July 2016 • SMT Magazine 61 The TMSA technology described above is integrated into Goepel's 3D∙EyeZ measuring module, which is available in the stand-alone BasicLine AOI system and the new VarioLine system. The adjustable lateral resolution makes it possible to project a sufficient number of measuring points onto pins or into holes, and to record measurement values. Summary Swash circumference testing and embed- ment depth measurements of connectors or in- dividual pins place high demands on the mea- surement technology used. The sole use of or- thogonal or angled view inspection is not suit- able for this three-dimensional measuring task. Fringe projection based on triangulation also reaches its limits in this context, as shad- ing occurs on the one hand, and the detection of the pin tips can no longer be ensured on the other hand. It is also completely impossible to carry out depth measurements in holes using this method. The TMSA technology can eliminate the disadvantages described above. Integrated with the 3D∙EyeZ measuring module, the system is available inline or for stand-alone AOI systems. SMT Jens Kokott is product manager, AOI, at GOEPEL Electronic GmbH.

PERFECT PLACEMENT OF CONNECTORS AND PINS A microchip con- taining 1,000 indepen- dent programmable processors has been designed by a team at the University of Cali - fornia, Davis, Depart- ment of Electrical and Computer Engineer- ing. The energy-effi- cient "KiloCore" chip has a maximum com- putation rate of 1.78 trillion instructions per second and contains 621 million transistors. KiloCore is said to be the world's first 1,000-processor chip and is the highest clock-rate processor ever designed in a university, according to Bevan Baas, professor of electrical and computer engineering, who led the team that designed the chip architecture. While other multiple-processor chips have been created, none exceed about 300 processors, according to an analysis by Baas' team. Most were cre - ated for research pur- poses and few are sold commer cially. The KiloCore chip was fabricated by IBM using their 32 nm CMOS technology. The chip is the most energy-efficient "many-core" proces- sor ever reported, Baas said. For exam- ple, the 1,000 proces- sors can execute 115 billion instructions per second while dissipating only 0.7W. Applications already developed for the chip in- clude wireless coding/decoding, video processing, encryption, and others involving large amounts of parallel data such as scientific data applications and datacenter record processing.
