Taper Lock tips that last up to 100,000 welds.


• Fast, easy tooling changes with no re-calibration required.

states —meaning they store informa- tion as resistance levels. These cir- cuit elements enable memory and processing in the same device, cut- ting out the data transfer bottleneck experienced by conventional comput- ers in which the memory is separate from the processor. However, unlike ordinary bits,


which are 1 or 0, memristors can have resistances that are on a contin- uum. Some applications, such as computing that mimics the brain (neuromorphic), take advantage of the analog nature of memristors. But for ordinary computing, trying to dif- ferentiate among small variations in the current passing through a mem- ristor device is not precise enough for numerical calculations. Lu and his colleagues got


around this problem by digitizing the current outputs — defining current ranges as specific bit values (i.e., 0 or 1). The team was also able to map large mathematical problems into smaller blocks within the array, im- Continued on page 8
